9J-1433: Four Mounting Holes 35mm Steel Bearing Cap

The Cat 9J-1433 is a Caterpillar steel bearing cap with four mounting holes. Its core function is to seal and secure bearings, suitable for heavy-duty machinery transmission systems. Below is complete core information:

Core Parameters (Precise Version)

Item Details
Basic Information: Model 9J-1433, type is a steel bearing cap with four 35mm diameter mounting holes for sealing and positioning the bearing ends, preventing dust and impurities from entering, securing bearing assemblies, suitable for heavy-duty applications.

Compatible Models: Suitable for transmission components such as gearboxes, drive axles, and differentials in Cat 3406 series engines, D8L/D8N bulldozers, 777 mining trucks, 627E loaders, etc. Commonly used to secure the ends of cylindrical roller bearings and tapered roller bearings.

Material and Process: Material is 45# high-quality carbon steel, quenched and tempered, hardness HRC40-45, surface sandblasting for rust removal + anti-rust primer + topcoat, sealing surface precision… Ra≤0.8μm, Mounting hole tolerance H7
Key Dimensions: Inner diameter approx. 100mm, outer diameter 145mm, thickness 28mm, mounting hole diameter 35mm, hole spacing (diagonal) 120mm, bolt countersunk depth 10mm, chamfer radius 1.5mm, weight approx. 3.2kg
Compatible Components: Compatible with bearing assemblies such as 177-4143 inner ring and 177-4144 outer ring. Matching bolts are 10-3222 (M16×60mm). It is recommended to use a sealing gasket (model 9J-4984) for improved sealing.
Function, Installation, and Maintenance Points
Core Functions: Seals the bearing cavity to prevent impurities from entering and to prevent grease leakage; axially positions the bearing, suitable for heavy-load and high-vibration conditions, ensuring stable operation of transmission components.

Installation Points: After cleaning the sealing surface, install the sealing gasket and tighten the bolts evenly diagonally (torque 65-75 N·m). Over-tightening is prohibited. After installation, there should be no leakage, and the radial runout should be ≤0.1 mm.

Maintenance Points: Regularly check the bolt tightness and sealing condition. Replace the bolts promptly if leakage or deformation is found to prevent bearing failure due to contamination or poor lubrication.
