RCJTZ20 INA bearing unit

INA RCJTZ20 Flanged Bearing Unit

The INA RCJTZ20 is a premium 2-bolt oval flanged bearing unit engineered for the precise support of 20 mm diameter shafts. It features a compact gray cast iron housing paired with a self-aligning insert bearing. The spherical design of the bearing’s outer ring allows for angular self-alignment, enabling the unit to automatically correct shaft misalignments and prevent detrimental internal stresses.
