Independent brand reference
Return to results ↑NSK bearings: identification, catalogue & comparison
NSK Ltd. is a bearing manufacturer established in 1916. Its industrial business includes bearings and precision machinery components; its automotive business also includes bearings. NSK on a ring is the brand identity, not a complete size or performance specification.
NSK bearing types & model examples
Start with the bearing's construction, not just its diameter or brand. These source-backed examples connect a bearing type to actual NSK designations and recorded dimensions. They are lookup starting points, not a recommendation for an unspecified machine or a complete current catalogue.
NSK Ball bearings3 model examples
Ball bearings are a group of constructions, not one interchangeable design. Deep-groove, angular-contact and self-aligning bearings serve different arrangements; the exact type remains part of the lookup.
Before selecting a model
- Identify whether the arrangement uses deep-groove, angular-contact or self-aligning construction.
- Check the full marking, dimensions, closure and internal clearance on the individual record.
- Use the row count and mounting arrangement from the exact model; do not infer them from the word ball.

Comparison boundary: The group name alone does not determine load direction, speed, accuracy or installation requirements. Preserve the full designation and suffix. Equal dimensions alone do not establish interchangeability; blank values remain unknown.

A versatile radial bearing family with some axial-load capability; single and double rows differ.
Before selecting a model
- Match envelope, load ratings, closure, clearance, cage, tolerance class and lubrication.

Comparison boundary: Open, shielded and sealed variants may share dimensions while closure, grease or clearance differs. Preserve the full designation and suffix. Equal dimensions alone do not establish interchangeability; blank values remain unknown.
Construction & selection guide →Dimensions retain their source labels: B is not automatically the same as assembly width T, ring width C or section height H. A component with no inner ring may specify Fw rather than a shaft bore d. These examples do not supply installation fits, approval for a machine, or a promised load/speed capability.
What to identify first
Separate the bearing's base designation from its closure, internal-clearance and grease information. Two NSK records with the same base number can have different closures and limiting speeds.
3,828 records currently loaded here. This is BearingScope's coverage, not the manufacturer's entire catalogue. A missing result means a data gap in this website, not that the manufacturer has never made the product.
Find the correct catalogue record
NSK's Rolling Bearings for Industrial Machinery catalogue separates dimensional tables, designations and engineering guidance. A product series page can show several variants. Match the complete designation, clearance and tolerance selection before reading a speed or load value. Registration-dependent CAD/PDF services are not reproduced here.
Use the designation field above for the full marking, or enter bore d, outside diameter D and width B in mm. Leave unknown fields blank. A size chart can find candidates; it cannot establish material, precision or assembly compatibility by itself.
Read the NSK designation in context
These are interpretation notes, not a universal suffix crosswalk. Preserve every unrecognised code for exact-model verification.
| Marking or field | Meaning and limits |
|---|---|
| ZZ / Z | For the documented single-row deep-groove system, ZZ means shields on both sides; Z means a shield on one side. |
| DDU / DU | DDU means rubber contact seals on both sides; DU means a rubber contact seal on one side in that system. |
| VV / V | VV means rubber non-contact seals on both sides; V means a non-contact seal on one side in that system. |
| Clearance and grease | Keep CN, C3, CM and grease information distinct. An electric-motor clearance designation is not a universal shaft tolerance or a grease specification. |
NSK suffix cross-reference boundaries
A label such as DDU explains a closure within its NSK family. It does not, on its own, prove that another brand's contact seal has the same grease, friction, speed rating or lip construction. Use a complete model comparison after decoding the marking.
Compare NSK with another brand
- Start with the complete designation and supplied component or assembly.
- Compare d×D×B in the same units; for separable bearings include the correct component and assembled dimensions.
- Check closure, clearance, cage, precision, material and lubrication. A blank field remains unknown.
- Compare load and speed figures on the same basis, then check the application's mounting and operating requirements.
Equal boundary dimensions identify a candidate, not an approved replacement. BearingScope does not rank whole brands or certify fitment.
NSK bearing lookup questions
Is this the official NSK catalogue or a shop?
No. BearingScope is an independent lookup and comparison reference. It does not sell bearings, quote prices, certify authenticity or claim to contain the manufacturer's complete current range.
Can I search by inside and outside diameter?
Yes, where corresponding product data is loaded. Enter known dimensions in mm in the search controls above. Add width and family to narrow the result. Measure the loose bearing's boundary dimensions, not a housing's mounting-bolt spacing. Keep uncertain readings separate from exact measurements.
Does a catalogue number prove that the bearing is genuine?
No. A plausible marking or a matching database record does not authenticate a physical item. Retain the full marking, packaging and lot identification for the manufacturer's verification process; neither a photograph nor a country name alone settles authenticity.
Where was my NSK bearing made?
The site does not have a verified factory/lot register. Brand identity and catalogue dimensions cannot establish an individual bearing's manufacturing origin. Check that item's traceability documentation; the missing origin is not filled from another model.
Can I download every NSK PDF or CAD drawing here?
No. Public lookup records and explanatory guides are not a complete document library. A drawing must match the exact model and revision and be permitted for redistribution. Where no such file is provided, the document request remains a data gap.
What if the full suffix gives no result?
Check the lettering, separators and component identity first. You may use the base number to discover related records, but do not remove the suffix from the part you ultimately compare. Record the missing full designation through the site's data-feedback page.
