TAROL units (Tapered Roller Bearings) are double row tapered roller bearings that are supplied with factory-set clearance, greased and sealed. The TAROL units are thus supplied ready-to-fit and are pressed onto the shaft journal by means of a hydraulic unit.
TAROL units are used as wheelset bearing supports on rail vehicles such as goods wagons and passenger carriages. They can be mounted quickly and easily: The bearing is pressed onto the shaft journal in a single operation and is secured by additional parts and bolts. Due to the press fit of the unit on a shaft journal of a diameter within the specified tolerances, the bearing support achieves the necessary axial clearance.
