The INA KR series cam follower is a roller bearing with an integrated stud and a cylindrical outer surface, designed to act as a cam follower or support roller in motion systems. It mounts directly on the stud and withstands high radial loads under continuous rotation. It is used in cams, linear guides, conveyors and drive mechanisms where precise, durable rolling contact is required.
The KR series designation reads as a size code: KR followed by a number indicating the roller's outside diameter in millimeters. For example, KR16, KR19, KR22, KR26, KR30, KR32, KR35 and KR40 correspond to rollers with outside diameters of 16, 19, 22, 26, 30, 32, 35 and 40 mm. The suffixes shown in the catalog indicate sealing, cage or design variants; when requesting a quote, send the complete part number to identify the exact version.
In Argentine industry, INA KR series cam followers are used in machine tool cams, conveyor guides, lifting systems, presses, packaging equipment and automated production lines. They also appear in the food, cement and automotive industries, where a compact bearing that withstands radial loads and moderate tilting moments is required.
To correctly select a cam follower, take into account the radial load, rotational speed, sealing type (open or sealed), internal clearance and lubrication method. Mounting must ensure precise alignment between the stud and the raceway; excessive misalignment accelerates wear. Proper lubrication and correct sealing extend service life in dusty or humid environments.
INA KR series cam followers are interchangeable with equivalent products from other brands that follow the same dimensional nomenclature. When replacing a roller, verify the outside diameter, stud diameter, width and sealing type. A specialist can identify the right alternative based on dimensions and application.
