CRBT 1005 crossed roller bearing belongs to large‑bore ultra‑thin crossed roller bearing series. It keeps ultra‑slim sectional dimension while realizing large bore size, bears radial, axial and overturning‑moment loads simultaneously. Mainly used for large compact rotary supports, special automation rotary tables and high‑end precision mechanical rotary assemblies.

CRBT series crossed roller bearings are ultra-compact, ultra-thin lightweight crossed roller bearings with integral inner and outer rings. Cylindrical rollers are arranged alternately at 90°, enabling a single bearing to simultaneously support radial loads, bidirectional axial loads, and tilting moment loads. Compared with the CRBS (RA type), the thickness is significantly reduced with a cross-section width of only 5mm, offering lighter weight, minimal space occupation, and ultimate lightweight construction.

The raceways are manufactured with ultra-precision grinding, achieving accuracy grades up to P4/P2, with controllable rotational clearance and stable friction torque. Rigidity is superior to thin-section ball bearings of the same size. Materials are available in GCr15 bearing steel or 440C stainless steel, with open or sealed configurations.

Widely used in small collaborative robot joints, humanoid robot gimbals, medical imaging equipment, miniature harmonic drive modules, surveillance turntables, precision inspection instruments, and other compact, lightweight precision rotating mechanisms. They are ideal as core support bearings for miniature, high-precision, compact equipment.
