Ruland MCL-15-SS Clamp Style Shaft Collar Stainless Steel

Ruland MCL-15-SS is a 15 mm bore, 34 mm OD, 13 mm wide one-piece clamp-style shaft collar forged from 303 stainless steel, engineered to grip shafts without marring them while providing secure, indefinite adjustability. With a single M5 x 16 socket-head cap screw and bright 18-8 stainless hardware, the collar anchors to a shaft with a seating torque of 5.4 Nm (4.0 mm wrench) and delivers tight perpendicularity between its face and bore (TIR ≤ 0.05 mm), making it well-suited as a mechanical stop, spacing element, or mounting face for gears, pulleys, or bearings. Manufactured in Marlborough, Massachusetts, Ruland specifies 303 stainless steel as the base material, RoHS3 and REACH compliance, a weight of about 0.157 lb, and an operating temperature range from -40°F to 350°F (-40°C to 176°C), ensuring compatibility with demanding environments.
