Thrust ball bearings
1,137 dimension rows · 1,008 model records · FAG, NSK, SKF
Thrust ball bearings carry axial loads; a separate radial bearing is usually required.
Query 1,530 source-labelled models in 1,659 bearing or specified-seat configurations. Filter the shaft bore, outside envelope and complete height together. A housing-washer opening, one washer’s thickness or a roller diameter is not the same measurement.
Keep the shaft-washer bore distinct from the housing-washer opening. These ball-thrust records need separate radial support.
Filters update immediately. Dimensions match the envelope shown in each row; optional seat configurations are labelled separately and are not new catalogue part numbers. Changing construction clears dimension fields. Changing units converts valid inputs; inch results are conversions rounded to six decimals, not an inch-series classification.
1,137 configurations match. Showing 1–24.

No verified configuration matches these conditions in this snapshot. Check units, construction and the full marking. A nearby size is not substituted; absence here does not prove that a part does not exist.
Source-property snapshot 2026-10-03. The chart is an independent nominal-dimension reference, not a full catalogue, stock list, toleranced drawing or replacement approval. Separate washers/cages, combined radial/axial units, precision angular-contact assemblies and plain thrust pads need their own geometry. Rows without unambiguous manufacturer dimensions remain outside this chart. Construction guidance: NSK Thrust Ball Bearings and Bearing ABCs; dimensions and optional configurations: the retained manufacturer properties.
A thrust ball bearing supports axial load along the shaft. It is not designed to carry radial load. A single-direction assembly supports axial force in one direction; a double-direction assembly provides support in both directions.
| Part or design | What it does | What to verify |
|---|---|---|
| Shaft washer | Locates on the shaft side of the assembly. | Identify it separately from the housing washer. |
| Housing washer | Supports the other side of the ball-and-cage assembly. | Check the seat and support geometry. |
| Ball-and-cage assembly | One assembly in single-direction designs; two in double-direction designs. | Do not compare washer width with the assembled axial height. |
On a small screen, scroll the table horizontally to read all three columns.
Flat-seat and aligning-seat arrangements differ. A double-direction design has an intermediate shaft washer and two ball-and-cage assemblies; it is not created simply by reversing one single-direction bearing.
Provide radial guidance through an appropriate separate support. The word “thrust” does not by itself specify the required minimum axial load or permissible speed.
Technical reference basis: NSK: Thrust Ball Bearings. Explanation and lookup workflow: BearingScope. Manufacturer-specific limits remain attached to the exact product record.
Thrust and axial load both mean force along the shaft. Identify whether the part is a ball thrust bearing, roller thrust assembly or a sliding thrust pad before comparing sizes or installation instructions.
Axial force acts parallel to the shaft axis; radial force acts across it. A thrust ball bearing transfers axial force between its shaft and housing washers through the balls. It does not provide radial support. Another appropriate support must carry the radial duty in the machine.
| Question | Answer | Selection implication |
|---|---|---|
| Axial or thrust? | Two terms for the same load direction | Do not create separate load cases merely because the names differ. |
| One direction or two? | Direction refers to axial force, not rotation | A shaft can reverse rotation without making a single-direction unit double-direction. |
| Both radial and axial load? | Use a suitable combined-load arrangement or separate supports | An ordinary thrust ball bearing alone is not a combined-load bearing. |

A shaft washer and a housing washer serve different interfaces even when they look similar. Their bores and seating requirements can differ. Keep raceway faces toward the balls and identify every washer from the assembly drawing.
| Construction | Main components | Axial support |
|---|---|---|
| Single direction | Shaft washer, ball-and-cage assembly, housing washer | One axial direction. |
| Double direction | Central shaft washer, two ball-and-cage assemblies and two housing washers | Both axial directions. |
| Aligning-seat version | The specified spherical/aligning seat components | Helps accommodate mounting error within its documented scope. |

An aligning seat is not permission to impose radial load. Do not use a plain hardware washer as an unverified substitute for a bearing raceway washer.
Record the shaft-washer bore d, housing-washer outside diameter D and complete assembled height T as named in the drawing. Measure the correct seated stack; one loose washer's thickness or a cage-only height is not the complete bearing height.
| NSK reference model | d — bore | D — outside | T — height | Axial dynamic / static rating |
|---|---|---|---|---|
| 51104 | 20 mm | 35 mm | 10 mm | 15.1 / 26.6 kN |
| 51105 | 25 mm | 42 mm | 11 mm | 19.7 / 37.0 kN |
| 51205 | 25 mm | 47 mm | 15 mm | 28.0 / 50.5 kN |
On a small screen, scroll the table horizontally.
These are manufacturer-specific NSK reference records reviewed for this page. Ratings are axial basic ratings, not permitted working loads. The 25 mm bore shared by 51105 and 51205 does not make their envelopes interchangeable. All listed dimensions are nominal.
JTEKT lists 51100, 51200, 51300 and 51400 series with flat seats, 53200/53300/53400 with spherical seats, and the corresponding U-listed forms with aligning seat washers. These are series examples from that reference, not complete part numbers or universal suffix rules.
| Search wording | Identify this first | Do not substitute |
|---|---|---|
| Thrust ball / axial ball | Ball-and-washer construction and direction count | A radial deep-groove bearing based only on bore. |
| Roller or needle thrust | Roller geometry, cage and race-washer scope | A thrust ball stack of similar outside diameter. |
| Journal and thrust | Radial journal support versus axial support; rolling or sliding construction | An engine thrust surface with an industrial ball thrust bearing. |
| Tilting pad / fluid film / magnetic thrust | A different support mechanism | The installation and rating rules on this ball-bearing page. |

