Heavy Duty Shaft Collars

Heavy duty shaft collars are designed for maximum holding power in high-load applications. Featuring larger outer diameters, widths, and clamp screws, they are available in one- and two-piece designs. Made from 1215 lead-free steel with a black oxide finish or 303 stainless steel, they support bore sizes from 3" to 6" (75mm to 150mm).
