The 4.457 Eccentric Adjustable Bearing is a precision-engineered combined radial-axial component, specially designed for low-speed, high-load applications across material handling, construction, and automation industries. Boasting an inner diameter of 40 mm, outer diameter of 77.7 mm, and width of 54 mm, it delivers a dynamic radial load capacity of 48 kN and axial load capacity of 18 kN, with a maximum speed rating of 800 RPM.

Its unique eccentric adjustment mechanism (adjustment range: 29–30.5 mm) enables micro-tuning to compensate for installation misalignment, effectively reducing vibration, noise, and premature wear in equipment such as forklifts, conveyors, gearboxes, and agricultural machinery.

Crafted from hardened 20CrMnTi (outer ring) and Gcr15 (inner ring), this bearing achieves a hardness of 58–62 HRC, ensuring exceptional rigidity, wear resistance, and long-term operational reliability.

The 4.456 and 4.457 eccentric adjustable bearings share identical core dimensions except for total height and mounting height.
