Clamp Collars

Boston Gear's clamp collars are available in several configurations to meet a variety of design requirements. The setscrew collar is an economical choice when simple positioning on a shaft is desired. However, it is not recommended for high axial loads or when repositioning could be required. The threaded clamp collar provides a higher axial holding force and can be relocated easily but requires a threaded shaft. The 1-piece clamp collar provides a more uniform holding force on the shaft and can be repositioned easily. The 2-piece clamp collar provides a higher and more uniform holding force, and can accept a greater variance in the shaft diameters and be assembled to the shaft without the need to slide it on.
