Timken XR/JXR/PSL 912 Cross Taper Roller Bearings

Cross-tapered roller bearings are designed to provide high rotational accuracy and stiffness in a small space, resulting in significant material cost savings. This type of bearing is to install two sets of bearing races and rollers at right angles. The adjacent rollers are facing in opposite directions. The spacers are installed between the rollers and the rollers. The rollers are also equipped with support spacers. This allows the two halves of the roller to fit into the same space. The angle and tapered geometry of the bearing allows the effective span of the bearing to be several times larger than the actual width of the bearing itself.

Cross tapered roller bearings are suitable for high speed machine applications such as vertical boring and vertical grinding machines. It is also especially suitable for many devices with limited space and high rotation accuracy.

Features:

Two rows of tapered rollers are vertically aligned by a spacer on a V-shaped hob surface of 90°, and can withstand loads in all directions such as radial load and axial load.

Line contact on the raceway and roller construction provides maximum rotational accuracy, high stability and greater tilt stiffness.

The preloaded adjustable design extends bearing life, maximizing stiffness and providing minimum runout.

The nylon spacer has a low inertia and a small running torque.

The parts are made of surface carburized steel or electroslag remelted bearing steel with good impact resistance.
