Cross Tapered Roller Bearings XR496051

in the cross-roller bearings, cylindrical roller due to the 90 ° to the surface of the V-shaped groove scroll through the spacer retainer is arranged perpendicular to each other, so a cross roller angular contact ball bearing can bear radial load, axial load and moment load and other loads in all directions. Inside and outside the ring size is the minimum possible, in particular, is close to the limit of very thin type compact size, and high rigidity, so the most suitable for the industrial robot joints or rotating parts, machining centers rotary table, manipulator rotating parts, precision rotary tables, medical equipment, measuring instruments, IC manufacturing equipment and other purposes. Crossed roller bearings, having been split inner or outer ring, load rollers and spacer retainer after the Cross-Roller Ring and fastened together to prevent separated from each other, so when you install the Cross-Roller Ring Operation easy. As for the cross-roller arrangement, non-standard cross roller bearings, so only one set of Cross Roller Ring can bear loads in all directions, compared to conventional models, rigidity increased by 3 to 4 times. Also, because the cross roller bearing inner or outer ring is two split bearing clearance adjustable, even if they are applied preload can be obtained with high precision rotary motion.
