Hex and D-Bore
Ruland manufactures standard shaft collars with hex and d-bore profiles for proper mating with the appropriate shaft. Hex bore collars allow for added holding power and higher torque capabilities if being used in positive drive applications. D-bore collars are designed for use with d-shafting. They are a better option than set screw shaft collars as they do not mar the shaft, have higher holding power, and are indefinitely adjustable. Ruland manufactures hex and d-bore shaft collars in 1215 lead-free steel with a proprietary black oxide finish and 303 stainless steel. Hex collars are also available in high-strength 2024 aluminum for lightweight applications. D-bore shaft collars available in bore sizes from 1/4" to 1" and hex bore collars from 3/8" to 1/2".
