Split Outer Ring With A Compact Inner Ring

The CRBC series crossed roller bearings, manufactured by AUBEARING, feature separable outer rings and integral inner rings designed for high rotational precision applications of the inner ring. Rollers are positioned between the inner and outer rings with spacers to prevent friction, thereby reducing rotational torque resistance. AUBEARING offers six types of crossed roller bearings (equivalent to IKO, cross-referenced interchangeably), including split outer ring type (CRBA), split inner ring type (CRBB), high rigidity type (CRBC), split outer ring type with mounting holes (CRBD), high rigidity type with mounting holes (CRBE), and customized type (CRBX). Among these, the CRBC series of crossed roller bearings are characterized by high rigidity and are the thinnest in their class because of the segmented outer ring, while the inner ring remains integral.

Size range: id 50 - 200mm , OD 66 - 226mm.Features: Suited for applications that have a compact design and require lightweight of the bearings.CRBS series of AUB crossed roller bearing is consisted of an outer ring and an iner ring with a group of cylindrical rollers and spacers(or cages). The rollers are arranged bettveen the inner ring and the outer ring, and spacers are placed between the rollets to prevent them from colliding with each other.

The RA series crossed roller bearings consist of an outer ring and an inner ring, with cylindrical rollers and separators (or retainers) positioned between them to prevent mutual contact. The RA series is a compact type of bearing that reduces the thickness of the inner and outer rings to the limit, derived from the RB series. The extremely small cross-sectional area of RA series crossed roller bearings makes them suitable for lightweight and compact applications, such as rotating parts in robots and manipulators. Manufactured by AUBEARING, the RA series crossed roller bearings are available in two types: RA (open type) and RA-UU (double-sealed on both ends).

The RB series crossed roller bearings feature an integral inner ring and split outer ring design (without mounting holes), maximizing space savings and ideal for applications requiring high inner ring rotational precision. Comprising an outer ring, an integral inner ring, cylindrical rollers, and separators (or retainers), the RB series arranges rollers between the inner and split outer rings with separators to prevent mutual contact.
