The CRBTF Series Crossed Cylindrical Roller Bearings carry forward the design philosophy of the CRBT series in pursuing ultimate lightweight construction, while retaining mounting holes on both the outer and inner rings.
The CRBTF series is suited for applications with extremely demanding weight and installation space requirements. With the integrated mounting holes, the bearings can be directly bolted to flanges, making installation exceptionally convenient.
Thanks to the crossed roller structure, the CRBTF series still delivers strong load-carrying capacity for axial, radial, and overturning moment loads, along with outstanding rotational accuracy.
The CRBTF series crossed cylindrical roller bearings are well-suited for use in joints and rotating sections of industrial robots, rotary tables of machining centers, rotating parts of manipulators, precision rotary tables, medical instruments, measuring instruments, IC manufacturing equipment, and similar applications.
