Compatible Assemblies: Drive axle planetary gear shaft assembly, planetary carrier bearing bore
Matching Parts: 360-2334 YM sleeve, 8T-4125 elastic retaining ring, M10×1.25 bolts (2 pieces)
Installation and Fitting Points:
Clean the bearing housing bore and shaft diameter, ensuring no burrs or oil contamination. Shaft diameter surface roughness Ra≤0.8μm, bearing housing bore Ra≤1.6μm.
Cold press installation, pressure ≤20kN. Use a special guide sleeve to ensure coaxiality. Do not strike the end faces.
After installation, check the inner hole roundness ≤0.02mm, cylindricity ≤0.03mm, and parallelism of both end faces ≤0.05mm.
Clearance with planetary gear shaft: 0.040-0.060mm. No abnormal temperature rise during operation (≤60℃).
