IKO cross roller bearings for the inner and outer rings integrated structure

Inner and outer rings are integrated structure (non-split), with the mounting holes on the inner and outer rings can be easily installed on the device. In addition, less susceptible to such a shaft hole and the surrounding structure of the plate, to achieve a high rigidity, high precision guide. Crossed roller bearings are orthogonal collocation between the inner and outer roller, is a compact structural bearings. Rolling surface for the line contact, thus bearing load caused by the elastic displacement is extremely small, and can also carry radial load, axial load and moment other complex loads.
This section requires small bearings are widely used in high rigidity and high rotational accuracy of industrial robots, machine tools and medical equipment such as rotating parts.
Crossed roller bearings with cages and supplied splitter and full roller way.
With a holder and with the separator for high speed friction coefficient of the site, full roller suitable for low-speed heavy-duty area.Crossed roller bearings between the inner and outer rings orthogonal collocation roller, is a compact structural bearings. Rolling surface for the line contact, thus bearing load caused by the elastic displacement is extremely small, and can also carry radial load, axial load and moment of complex joint load.
Such bearings are widely used require small high rigidity and high rotational accuracy of industrial robots, machine tools and medical equipment such as rotating parts.
Crossed roller Backing bearings with cages, with spacers and full roller type, and other structures, rich variety series complete with cages and supplied splitter is suitable for high speed friction coefficient of the site, full roller suitable for low-speed heavy-duty area. Cross cylindrical roller bearings are sealed on the bearing side with special synthetic rubber seals, for dust and grease leakage excellent sealing effect.
1 Structural features: cross roller bearings, cylindrical roller is at 90 ° to the surface of the V-shaped groove rolling through the isolation blocks are arranged perpendicular to each other, so the cross roller bearings can bear radial load, axial load and torque load and other multi-directional load. Inside and outside the ring size is small, thin form is close to the limit of small size, and has high rigidity and precision can reach P4, P2 class. Therefore suitable for industrial robot joints and rotating parts, machining centers rotary tables, robots rotating part, precision rotary tables, medical equipment, calculators, IC manufacturing equipment and other equipment.
(2) rotating accuracy: the bearing arranged vertically with spacers between the rollers to prevent the inclination of the rollers and friction between rollers, reducing the rotational torque. Further, compared to the previously used steel retainer, does not occur in one contact of roller or seize. Meanwhile, due to inner or outer ring is two split bearing clearance adjustable, even if they are applied preload can be obtained with high precision rotary motion.
