Ruland shaft collars offer high holding power and precise face to bore perpendicularity making them ideal for the precise location of motor components, such as bearings. They can also be used for spacing, stopping, guiding, and mounting depending on the design of the motor. Ruland clamp type shaft collars are ideal for motors as they do not the mar the shaft, are infinitely adjustable, and have high holding power. Clamp type shaft collars wrap evenly around the shaft allowing for consistent clamping forces and a more precise fit when compared to set screw collars. Ruland offers one- and two-piece shaft collars in a variety of styles to match the varied needs of motor manufacturers. Two-piece shaft collars are mated throughout the manufacturing process for proper fit, alignment, and to maintain high holding power. Two-piece shaft collars have standard options with a balanced design which is suitable for high speed motors where the collar will be used on a rotating shaft.
Ruland manufactures shaft collars for motors from select North American bar stock in 1215 lead-free steel with a black oxide finish for high holding power, 303 & 316 stainless steel for corrosion resistance, and lightweight 2024 aluminum for low inertia. They are available in bore sizes from 1/8” to 6” and 3mm to 150mm.
