Product Overview
Ruland clamp style shaft collars do not mar the shaft, are infinitely adjustable, and have superior holding power when compared to set screw collars. This one-piece double wide shaft collar has a 25mm bore, 8mm keyway, 45mm OD, and 33mm width. It has about 25% more holding power than standard round bore collars of equivalent bore size and can be used as a short rigid coupling in applications where standard length rigid couplings will not fit. The addition of a keyway allows for use in positive drive applications as a shaft collar or for extra torque capacity when used as a rigid coupling. Tightly controlled face to bore perpendicularity is maintained (TIR of < 0.05mm) which is critical when the collar is used as a load bearing face, mechanical stop, or for component alignment.
