SKF KR19 PPA Slotted Head Crowned Cam Follower

SKF KR 19 PPA Slotted Head Crowned Cam Follower is a stud-type cam roller with a crowned outer race and a slotted head, designed to handle high radial loads in cam drives. This sealed stainless-steel unit features a 19 mm roller diameter, 11 mm roller width, and an 8 mm stud diameter (M8) with a 20 mm stud length, enabling compact mounting in tight machinery. It has an overall length of 32 mm and a 4 mm hex socket, supporting up to 5600 rpm and delivering a radial dynamic load capacity of 3.47 kN and a radial static load capacity of 3.8 kN. The assembly is rated for temperatures up to 280 °F and weighs about 0.09 lb. Typical applications include cam drives and other track-based systems such as conveyors and automation equipment, where the crown geometry helps distribute contact stresses and the slotted head facilitates secure mounting under misalignment or load variation. This KR-series cam follower combines robust stud-type attachment with a crowned running surface to accommodate demanding cycling conditions while maintaining sealed performance. It aligns with SKF cam follower specifications that emphasize a crowned outer ring and solid stud mounting for quick installation in automated systems.
