Ruland Manufacturing Company has been manufacturing an extensive line of shaft collars and couplings since 1973. Ruland shaft collars are widely used as mechanical stops and load-bearing faces, as well as to position components on a shaft. They are available in one-piece, two-piece, heavy-duty and quick-clamping configurations. The company manufactures these shaft collars to fit shafts ranging from 1/8 inches (3.2 mm) to 6 inches (152.4 mm).
The Ruland Coupling catalogue includes a wide range of rigid, beam, bellow, control flex, disc, jaw and oldham couplings. Rigid shaft couplings by Ruland are designed to align or connect shafts at low speed and torque, and are available with or without keyways in one- / two-piece and set screw designs. Raptor Supplies is an authorised Ruland coupling distributor offering a wide variety of these shaft collars and couplings, along with various coupling accessories.
