JRT Basic Series

JRT bearings with thrust centripetal structure are double direction thrust bearing mounted and guided with bolt, bearings have preload before leaving factory, and there is no need to adjust clearance when installed. This series of bearings have characteristics of high stiffness, good bearing capacity and running accuracy, and can withstand the bidirectional axial load, radial load and tilting moment. The series is applicable to the place with low speed and short operation cycle.
