THK CFH16UUAB Eccentric Cam Follower
CFH16UUAB is a high‑rigidity, eccentric stud‑type cam follower from THK’s CFH‑AB series, featuring double‑sided contact seals (UU), hex sockets on both stud ends, and a built‑in grease nipple. It enables precise radial position adjustment via its eccentric stud design, making it ideal for compact, high‑accuracy cam and linear motion systems.

Key Features
- Eccentric Stud Design: 0.5 mm eccentricity allows fine radial position adjustment by rotating the stud, eliminating the need for precision machining of mounting holes.
- Dual Hex Sockets (AB): Hexagonal sockets on both stud ends enable installation and adjustment from either side in confined spaces.
- Double‑Sided Seals (UU): Prevents grease leakage and contamination ingress, suitable for harsh industrial environments.
- Built‑in Grease Nipple: Integrated lubrication port for easy relubrication, extending service life.
- Cylindrical Outer Ring: Provides stable contact with flat cam surfaces for smooth rolling motion.
- High Load Capacity: Caged needle roller construction delivers excellent radial load capacity in a compact profile.
- Carbon Steel Construction: Ensures high rigidity, wear resistance, and durability.
