CASE Pins, Bushes & Bearings Parts

BUMA injects durability genes into high-load motion mechanisms. Micron-level tolerance control ensures seamless engagement between the pin and the shaft hole; multi-layer plated bushings simultaneously optimize the pressure distribution on the bearing surface; high-temperature bearing alloys eliminate eccentric load stress. Abnormal vibration and eccentric wear are reduced, and precise force transmission is maintained during complex actions such as digging, lifting, and rotating, greatly reducing full-cycle maintenance costs.
