SXU Crossed Roller Bearings SXU crossed roller bearings are specifically designed for high-precision rotary systems,featuring an integral inner ring,split outer ring,and 90° orthogonal "X"-shaped cylindrical roller arrangement.They are applied in Heavy-Duty, Industrial Robots,Large Precision Rotary Tables,Specialized High-Precision Machinery. High Rigidity:The crossed-roller layout increases the anti-deformation ability by 3 - 4 times (compared with traditional bearings). Long Life:The surface hardening treatment of GCr15 material increases the fatigue life by 30%.

Roller Arrangement and Load Distribution: The rollers are arranged orthogonally to form an "X"-shaped contact line,evenly dispersing radial and axial forces. Moment loads are transmitted through the diagonal contact of the rollers,reducing local stress concentration. Lubrication and Sealing:Grease Lubrication:Krytox® lubricating grease is suitable for high-temperature or vacuum environments. Oil Lubrication:A circulating oil system is used for ultra-high-speed or heavy-load scenarios. Sealing Design:The double-seal (UU/U) protects against the intrusion of dust and liquid. Thermal Management:The low-friction design reduces temperature rise,meeting the thermal stability requirements of precision instruments.
