GE40ES Spherical Plain Bearing 40×62×28mm Re-lubricatable Steel-on-Steel Self-Aligning Joint Bushing

GE40ES is one of the most popular metric radial spherical plain bearings. The convex spherical inner ring matches concave outer ring, delivering automatic self-alignment for low-speed swing & oscillating motion, effectively compensate shaft deflection and assembly misalignment.

• High heavy & impact load capacity

  Carry large radial load plus bidirectional axial combined shock loads, stable under alternating heavy pressure.

• 7° self-aligning compensation

  Offset installation errors and shaft bending, reduce equipment vibration and component wear.

• Easy re-lubrication design

  Complete oil groove + dual-side lubrication holes, convenient grease refilling to extend service life.

• Wear-resistant hardened steel surface

  Quenched & phosphated contact surface with molybdenum disulfide pretreatment, anti-abrasion for long-cycle swing work.

• Simple press-fit installation

  Compact integrated structure, easy to assemble into housing without extra fixtures.

• Construction machinery: Excavator arm joints, crane connecting rods, loader pivot hinges
• Agricultural machines: Tractor suspension joints, harvester linkages, farming plow swing parts
• Hydraulic equipment: Hydraulic cylinder end lugs, pneumatic swing actuators
• Transportation: Truck suspension linkages, engineering vehicle pivot points
• General industry: Mining equipment, automation swing mechanisms, material handling machines

Designed for low-speed oscillating swing movement, not suitable for continuous high-speed rotation. Reliable operation in dusty, heavy-load normal temperature working environments.
