Matching Parts: 008-0465 Bushing, mounting block, guide sleeve, dust ring

Installation and Maintenance Points
Clean the seat hole and shaft diameter, removing burrs and oil stains. Seat hole roughness Ra≤1.6μm, shaft diameter roughness Ra≤0.8μm.

Use a special press to smoothly press the bushing into the seat hole. Do not strike the bushing end face. Ensure the bushing end face is flush with the seat hole end face.

Post-installation inspection: Bushing inner diameter roundness ≤0.02 mm, coaxiality ≤0.03 mm, no jamming or misalignment.

Maintenance: Check bushing wear every 2000 working hours. Replace when inner diameter wear exceeds 0.2 mm. Avoid direct contact between the shaft and the bushing steel back.
