CRBE03515A Crossed Roller Bearing

CRBE series cross cylindrical roller bearing (integral inner and outer ring, with mounting hole)

------------------------------------------------------------------------------------------------------------------

Because the mounting holes have been processed for this series, no fixed flanges and supports are required.In addition, due to the use of the integrated inner and outer ring structure with a seat, the installation has little impact on the performance, so stable rotation accuracy and torque can be obtained.Can be used for outer ring and inner ring rotation.

Structural features

------------------------

cross roller bearing, cylindrical roller in a 90 degree v-groove rolling surface through the isolation block is perpendicular to each other, so cross roller bearing can bear radial load, axial load and torque load and other multi-direction load.The size of the inner and outer ring is miniaturized, and the extremely thin form is close to the limit of the small size, with high rigidity, and the accuracy can reach P5, P4, P2.Therefore, it is suitable for the joint and rotary parts of industrial robots, the rotary table of machining center, precision rotary table, medical machines, calculators, military industry, IC manufacturing devices and other equipment.

Rotation accuracy

------------------------

the bearings in the vertical arrangement of the rollers between the isolation block, prevent the roller tilt and mutual friction between the rollers, reduce the rotation torque.In addition, compared with the previous use of plate retainer, roller in one side contact or locking phenomenon will not occur.At the same time, because the inner ring (or outer ring) is a two-part structure, the bearing clearance can be adjusted, even if the preload is applied, can also obtain high precision rotation movement.

Features

------------

the split inner ring (or outer ring) is fixed together with the cross roller shaft ring after loading the roller and spacer holder to prevent separation from each other. Therefore, it is easy to install the cross roller shaft ring.The friction between the rollers is eliminated by the spacer holder to prevent the roller from falling sideways, thus obtaining stable rotating torque.Due to the cross arrangement of the rollers, only one set of cross roller bearings can bear the load in all directions, compared with the traditional model, the rigidity is increased 3~4 times.
