This superior performance allows it to have no difficulty in installation and is very easy to achieve with better rotation and torque. The outer ring and inner ring are rotatable and you can rotate it to where you want it to be used. RU cross roller bearings, inside the roller is also cross arranged, which has a certain space, to prevent roller slide out. This design is to allow the bearings to withstand greater pressure, the load can be divided evenly.

RU cross roller bearings, in addition to better rotary accuracy, can also withstand greater pressure. It is a kind of mechanical parts made by special steel, very hard, work ability is very high, at a temperature greater pressure on the environment; light hardness is not enough, some degree of flexibility is also essential, such use will have to ease the pressure of pressure space, not bad. RU cross roller bearings simple installation design, designed for all walks of life, so that your installation becomes simple.

Type RU (internal and external ring type)

Since the mounting holes have been installed, no fixed flanges and support seats are required. In addition, due to the integration with belt the inner and outer ring structure, the installation has no effect on the performance of almost, so it can obtain stable torque and rotation accuracy. Can be used for outer and inner ring rotation.
