SA Eccentric Locking Insert Bearing
Compact Eccentric Collar Type. Catalogue-backed dimensions, exact series drawing and RFQ support from GBC.

Product Overview
SA brings eccentric-collar locking to the compact insert-bearing range. It is a good fit when the existing unit was designed for an SA insert and the buyer wants collar locking rather than two set screws in the inner ring.
The published drawing and dimensional table follow the GBC insert-bearing catalogue for this SA series. It is defined by eccentric locking collar; -g relubricatable version shown, a spherical od for sa, and the dimensional rows listed below. For broader bearing navigation, explore the Bearings range.

Dimensional Drawing

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
Read the complete old marking and check shaft bore, D, B and B1. For dirty or frequently washed environments, discuss the relubricatable -G option and seal requirement rather than selecting by model code alone.
Installation Notes
Rotate the eccentric collar in the running direction to seat it, then lock its screw. Check B and B1 because the collar increases the axial space needed on one side of the bearing.
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 compact conveyors, textile machines and agricultural equipment using eccentric-locking units. 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.
FAQ
How should I select the correct SA model?
Read the complete old marking and check shaft bore, D, B and B1. For dirty or frequently washed environments, discuss the relubricatable -G option and seal requirement rather than selecting by model code alone.
What should I check before installing a SA insert bearing?
Rotate the eccentric collar in the running direction to seat it, then lock its screw. Check B and B1 because the collar increases the axial space needed on one side of the bearing.
Can I select a replacement from shaft diameter alone?
No. Shaft diameter is the starting point, but D, B, C, the outer-ring form, locking method and any suffix must also match the existing housing or machine drawing.
What information helps GBC quote accurately?
Send the bearing marking, shaft diameter, required quantity, housing or machine reference, operating environment, and a drawing or clear photos when available. For inch-bore rows, keep the complete suffix.
Send the Bearing Marking and Drawing
For a faster check, include the full SA model, shaft diameter, quantity, housing reference, duty details and any available machine drawing. GBC can then compare the request with the catalogue row without guessing an undocumented specification.
