Characteristic

The characteristics of compact structure, light weight, steel structure, smooth operation, high precision, safe and reliable, bear the axial force, radial force and overturning moment at the same time, is under heavy load, low speed characteristics, LYDZ crossed tapered roller bearings are widely used in engineering, mining, metallurgy, shipbuilding, port, oil, chemical industry, food, aerospace, military industry, instrument and meter industries.

Cross tapered roller bearing (XRT Series) is designed to provide a relatively small space.

High rotation accuracy and stiffness, substantial savings in material costs. This kind of bearings is the two sets of bearings roll and roller according to the orthogonal cross installed together, the adjacent roller in the opposite direction, between the roller and the roller installed isolation block, roller is also provided with a support pad, which makes the roller two semi column tolerance into in the same space. Bearing the angle and the geometry of the bearing, the bearing is more effective than the actual width of the bearing itself.

XRT series of crossed tapered roller bearing for high-speed machine tool applications, such as vertical boring machine and vertical grinder. Is also particularly suitable for many space limited, high rotation accuracy requirements of the device.


Design characteristics

The XRT series of two row tapered roller in the V - type hob with 90 degrees on the surface of the - type hob, can withstand the radial load, axial load and so on.

The line contact with the roller and the roller is provided with the maximum rotation accuracy, high stability and a greater degree of inclination.

The adjustable design of the pre load can prolong the bearing life, and increase the stiffness and provide the minimum jitter in the maximum.

The inertia of the nylon is lower, and the running torque is small.

Components used surface carburizing steel or electric slag remelting bearing steel manufacturing, good impact resistance.
