Precision Crossed Roller Bearings for Harmonic Drive Gearboxes

Skeye Machinery｜Harmonic and RV Reducer Bearing Series Introduction

Reducer bearings are mainly used in harmonic and RV reducers, divided into rigid and flexible bearing types. Rigid bearings feature crossed cylindrical rollers, offering high rigidity, load capacity, and positioning accuracy. Depending on installation requirements, they come in various structures such as integral inner rings, split outer rings, or fully integral rings. Flexible bearings have thin walls designed to deform elastically in cooperation with harmonic drive cams, mainly bearing alternating stresses, suitable for high-precision and space-limited applications.

Bearings for RV reducers require high rigidity, low backlash, and stable torque transmission. Precise axial preload adjustment during installation is critical to achieving high output accuracy and long-term stable operation. Their compact structure, low inertia, and quick response support high-speed acceleration and deceleration demands, making them key components for reducer performance.

This bearing series is widely applied in robot joints, precision positioning platforms, automation equipment, machine tools, aerospace, and military industries. Customized designs and prototype development are available to meet the needs of applications requiring both high performance and limited space.
