UCT 208 bearing dimensions & suffix variants
Look up recorded dimensions for designations beginning with UCT 208. The table retains complete manufacturer designations so special suffixes and different dimensional variants remain visible.

Find by measured dimensions
Enter bore d, outside diameter D and width B. Use decimals or inch fractions such as 1/2 or 1 1/4.
UCT 208 dimensions and recorded technical data
Use the named dimensions for each complete record below. A generic d×D×B answer is not asserted where the base record is missing, dimension symbols are unverified, or the product uses a different geometry such as a housing or thrust assembly. Suffix records are not substituted for a missing base specification.
The numeric series boundary is preserved: a longer number is not included merely because its first digits match. 5 recorded variants are listed. A dash means the value is missing, not zero.
Read the original dimensions for UCT 208
Boundary size alone does not describe every ring, shoulder or assembled unit. These tables retain the recorded manufacturer labels, symbols, units and limits for each complete marking. Expand a record to check its detailed measurements.
Important: an approximate value, a minimum or a maximum keeps that qualifier. These reference extracts are not CAD drawings, fit recommendations or replacement approvals.
FAG UCT208 — 20 dimension fields
Take-up housing unit. Source: Schaeffler medias — FAG; recorded snapshot 2026-09-02.
This record can describe a housed unit rather than a loose bearing. Housing length, bolt spacing and centre height must be checked separately from shaft bore; do not interpret them as bearing outside diameter.
Minimum and maximum mounting dimensions are limits, not nominal bearing dimensions. Check shaft/housing shoulders and fillets against the current drawing before designing a seat.

Catalogue parameters for UCT 208
Choose the complete brand and marking before reading a value. These source-labelled records add dimensions, construction and engineering properties where they were recorded; a shared model number does not establish interchangeability.
Units, ranges and minimum/maximum qualifiers are retained. The data is a dated catalogue reference, not a certified drawing, a complete current specification or an operating approval.
KOYO UCT208 — 21 recorded parameters
Ball bearing unit
Reference: JTEKT / Koyo catalogue; source snapshot 2026-09-02.
This can be a unit or housing record. Bolt spacing, housing envelope, centre height and the insert identity need separate checks; do not interpret every outside dimension as bearing D.
Values shown are retained from the recorded source. Zero boundary dimensions and zero load ratings from incomplete legacy feeds are withheld rather than presented as usable specifications.

NTN UCT208 — 19 recorded parameters
Bearing units
Reference: NTN Europe public product catalogue; source snapshot 2026-10-02.
The original dimension names below control this record. Component, washer and assembly measurements must not be substituted for each other.
Recorded closure for UCT208: seal with slinger. Match the entire marking, including one-sided versus two-sided closure. A shared base number does not establish the same seal or shield across brands.
Use grease- and oil-qualified speed entries only for the named lubrication condition. Dynamic C and static C0 are catalogue ratings, not a universal safe load or installation approval; shoulder and fillet limits are separate from boundary size.

How to compare these values
- Use the displayed dimension names and original symbols. Housing length L, height H2 and flange width are not bearing outside diameter D. A catalogue width with an unverified symbol must not be assumed to be inner-ring width B or assembly width T. Open the product record for mounting dimensions and geometry.
- Inch values are calculated from the recorded millimetres using 25.4 mm per inch, rounded to six decimal places. They do not change a metric bearing into an inch-series bearing. Gram values are converted from the recorded mass in kilograms.
- C and C0 describe different rating conditions. They are not a single safe working-load limit and cannot replace an application load calculation.
- Reference and limiting speeds are separate catalogue values. The source grease/oil context is shown where recorded. Lubricant, seals, loads, fit, clearance and cooling affect the usable operating speed.
- A common base number does not prove equivalent seals, clearance, precision, material or interchangeability. Open the full designation for these fields.
Related prefix matches — other model numbers may appear
These discovery results can contain a longer number or a different component. They are not specifications for the requested exact model. Open the complete product to inspect its original geometry.
Check the drawing before substituting
Nominal dimensions are not shaft-fit tolerances. Different variants can add grooves, flanges, wider rings or assembly components. When the table has different dimensions, the complete designation—not the shared prefix—controls.
Reference basis & data limits
Manufacturer terminology is retained in the product records. Technical reference basis: JTEKT Basic Bearing Knowledge (boundary dimensions, tolerance classes and lubrication); NSK Bearing ABCs (lubrication, designations and clearance); NTN technical FAQs (closure codes and component interchange); SKF rolling-bearing selection and maintenance references.
Selection workflows and catalogue grouping are BearingScope editorial aids. Verify the current drawing and application requirements before using a candidate. Missing database information is not converted into an assumed match.
