High Precision Top Grade High Speed Cross Tapered Roller Bearing XR766051

Features and applications

Crossed taper roller bearings are designed to offer the highest levels of rotational accuracy and rigidity while conserving space and saving material costs. The bearing features two sets of races and taper rollers brought together at right angles with alternate taper rollers facing in opposite directions, and with nylon separator between the taper rollers to avoid the the mutual friction between rollers and the overturning effect. And reduces the rotation torque, and that can bear combined loads of radial loads, axial loads and overturning moments.

The bearings adopted the design of large cone angle and taper, which make the bearing complement have larger strided distance, The extension line intersecting point of the raceway of taper roller is located on the rotation middle line of the bearing, which make the taper roller to make pure rolling when working, avoided the relative glide with the raceway, so the limited speed is much higher than the crossed roller bearing, and the friction torque is also lower than that.

Crossed taper roller bearing features:

1. High precision: precision at P4, P4, P2.

2. High rigidity: these series bearings are with preload.

3. High load capacity: can support radial load, axial load, and tilting load.

4. High speed: rollers rolling in the raceway, so the limited speed of crossed taper roller bearings is higher than that of crossed cylindrical roller bearings.

5. Low friction: the frictional torque of crossed taper roller bearings is much lower than that of crossed cylindrical roller bearings.

Application:

This make the bearings suited to applications where space is limited or the lowest possible center of gravity of a rotating mass is required and high speed. And withstand high overturning moments, for example, accuracy machine tools circular division rotary table, vertical and horizontal boring machine, vertical grinder, rotary surface grinding machine, vertical lathe, large-scale gear hobbing machine, turret, large telescope (radio telescope and optical telescope), rotation camera, industry robot.
