Types and types of crossed cylindrical roller bearings

The design of XRT series cross roller bearings can provide high rotational accuracy and stiffness in a small space, and greatly save material costs. In this bearing, two groups of bearing races and rollers are installed at right angles, with adjacent rollers facing in opposite directions, gaskets installed between the rollers, and support washers installed on the rollers, so that two rows of semi-rollers can be accommodated in the same space. The included angle and conical geometry of the bearing make the effective span of the bearing several times larger than the actual width of the bearing itself.

XRT series bearings are suitable for high-speed machine tool applications, such as vertical boring machines and vertical grinding machines. It is also especially suitable for many devices with limited space and high rotation accuracy. Inside diameter 10 1.600 mm to 2463.800 mm (4.000 inches. To 97,000 inches. )

The outside diameter is 279.400 mm to 28 19.400 mm (1 1.000 inch). To 1 1.000 inch. ). XRT series has two rows of tapered rollers arranged 90 degrees vertically on the V-shaped hob surface, which can withstand pressure.

The linear contact between raceway and roller structure provides maximum rotation accuracy, high stability and greater tilting stiffness.

The adjustable design of preload prolongs the bearing life, maximizes the stiffness and provides the minimum runout.

Nylon gasket has low inertia and low running torque.

Parts are made of surface carburized steel or electroslag remelting bearing steel, which has good impact resistance. Precision rotary indexing table for machine tools
