The CRBF Series flanged crossed roller bearings integrate a bolt-on outer ring flange for direct surface mounting without additional housing machining. This ready-to-mount configuration dramatically simplifies design integration while maintaining full crossed roller load capacity. Ideal for direct-mount rotary platforms, assembly line turntables, and compact welding positioners.
