as domestic cross roller bearing industry leader.

Cross Tapered Roller Bearings is a special cross roller bearings, high precision, high speed, mainly for large equipment manufacturing facilities, which in recent years due to its particularity and other bearings incomparable superiority and is widely be used. Able to produce the current international cross tapered roller bearing manufacturers have more famous Timken, SKF (SKF), NACHI bearings and other famous companies. China currently has a high level of production to achieve import substitution only PRS (Precede bearings). XRT crossed tapered roller Backing bearings  especially in large, extra large cross-tapered roller bearings are the main parts of large equipment, has always been monopolized by foreign bearing companies. The large cross-company 2800mm PRS tapered roller bearings successfully developed and successfully used to break the monopoly of foreign giants, greatly reducing the cost of domestic large-scale equipment and strong support for the domestic industry, the rapid development of large-scale equipment, equipment for the Chinese manufacturing takeoff contribute their meager forces, but also marks the PRS companies to enter the high-end cross roller bearing production fields, as domestic cross roller bearing industry leader.
 XRT Series cross roller bearing design in a smaller space to provide high rotational accuracy and rigidity, a substantial saving 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.
