Matching Parts: 583-5034 YM sleeve, 8T-4125 elastic retaining ring, φ80mm pin, M12×1.75 bolts (2 pieces)
Installation and Fitting Points:
Clean the earring seat hole and pin, ensuring no burrs or oil contamination. Pin surface roughness Ra≤0.8μm, seat hole Ra≤1.6μm.
Cold press installation, pressure ≤25kN. Use a special guide sleeve to ensure coaxiality. Do not strike the end face.
After installation, check inner hole roundness ≤0.02mm, cylindricity ≤0.03mm, and parallelism of both end faces ≤0.05mm.
The clearance between the pin and the earring seat is 0.050-0.070mm, the interference fit of the earring seat hole is 0.018-0.028mm, and there is no jamming during swing.
