RW High-Performance Crossed Roller Bearings (Integral Inner and Outer Rings, with Mounting Holes)

The RW type crossed roller bearing features an integrated inner and outer ring construction, achieving high component rigidity. Mounting bolt holes are machined on both the inner and outer rings; their dimensions and quantity are optimized to effectively reduce rolling surface deformation during installation, thus ensuring stable rotational performance. Furthermore, by improving machining precision, this product meets high rotational accuracy requirements.

Bearing Features:
·Miniaturization and High Rigidity: Small-diameter rollers arranged in a double-row configuration at 45° intervals achieve miniaturization and high rigidity.
·High Rotational Accuracy: The integrated inner and outer ring structure enables high-precision rotational motion.
·Reduced Installation Time: Mounting holes on both the inner and outer rings facilitate direct fixing, significantly reducing installation time for shafts and support housings.
