Cross Tapered Roller Bearings XRT220-NT Bearing 580x760x80mm

XRT series of bearings for high-speed machine tool applications, such as vertical boring and vertical grinders. Many are also particularly suitable for limited space, rotary high precision equipment.

XRT series has two tapered roller surface in a V-type cutter by 90 vertically staggered spacing can withstand the load in all directions radial load, axial load and the like. Raceways and rollers on the sub-structure of the line contact provides maximum rotational accuracy, high stability and greater tilt stiffness. Preload adjustable designed to extend bearing life, the maximum increase in the stiffness and provides minimal beat. Nylon spacer lower inertia, the smaller running torque. Components using surface-hardened steel or good ESR bearing steel, impact resistance

`Precision tapered roller bearings are mainly used in machine tool spindles, precision planetary reducer. Chuck, top cutter need while bearing axial load, radial load and overturning moment for occasions.
