the roller is also equipped with a support pad

Crossed roller bearings are mainly two categories, one category is crossed Cylindrical roller bearing  Cross Tapered Roller Bearings
While the other is a cross-tapered roller bearings, both of which are rolling in the V-shaped grooves perpendicular to each other, the only difference is the crossed tapered roller bearing rings V-groove tapered roller according to adopt a different perspective and different , so that a greater capacity, higher speed. Currently on the market, capable of producing cross-tapered roller handful of companies, foreign countries such as Timken, SKF, URB and NACHI bearings, several well-known companies, and there is no domestic production are relatively mature technologies and businesses.

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 bearing effective 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.
