NSK Cross Roller Slewing Ring Bearing

NSK Cross Roller Ring is a roller bearing with high rotation accuracy capable of bearing loads in every direction. Because it has orthogonally arranged cylindrical rollers, it can bear loads in every direction.As their name suggests, crossed roller slides (also referred to as crossed roller bearings) are linear bearings that use cylindrical rollers—as opposed to balls—to carry a load. The rollers ride between parallel guides in which v-shaped grooves have been ground.It is equipped with inner ring and outer ring, inner ring and outer ring form between assembling on the slideway of roller, the bearings are characteristic of their in two pieces of fission structure, through the screw connection, inner ring side face higher than the outer end face on the same side, outer ring along the circumferential uniform axial connection hole, on the slide along the circumferential uniform roller are arranged cross, between each roller set column spacing block.The two ends of the cylindrical isolation block are provided with arc-shaped grooves, and the arc-shaped grooves on the two ends are in the shape of a cross in the radial direction.The cross section of the slide between the inner ring and the outer ring is square.
