IKO CFS2 Miniature Cam Follower
CFS2 is an ultra‑compact miniature stud‑type cam follower from IKO’s CFS series, designed for light‑load, high‑precision cam mechanisms and linear motion systems. It features ultra‑fine needle rollers in a thick‑walled outer ring, a hex socket head, and a shielded structure. This bearing is optimized for outer‑ring rotation, offering low friction, minimal radial clearance, and stable performance in space‑constrained precision equipment.
