Product Overview

CSA keeps the eccentric-collar concept of SA but uses a cylindrical outer diameter. That makes the housing-seat geometry the decisive difference when choosing between SA and CSA.

The published drawing and dimensional table follow the GBC insert-bearing catalogue for this CSA series. It is defined by eccentric locking collar, a cylindrical outside diameter (c-prefix catalogue convention), and the dimensional rows listed below. For broader bearing navigation, explore the Bearings range.

Dimensional Drawing

The drawing below is cropped directly from the supplied catalogue. Use its dimension letters with the table; do not scale the image to estimate dimensions.

Technical Parameters

Base metric rows and documented catalogue models are shown here. Inch-bore suffixes remain available where they appear in the catalogue; quote the complete suffix when an inch shaft is involved. Load ratings are catalogue values and should be checked together with duty, speed, lubrication and mounting conditions.

Selection and Housing Match

Match the full CSA code and confirm D, B and B1. If the old insert is marked SA rather than CSA, stop and verify the housing before ordering because the outside diameter form is different.

Installation Notes

Check the cylindrical seat for roundness and correct fit. Because this outer ring is not the spherical SA form, do not rely on housing self-alignment to compensate for a mislocated seat. Lock the eccentric collar only after the insert is correctly positioned.

The catalogue installation note for eccentric locking types is to rotate the eccentric collar in the direction of shaft rotation, then tighten the set screw on the collar. Keep the collar and shaft clean so the locking action is repeatable.

Catalogue Construction Notes

The catalogue describes insert bearings as single-row deep-groove ball bearings and shows dual-seal and triple-lip sealing arrangements within the product family. It also documents hardened inner-ring areas and an anti-rotation device used when a spherical insert is fitted with clearance in its housing. Confirm the exact suffix when a particular seal is required.

Typical Applications

This series is considered for cartridge-style arrangements, compact conveyors and machinery using a straight outer-ring seat. Application fit still depends on shaft size, housing geometry, contamination, relubrication needs and the real radial/axial load pattern. For food-processing equipment, specify any material, lubricant or washdown requirement explicitly rather than assuming the standard insert meets a hygienic specification.

Ordering Information

Model codes should be ordered exactly as documented. The catalogue uses -G for relubricatable versions in applicable SB/SA families, C-prefix notation for cylindrical outside-diameter variants, 2RS where the double-rubber-seal designation is part of the model, and +H for UK adapter-sleeve combinations. Not every suffix applies to every series.
