Home > Ultra-precision bearings > Cylindrical Roller Bearings

BRZB super-precision cylindrical roller bearings have below major characteristics that set them apart:
·High rigidity
·High limiting speed
·Low friction
·Align-able tolerance.

These bearings are therefore particularly well suited for machine tool spindles where the bearing arrangement must accommodate heavy radial loads and high speeds, while providing a high degree of stiffness.
BRZB single-row super-precision cylindrical roller bearings excel in high-speed applications, while their double-row variants are better suited for handling heavier radial loads.
