The collar assembly consists of two knurled collars which clamp directly onto a shaft and feature a male-female connecting hub that provides a range of adjustment. Designed for accurate fine-tune positioning, the collars connect using 40 pitch threads that operate smoothly, each traveling 0.025 per turn. Since the entire assembly consists of two one-piece collars which clamp directly to a shaft and screw into each other, it provides superior axial holding power. To make a simple axial adjustment, just clamp one side of the assembly on a shaft, move the other side, then clamp it, and repeat the process infinitely as needed.
