RCJTZ40 INA bearing unit

INA RCJTZ40 Flanged Bearing Unit

The INA RCJTZ40 is a premium 2-bolt oval flanged bearing unit engineered for the stable support of 40 mm diameter shafts. It features a robust gray cast iron housing paired with a self-aligning insert bearing. A standout design feature is the spherical interface between the bearing and the housing seat, which allows for angular self-alignment. This capability enables the unit to automatically correct shaft misalignments, preventing internal stresses and significantly increasing the operational lifespan of your machinery.
