GE...ES Spherical Plain Bearings
Outer ring constructed from carbon chromium steel, fractured, hardened and phosphated, with sliding surface treated with MoS2. Inner ring made of carbon chromium steel, hardened and phosphated, with sliding surface treated with MoS. All bearings feature an annular groove and lubrication holes in each ring except those of the E design. Bearings of the 2RS design are equipped with seals at both sides.

Usage Questions & Answers
Where is the GE...ES bearing used?
These bearings handle high radial loads with oscillating motion, making them ideal for heavy machinery linkages, hydraulic cylinder joints, and pivot points in construction, agricultural, and material handling equipment.
How to choose the right type?
Match the bearing type to your operating environment:
- Standard Type: For maintainable, high-load applications
- 2RS Sealed Type: For dirty or wet conditions requiring contamination protection
- E Maintenance-Free Type: Where lubrication access is impossible or impractical
How to install it correctly?
Ensure proper fits: interference fit for housing, clearance fit for shaft. Press-fit only the required ring using correct tools—never strike sliding surfaces directly. Axially secure the bearing after installation to prevent movement.
How to lubricate?
Fully grease standard and 2RS types before use and relubricate periodically via lubrication nipple. Do not lubricate E-type bearings as they are maintenance-free.
Purchasing Guide
Heavy-Duty Oscillating Applications
(e.g., excavator linkages, crane pivots)
Recommend: Standard or 2RS type for high load and shock resistance
Harsh Environment & Low Maintenance
(e.g., agricultural gear, outdoor conveyors)
Recommend: 2RS or E type for seal protection against dirt and moisture
General Industrial Articulation
(e.g., valve actuators, machinery joints)
Recommend: Standard type for clean environments; 2RS if sealed protection is needed
Key Specifications to Confirm:
- Size (bore, OD, width)
- Correct suffix (2RS / E)
- Load rating vs. application needs
- Standard phosphating & MoS2 coating included
