The angle between the bearing and the tapered geometry


High rotational accuracy and rigidity, substantial savings in material costs. Such bearings are the two bearing raceways and rollers are mounted together at right angles to the cross, the adjacent rollers in the opposite direction, the roller is mounted between the rollers and the spacers, the roller is also equipped with a support pad , which makes the rollers into two halves of the column volume within the same space. The angle between the bearing and the tapered geometry is such that the tapered bearinge ffective span than the actual width of the bearing itself several times.
XRT Series Cross tapered roller bearings for high-speed machine tool applications, such as vertical boring machine and vertical grinder. Also particularly suitable for many space is limited, high precision rotating equipment Series has two tapered roller at 90 ° to the surface of the V-cutter vertical cross through a spacer retainer arrangement, able to withstand the radial load, axial load and other loads in all directions.
Raceways and rollers on the line contact structure provides maximum rotational accuracy, high stability and greater tilt stiffness.
Preload adjustable design extends bearing life, the maximum extent possible to increase the rigidity and provides a minimal beat.
Nylon spacer lower inertia, running less torque.
Components using surface-hardened steel or bearing steel electroslag remelting, good impact resistance
