Cross roller bearings performance
The Structure and Character of Cross Roller Bearing
ZYS precision cross roller bearing, the inner structure of which adopts the vertical and cross arrangement of cylindrical rollers with 90°, can bear radial load, double-direction thrust loads and overturning moment at the same time. Combined with its high rigidity, crossed roller bearing can be applied to the joints and rotating parts of industrial robots, rotary tables of machining centers, rotating parts of manipulators, precision rotary tables, medical equipments, measuring instruments, IC manufacturing machines, etc.ZYS precision crossed roller bearing has three structure types, including bearing with cage, with separator, and with full complement. Cage and separator types are suitable to low friction moment and high-speed rotation, while full complement is suitable to low-speed rotation and heavy load.
ZYS precision cross roller ring has the following seven structure series: RB series, RE series, RU series, RA series, RA-C series, CRB series and CRBH-A series. The precision cross roller ring produced by ZYS has a standard accuracy of ISO4, which is equivalent to ABEC7 of the American Bearing Manufacturers Association. ZYS also provides ISO2 grade crossed roller bearing (equivalent to ABEC9 grade) and P4A grade cross roller rings (dimensional accuracy equivalent to ISO4 grade and rotation accuracy higher than ISO4 grade).
