CSXU050-2RS bearing dimensions & suffix variants
Look up recorded dimensions for designations beginning with CSXU050-2RS. 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.
CSXU050-2RS 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. 1 recorded variants are listed. A dash means the value is missing, not zero.
Catalogue parameters for CSXU050-2RS
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.
INA CSXU050-2RS — 20 recorded parameters
Four-point contact bearing
Reference: Schaeffler medias — INA; source snapshot 2026-10-03.
CSXU050-2RS is a thin-section four-point-contact bearing, with a 127×146.05×12.7 mm envelope. These numbers are bore, outside diameter and width, not inch values.
The source records contact seals, a brass-sheet cage and PL1 classes. PL1 is retained as the manufacturer classification; it is not converted into an ABEC grade.
The current source designation omits the HLE text in the old page address; HLE is recorded as a logistical code. The two d1/D1 pairs in the table have different labels, so shoulder and calibre dimensions must not be merged.
Manufacturer product identity and parameters checked on 2026-10-03. A catalogue reference is not a certified drawing or an application approval.

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.
