The SKF PWKR 2RS cam follower and support roller is a cylindrical roller bearing with an integrated stud, designed to withstand high radial loads and oscillating or rotating movements in cams, guides and transmission systems. Its robust construction and 2RS sealing make it suitable for environments with dust and moderate humidity. It is used in machine tools, packaging equipment, production lines and lifting mechanisms, where precision and durability are critical.

The PWKR designation identifies SKF cam followers with a cylindrical outer profile and a threaded stud. The number that follows indicates the outer diameter in millimeters: for example, PWKR 35.2RS has a 35 mm outer diameter, PWKR 40.2RS has 40 mm, and so on up to PWKR 90.2RS with 90 mm. The .2RS suffix indicates double contact sealing, which protects against the ingress of contaminants and retains the lubricant. This nomenclature allows quick identification of the size and sealing characteristics.

These rollers are used in applications where radial loads must be supported and motion transmitted with precision. In Argentina, they are common in the automotive industry, in packaging machines, in material handling equipment and in cam systems for valve actuation or indexing mechanisms. They are also found in presses, punching machines and textile equipment, where reliability and wear resistance are essential to maintain productivity.

To select the right roller, take into account the required outer diameter, the type of load (radial, axial or combined) and the environmental conditions. The 2RS sealing is recommended in dirty or humid environments; if higher speed is required, check the lubrication and internal clearance. During mounting, ensure correct alignment of the stud and avoid impacts that could damage the seals or raceways. Proper lubrication and preload adjustment directly influence the service life of the bearing.

Regarding equivalences, SKF PWKR cam followers can be interchanged with products from other manufacturers that follow similar designations, such as those of the KR, KRV or NUKR series from different brands. However, it is essential to verify the critical dimensions (outer diameter, width, stud thread) and load capacities before replacing a component. Not all rollers with the same outer diameter have the same performance; always consult the technical specifications.
