Use of slewing bearing crossed roller bearings
- Sep 06, 2018 -

Rotary crossed roller bearings, the rollers of which are arranged at right angles to each other at intervals between the inner and outer wheels. They can simultaneously withstand loads from all directions (such as axial thrust or momentum load) due to the roller and track surface contact. Therefore, the possibility that the slewing bearing is elastically deformed by the load is small. This type of slewing bearing is widely used in applications such as industrial robots, work machines and medical facilities, and requires high rigidity, and can ensure precise conditions at close and high speeds.

 In the slewing cross roller bearing, since the cylindrical rollers are arranged perpendicularly to each other by the spacers on the v-shaped groove rolling surface of 90°, one cross roller bearing can bear the radial load and the axial direction. Load in all directions, such as load moment load. The size of the inner and outer rings is miniaturized to a minimum. The extremely thin type is a small size close to the limit and has high rigidity. Therefore, it is most suitable for industrial machines to recognize joints or rotating parts, rotary tables for machining centers, and robots. Rotating part, precision rotary table, medical equipment, meter. Uses such as IC manufacturing equipment.
