Cross roller bearings, the rolling element is generally Cylindrical roller or tapered roller, the rollers are arranged so that they Cross between the inner ring and the outer ring., and is maintained between the Isolation blocks. The bearing has high rotational accuracy, larger carry Capacity, smaller size and higher speed of rotation and higher rigid, with the absolute Advantages and more widely applications compared with other bearings.
the criss-cross arrangement of the roller structure makes Individual bearing can carry axial load, radial load and overturning moment in All directions. Compared with the traditional structure, the bearing rigidity is 3-4 times of that of traditional bearings. and the size of the bearing is close to the limit of ultra-thin of the structure, and has high rigidity. It is well Apply to the joints or rotating parts of industrial robots, the rotation of the Machining center, robot rotation parts, precision rotary table, medical Equipment and other applications.
Crossed tapered roller bearings with large cone angle and cone Geometric design enables the bearing overall effective span to be bigger, while Also saving space, saving material costs. Therefore, the cross-tapered roller Bearings have a higher overturning moment capacity, higher rotation accuracy and higher limit speed, is the ideal choice for high-speed vertical lathe, Vertical boring machine, and vertical grinder.(HONBbearing05)
