The CAT 5T-6062 is a Caterpillar original flange bearing end cover, mainly used for positioning and sealing bearings at the gearbox, hydraulic pump, or drive shaft end of equipment such as excavators and loaders. It is compatible with rolling bearings with a shaft diameter of φ40 mm (such as model 6208) and has both axial fixation and anti-chip functions. The following is professional structured information:
Core Technical Parameters (Professional Version)
Item Details
Basic Attributes
Model: 5T-6062, Flange-type Bearing End Cover, Single Weight: 0.85 kg, Quantity: 1 piece per unit, Material: Q235 low carbon steel, stamped and formed, surface galvanized and passivated, Suitable for φ40 mm shaft diameter bearings, Operating Temperature: -40℃ to +120℃
Key Dimensions
Bearing mounting hole inner diameter: φ40 mm (tolerance +0.020/+0.040 mm), End cover outer diameter: φ75 mm, Flange diameter: φ90 mm, Flange thickness: 8 mm, End cover height: 25 mm, Mounting holes: 4×φ10 mm (evenly distributed, hole spacing: φ80 mm), Stop diameter: φ65 mm (tolerance -0.010/-0.030 mm)
Material and Process
Steel plate thickness: 5 mm, galvanized layer thickness: ≥8 μm, Salt spray test: ≥48 h, flange face flatness ≤0.1 mm, mounting hole chamfer C1.5 mm, bearing hole inner surface roughness Ra≤1.6 μm
Performance Parameters: Rated axial load 15 kN, sealing groove compatible with φ65×φ75×5 mm O-rings (nitrile rubber NBR), protection rating IP54 (dustproof, splashproof), bolt tightening torque 25–30 N・m (compatible with M10×1.5 bolts)
Compatible Models: Excavator 320GC/323GC, Loader 950M/966M, compatible bearing model 6208 (inner diameter φ40 mm, outer diameter φ80 mm, thickness 23 mm), common installation locations are gearbox output shaft end, hydraulic pump drive shaft bearing cover, pilot pump flange end cover
Installation and Maintenance Points: Before installation, clean the bearing housing hole (free of burrs/scratches), end cover flange surface, check the O-ring for damage, and apply a small amount of Cat 5P-0960. Grease is applied to the O-ring surface to ensure a good seal.
Positioning Requirements: The end cap stop and bearing housing bore should have a transition fit (H7/h6). The flange face should be flush with the bearing housing (clearance ≤0.05 mm). Bolts should be tightened diagonally in two stages (torque 25–30 N·m) to prevent uneven loading that could lead to seal failure.
Maintenance Requirements: Check the end cap tightness every 1000 hours. If leakage occurs, replace the O-ring and retighten the bolts. If the end cap is deformed (flatness > 0.1 mm), it needs to be corrected or replaced.
Troubleshooting: If the bearing bore is worn (≥0.1 mm), replace the end cap and repair the shaft diameter (chrome plating/spraying). If the O-ring is aged, it is recommended to replace it every 2000 hours.
