GE...LO Automatic Transmission Spherical Plain Bearing

self-lubricating steel-on-PTFE misalignment tolerant

The GE...LO series spherical plain bearings are specifically engineered for automatic transmission applications where oscillating motion, high loads, and limited maintenance access are critical factors. Featuring a steel-on-PTFE composite sliding surface, the bearing provides maintenance-free operation with excellent wear resistance and low friction coefficients. The spherical inner ring design compensates for angular misalignment between shaft and housing, reducing stress on surrounding transmission components. The bearing is pre-lubricated with a special grease that remains effective across a wide temperature range of -40°C to +150°C. The LO designation indicates the bearing is equipped with a lubrication groove and holes in the outer ring, allowing for relubrication if required. Common applications include shift selector pivots, linkage joints, and actuator mounting points in modern automatic transmissions.

Technical inquiries

What does the LO designation mean in GE...LO bearings?

LO indicates the bearing is equipped with a lubrication groove and lubrication holes in the outer ring. This allows for relubrication during service intervals if the application demands extended maintenance cycles or if the bearing is exposed to high contamination levels.

What is the typical service life of GE...LO bearings?

Under normal operating conditions with proper alignment and load, GE...LO bearings provide service life exceeding 500,000 oscillation cycles. The PTFE composite sliding surface provides excellent wear resistance and maintains low friction over the bearing's operational life.

Can GE...LO bearings operate without relubrication?

Yes, the PTFE composite sliding surface provides inherent lubrication, making the bearing maintenance-free for most applications. The LO feature is an optional capability for severe operating conditions, not a requirement for normal service.

What is the maximum misalignment angle for GE...LO bearings?

GE...LO bearings can accommodate angular misalignment up to 6 degrees between the shaft and housing. Exceeding this limit can cause edge loading and reduce bearing performance and service life.

Shaft hardness

Recommended shaft hardness is 58-62 HRC with surface roughness Ra ≤ 0.4 µm for optimal PTFE composite performance.

Housing bore tolerance

Recommended housing tolerance is H7 for standard applications. Ensure bore is free of burrs and sharp edges.

Lubrication compatibility

PTFE composite is compatible with most automatic transmission fluids. Avoid solvents and aggressive chemicals that may damage the PTFE layer.

Storage

Store in original packaging in a clean, dry environment. Avoid exposure to dust and contaminants that may embed in the PTFE surface.
