THK CFS-A Series Cam Follower

The THK CFS-A Series is an outer-ring compact type cam follower that contains extremely fine needle rollers inside. Its outer ring diameter is kept extremely small relative to the stud diameter, allowing for a much more compact overall design compared to standard cam followers.

This makes the CFS-A Series a good fit for applications where space is limited, but you still need the reliability and load handling of a needle roller cam follower. It’s available in stud diameters from 1.4mm to 6mm, making it especially suited for smaller, precision oriented setups.

The basic load rating with cage ranges from 0.288 kN to 2.06 kN dynamic and 0.201 kN to 2.16 kN static, while the full roller version offers 0.572 kN to 4.61 kN dynamic and 0.482 kN to 6.27 kN static.
