Shaft Collars for Machine Tool Applications
Ruland offers an industry-leading selection of one- and two-piece clamp style shaft collars often used in machine tool applications. Ruland shaft collars have precisely controlled face to bore perpendicularity (TIR ≤ .002" / .05mm) which is critical for proper alignment when collars are used as load-bearing faces or mechanical stops. When used as mechanical stops shaft collars offer a safeguard from unintended movement that can ruin expensive components during operation. Ruland offers shaft collars in standard round, keyed, and threaded bore geometries. Round bore is most common and preferred due to the ease of installation. Keyed are used when the collar is being seated against a component on a keyed shaft or for positive drive applications where the collar is mounted to another component. Threaded offers the highest axial holding power as the female threads of the collar mate directly to the male threads of the shaft.
Ruland shaft collars fit shafts from 1/8” to 6” and 3mm to 150mm. They are made from select North American bar stock in 303 & 316 stainless steel for corrosion resistance, 1215-lead free steel for high holding power, high-strength 2024 aluminum for low inertia, and engineered plastic for light duty applications requiring corrosion resistance. Ruland manufactures shaft collars in our Marlborough, MA factory under strict controls using proprietary processes to ensure superior fit, finish, and holding power.
