Stainless steel gearboxes are widely used in industrial transmission fields due to their high strength and corrosion resistance. However, in actual use, stainless steel gearboxes may still malfunction due to improper design, installation, lubrication or maintenance....
GEG C Heavy-Duty Spherical Plain Bearing – Maintenance-Free PTFE
GEG C Heavy-Duty Spherical Plain Bearing is a documented maintenance-free series for industrial linkage or pivot applications. Heavy-envelope maintenance-free bearing; ptfe composite sliding surface. Use the main image for identification and the full product description for model-by-model dimensions and load data.
MOQ: 50 pcs. Minimum order value USD 1,500; mixed orders and trial quantities welcome.
GEG C keeps the maintenance-free PTFE sliding system but uses the heavier GEG envelope. The available bore range in the supplied catalogue is 6–30 mm. It is a useful option when the design needs more bearing section around a small shaft yet still wants to avoid routine lubrication.

Typical Applications
Selection Guide
Compare the full outside diameter and width with the housing before choosing GEG C over GE C. The larger envelope changes shoulder and snap-ring space as well as press tooling.
Installation & Maintenance
The PTFE system is intended for maintenance-free operation. Avoid contaminating it with assembly paste or shop debris.
Related Bearings
GE C offers the standard maintenance-free envelope; GEG E / GEG ES 2RS is the serviceable heavy family; PB uses a bronze-lined maintenance-required construction.
