Industrial HR-1-2-XB Cam Follower

SMITH Bearing HR-1/2-XB Cam Follower is a heavy-stud, sealed cam follower with a 1/4-inch threaded stud (1/4-28) and a 1/2-inch roller, delivering a compact footprint suitable for tight spaces in automated equipment and inline machinery where reliable cam action is required. The roller measures 1/2 inch in diameter and 3/8 inch wide, with a flat surface that provides stable contact along flat or crowned cam tracks and helps minimize side load during motion precisely. Internally it uses sealed needle bearings in bearing steel and is not relubricatable, enabling maintenance-free operation in dirty or enclosed environments where grease channels are impractical and exposure to contaminants is a concern. This model is listed in SMITH Bearing’s HR Series catalogs as HR-1/2-XB, reflecting its heavy-stud design and compatibility with standard stud-type cam follower installations used across automated machinery and factory equipment, and it is widely stocked by distributors such as Grainger and Applied.
