Cam Yoke Roller Bearing

Cam Followers and Yoke Rollers

Track, guide, and indexing motion

Guided motion needs a roller that carries concentrated load through a heavy outer ring while running on a rail, plate, or cam surface. Listings include a sealed yoke type follower with a 4 in roller diameter and 2.25 in roller width, a Smith MUTD-40 at 40x80x30 mm, and an INA PWTR-1747-2RS support roller at 17x47x20 mm. Decide first between stud type, which threads into a fixture, and yoke type, which pins between two plates, then match roller diameter, width, and whether the outer surface is crowned or cylindrical. Crowned rollers suit flat plate travel; cylindrical ones suit matched tracks. Thinner rolling elements without the heavy ring are needle roller bearings.
