BSQ JRA Cross Roller Rotary Guide
BSQ JRA is a cross roller rotary guide designed for accurate and rigid rotary motion. Its thin, compact ring structure keeps the overall size small while supporting radial, axial and moment loads.
The JRA uses a split outer ring with a rotating inner ring. Cylindrical rollers are arranged at 90° in a V-groove and separated by spacer retainers. This design helps prevent roller skewing and maintain stable rotational torque.
BSQ JRA is available with inner diameters from 50 to 200 mm. The series offers basic dynamic load ratings from 5.10 to 25.8 kN and basic static load ratings from 7.18 to 51.2 kN across the listed models.
