Industrial YR-1-1 8-X Flat Yoke Roller

Smith YR-1-1/8-X Flat Yoke Roller is a sealed yoke-type cam follower engineered for compact, high-load motion in conveyors, automation lines, and other industrial equipment. It features a 1.1250 in roller diameter, a 0.3125 in bore, and a 0.6250 in roller width, with an overall width of 0.6875 in, enabling installation in tight spaces. The unit is manufactured from bearing steel and is sealed to resist dust and contamination, reducing maintenance. It carries a static radial load rating of 6,200 lbf and a dynamic radial load rating of 3,030 lbf, making it suitable for moderate to heavy radial loads in cam follower configurations. Shaft-fit recommendations include a press-fit maximum diameter around 0.3130 in and a slip-fit minimum around 0.3118–0.3122 in, with nominal shaft diameters tuned for either slip or press fit. This flat-yoke variant is part of the YR family and is designed to be interchangeable with Smith YR 1-1/8-X style cam followers, providing a low-profile mounting head and reliable performance in constrained spaces. Common applications include guiding and supporting moving elements in automated conveyors, packaging machinery, and other equipment that relies on robust, sealed yoke cam followers.
