5J-1446: Bearing-Aligning

CAT 5J-1446 is a Caterpillar spherical plain bearing, suitable for heavy-duty equipment hinge joints. It automatically compensates for misalignment between the shaft and bearing housing. Key information is as follows:

Key Parameters
Item Details
Type: Spherical plain bearing (self-lubricating), suitable for radial + bidirectional axial loads, used for heavy-duty support at hinge points, compensates for ±2°-3° angular deviation, suitable for off-center loading conditions (Cat® Parts)
Dimensions (Metric/Imperial): Inner diameter 57.30mm (2.26in), Outer diameter 90.50mm (3.56in), Width 38.10mm (1.50in), suitable for corresponding Cat® equipment journals and mounting holes (Cat® Parts)
Material: Bearing steel outer ring + bronze alloy inner liner, inner liner contains solid lubricant, outer ring is hardened to HRC60-64, fatigue-resistant and wear-resistant, suitable for heavy-duty impact conditions
Lubrication Featuring a built-in lubrication groove, suitable for grease lubrication, and lined with solid lubricant, Cat® Parts can operate for short periods in oil-free conditions, meeting the lubrication needs of heavy equipment operating for extended periods. Accuracy: Inner diameter tolerance ±0.01mm, outer diameter tolerance ±0.01mm, spherical roundness tolerance ≤0.005mm, ensuring accurate contact with journals and smooth operation. Suitable for: Articulated arms, hydraulic cylinder lugs, connecting rod joints, etc., of Cat 825G/825H/826G/826H road rollers, some loaders, and bulldozers, used to withstand heavy loads and impact vibrations during compaction and loading operations, ensuring equipment operational stability.

Suitable for harsh working conditions such as mining and infrastructure, adapting to low-speed, heavy-load articulated drive requirements, extending the service life of articulated components.

Performance Characteristics: The spherical self-aligning design automatically compensates for misalignment between the shaft and bearing housing, improving off-center load resistance by approximately 50% compared to ordinary bearings. Suitable for Cat® Parts applications involving high-frequency off-center loads in heavy-duty equipment articulations.

The bronze alloy liner with solid lubricant provides fatigue and wear resistance, extending the lifespan of ordinary carbon steel bearings by approximately 60%, making it suitable for long-term use under harsh conditions.

Lubrication grooves facilitate maintenance, reduce frictional loss, improve articulation flexibility, and lower equipment energy consumption.
