URB and NACHI bearings, several well-known companies

XRT Series Cross Tapered Roller Bearings Introduction cross roller bearings are mainly two categories, one category is crossed cylindrical roller bearings, and the other is a cross-tapered Roller bearing  both of which are rolling in the V-shaped groove on perpendicular to each other, the only difference is the crossed tapered roller bearing rings V-groove angle is not the same. 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, while domestic production of the current technologies are relatively mature and only PRS. Cross tapered roller bearings (XRT series) is designed to provide a small space in a high rotation accuracy and stiffness, 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.
