Product Description
RU series cross cylindrical roller bearings (inner and outer rings integral, with mounting holes)
This series models do not need fixed flanges and supports because of the machining of mounting holes.In addition, the installation has little impact on performance due to the use of integrated inner and outer ring structure with seat, so stable rotation accuracy and torque can be obtained.Can be used for outer ring and inner ring rotation.
Structure features: cross roller bearing, cylindrical roller in the 90 degree v-groove rolling surface through the isolation block is arranged vertically, so cross roller bearing can withstand radial load, axial load and torque load and other multi-direction load.The size of inner and outer ring is miniaturized, and the extremely thin form is close to the limit of the small size, and has high rigidity, and the precision can reach P5, P4, P2.Therefore, it is suitable for industrial robot joints and rotating parts, rotating table of mechanical processing center, precision rotating table, medical machine, calculator, military industry, IC manufacturing device and other equipment.
Rotation accuracy: there is an isolation block between the vertically arranged rollers in the bearing, which prevents the inclination of rollers and the friction between rollers, and reduces the rotation torque.In addition, compared with the previous use of steel plate retainer, there will be no roller contact or locking on one side.At the same time, because the inner (or outer) ring is a two-division structure, bearing clearance can be adjusted, even if the preload is applied, but also can obtain high precision rotation motion.
Usage features: the divided inner ring (or outer ring) is fixed together with the cross roller shaft ring after loading roller and interval retainer to prevent separation, so it is easy to install the cross roller shaft ring.Through the spacer retainer, the friction between rollers is eliminated, and the roller side is prevented from falling, so that the stable rotation torque can be obtained.Because the rollers are arranged in a cross arrangement, so only one set of cross roller bearings can bear the load in all directions, compared with the traditional model, the rigidity is increased by 3-4 times.
