CAT 6J-5383 is a Caterpillar radial spherical self-aligning bearing, suitable for heavy-duty articulated parts such as bulldozer booms. It allows for a certain degree of angular misalignment and absorbs vibration and shock. Key information is as follows:
Key Parameters
Item Details
Type: Single-row self-aligning roller bearing, spherical outer ring, double raceway inner ring, with cage, allows ≤2° angular misalignment, adaptable to shaft and housing bore installation deviations
Dimensions (Metric/Imperial): Inner diameter 95.25mm (3.750 inches), outer diameter 165.10mm (6.500 inches), width 40.00mm (1.575 inches), weight approx. 0.86kg (1.90 lbs)
Material: Bearing steel (AISI 52100), inner and outer rings carburized and quenched HRC60-64, rollers HRC62-66, cage is stamped steel plate, grease chamber is compatible with lithium-based grease
Accuracy: Inner diameter tolerance + 0.015/-0.010mm, radial clearance 0.05-0.12mm, suitable for clearance compensation requirements under heavy-duty conditions.
Sealing: Outer ring with nitrile rubber (NBR) contact seal, IP54 protection rating, operating temperature -40℃ to 120℃.
Suitable Scenarios: Suitable for Cat D6H/D6M/D6N/D6R bulldozer boom articulated shafts, 3116/3306 engine accessory drive shafts, etc., used to absorb angular deviations and vibration impacts during operation, ensuring smooth operation under heavy-duty conditions.
Suitable for replacement during equipment overhaul/maintenance when bearings exhibit roller pitting, cage damage, or seal failure.
Performance Characteristics: Spherical design compensates for installation errors and shaft deflection, reduces edge stress, extends bearing life, and is suitable for dusty and high-vibration conditions.
Double-row symmetrical roller distribution ensures uniform load bearing capacity, strong radial load capacity, and can withstand impact loads and bidirectional axial loads.
The sealed structure effectively prevents dust and moisture from entering, reduces the risk of grease contamination, and decreases the frequency of maintenance.
