GE C is a compact maintenance-free radial spherical plain bearing. The outer ring is pressed around the inner ring and carries a PTFE composite sliding layer, while the spherical surface of the inner ring is chromium plated. The catalogue covers 6–30 mm bores.

Typical Applications
Automation pivots
Compact linkages without grease access
Oscillating joints in clean machinery
Selection Guide
This family is attractive where a grease line would complicate a compact assembly. Select by d, D, B and C first, then check the catalogue load ratings and tilt angle.
Installation & Maintenance
Do not add a grease routine to a PTFE maintenance-free bearing unless a project-specific engineering instruction explicitly calls for it.
Related Bearings
GEG C provides a heavier maintenance-free envelope; GE E / GE ES 2RS is serviceable and available across a much broader bore range; GE ET 2RS uses PTFE fabric and double seals.
FAQ
Outer ring pressed around the inner ring — what changes selection?
The surrounding housing must still be stiff enough to support the outer ring; maintenance-free does not mean insensitive to poor fits or edge loading.
Chromium-plated inner spherical surface — what should installers watch?
Keep the contact area clean, press on the correct ring during installation, and inspect for growing play rather than waiting for a lubrication symptom that this design does not have.
Oscillating joints in clean machinery — suitable duty?
Oscillating joints in clean machinery is a screening application for the GE-C series; final size follows the model table and actual joint duty.
