BRS industrial automation bearing mainly refers to crossed roller bearing. Its cylindrical rollers are in cross arrangement and between every two rollers there is a specially designed space retainer to ensure bearing's running accuracy.
Crossed roller bearing has the feature of high rigidity and high precision rotation, which are basic requirements of industrial automation bearings. According to machines' different working conditions, BRS offers a whole set of bearing solution for special requirements like high/low temperature, food grade material, medical equipment, etc.
Based on different structure and performance, BRS Crossed Roller Bearing can be devided into following types:
1. Super high rigidity, both inner ring and outer ring have integrated structure (Inseparable).
2. Outer ring separable & inner ring inseparable structure is the most widely used crossed roller bearing, mainly use for inner ring rotation.
3. High rigidity high rotation accuracy, inner ring separable structure.
4. Super thin series crossed roller bearing.
5. Crossed roller bearing with installation holes.
