Shaft Collar, 3/8″ Hex Bore, 303 SS, Outside Dia.: 7/8″



PengXin 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. PengXin 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″.
