AXCR cross roller bearings consist of an inner and outer ring, cylindrical rollers and spacers. Due to their compact size, these bearing types are frequently used as swivel bearings. Typical applications are milling heads, swivel axes or robots, but also industrial applications with increased accuracy requirements.
In cross roller bearings, the cylindrical rollers are arranged cross-wise in a raceway offset by 90° so that loads and torques can be evenly absorbed in all directions.
Cross roller bearings offer relatively high axial and radial rigidities and tilting rigidity in highly compact constructions.
Designs
Cross roller bearings are available in a multitude of bearing types and designs. Basically, we differentiate between these as follows:
■ Single-part rings with radial filling plugs for filling with rollers and spacers
■ Two-part, non-rotating ring, single-part rotating ring
■ Screw-on rings / non screw-on rings
■ Special bearings with customer-specific ring dimensions, fastening options or toothings