This checklist does not supply a machine-specific fit, nut torque, preload or end-play setting. A car's 'thrust bearing' may mean an engine thrust surface, clutch release bearing or another component that needs a separate service procedure.
Selection requires the actual axial load, duty cycle, speed and lubricant. A basic dynamic or static rating is not a free-standing safe working load. Check the exact bearing's speed and minimum-load conditions together with the installation.
SKF's thrust-bearing reference relates required minimum load to bearing factors and speed. An unloaded or lightly loaded rotating bearing cannot be approved just because its main load rating is large. No numerical minimum is inferred here without the correct bearing factor and conditions.
Manufacturer application examples are starting points. They do not approve a thrust ball bearing for every bandsaw guide, washing machine kit, vehicle, turbocharger or propeller-shaft installation.
| Application context | Useful question | Still required |
|---|---|---|
| Screw support or positioning stage | Where does the axial reaction go, and must it reverse? | Exact bearing arrangement, precision and stiffness requirements. |
| Vertical shaft | Which support carries weight and which guides radially? | Loads, retention, speed and lubrication delivery. |
| Rotating platform or pivot | Is there radial load or an overturning moment as well as thrust? | Complete support geometry, not only the axial rating. |
| Printer, reel or small mechanism | Is the supplied unit a separable stack or retained assembly? | Dimensions, sealing and the device's actual part identity. |

Use the full marking before choosing a size. In the NSK E1103d (2025) catalogue, the three seat constructions below have separate designations and heights. A number with U includes the specified aligning seat washer; it is not the same envelope as the flat-seat bearing.
These are NSK catalogue series, not universal rules for every manufacturer. A family prefix identifies a construction, not a complete available model. Use the exact rows and linked model records below.
| Axial directions | Flat seat | Aligning seat | With aligning seat washer |

| Single | 511 | Not listed | Not listed |
| Single | 512 | 532 | 532…U |
| Single | 513 | 533 | 533…U |
| Single | 514 | 534 | 534…U |
| Double | 522 | 542 | 542…U |

Example: 51200, 53200 and 53200U share a source row, but their complete dimensions are 10×26×11 mm, 10×26×11.6 mm and 10×28×13 mm respectively. Equal load ratings in that row do not make them directly interchangeable.
For the single-direction flat series, 51100, 51101, 51102 and 51103 have 10, 12, 15 and 17 mm bores. Do not extend that shortcut to double-direction numbers: 52202 has a 10 mm central-washer bore d2, while the separate d dimension in its drawing is 15 mm.
X qualifies washer geometry in these tables: the shaft/central washer outside diameter is smaller than the housing washer diameter. X does not mean an ABEC accuracy grade. Keep it in the marking.

An aligning seat changes the housing interface. The U version includes the matching aligning seat washer, so use its total outside diameter and total height. The bearing alone and the seat-washer assembly must remain separate comparison candidates.
The corresponding ratings are read from a shared source row, but component geometry and mass are specific to each construction. A spherical seat does not provide radial capacity or an unlimited self-aligning capability.

The mounting drawing distinguishes shaft and housing abutments from the bearing boundary dimensions. A maximum fillet radius controls interference at a corner; it is not an instruction to grind the raceway or a tolerance for the housing bore.
The single-direction tables list da minimum, Da maximum and ra maximum. The double-direction tables instead list Da, ra and rb; a missing shaft abutment value must not be invented from the single-direction row.

These are catalogue geometry examples, not a housing manufacturing drawing or a complete device repair procedure. No retaining torque, fitted clearance, preload force or minimum-load value is established by this table.
A 10 mm NSK 51100 is a small metric thrust bearing, not an inch-series 1/4 in bore bearing. Likewise, these industrial tables do not identify a similarly numbered wheel hub, clutch release bearing, banded assembly or an OEM machine repair kit.
Precision angular-contact thrust bearings, needle/roller thrust bearings and plain thrust pads use different structures and rating rules. They need their own source records rather than a renamed row from this ball-thrust chart.
No. This construction requires a separate appropriate radial support or a different combined-load bearing arrangement.
Identify the shaft and housing washers from their marking and drawing; their bores and seats can differ. Do not choose by cosmetic appearance.
No. It means that axial load can be reacted in both directions along the shaft.
No. Roller, needle, sliding-pad, fluid-film and magnetic thrust supports are different mechanisms. Use the correct family and machine instructions.
