The SKF PWKR 2RS is a cam follower and support roller built around a cylindrical roller bearing with an integral stud. It handles high radial loads and oscillating or rotating motion in cams, guides, and transmission systems. The 2RS sealing makes it a practical choice for dusty or moderately humid environments. Typical installations include machine tools, packaging equipment, production lines, and lifting mechanisms where precision and durability matter.
SKF uses the PWKR prefix for cam followers with a cylindrical outer profile and a threaded stud. The number after the prefix is the outside diameter in millimeters: PWKR 35.2RS has a 35 mm OD, PWKR 40.2RS has 40 mm, and so on. The .2RS suffix means double contact seals, one on each side, which keep contaminants out and grease in. Reading the code this way gives you the size and sealing at a glance.
These rollers suit applications that need radial load support and accurate motion transfer. You’ll see them in automotive production, packaging machinery, material handling equipment, and cam systems for valve actuation or indexing. They also appear in presses, punching machines, and textile equipment, where consistent performance and wear resistance keep lines running.
When selecting a PWKR roller, start with the outside diameter required by your housing or cam. Then check the load type—radial, axial, or combined—and the operating environment. Choose 2RS sealing for dirty or humid areas. During installation, align the stud properly and avoid hammering on the seals or raceways. Correct lubrication and preload adjustment have a direct effect on bearing life.
For replacements, SKF PWKR rollers can often be interchanged with similar cam followers from other manufacturers, such as those in the KR, KRV, or NUKR series. Always confirm critical dimensions—outside diameter, width, and stud thread—and compare load ratings. Two rollers with the same OD are not automatically identical in performance.

Frequently asked questions
- What does the 2RS suffix mean on PWKR rollers?
- The 2RS suffix indicates double contact sealing, one seal on each side of the roller. This protects against dust, water, and other contaminants while retaining lubricating grease, which extends service life in demanding environments.
- How do I choose the correct PWKR roller size?
- The number in the designation is the outside diameter in millimeters. Select the size that matches the housing or cam where it will be mounted. Also consider the radial load and working conditions to ensure optimal performance.
- Are SKF PWKR rollers interchangeable with other brands?
- They can be interchangeable with rollers from other manufacturers that have equivalent dimensions, such as those with KR or KRV designations. However, always verify exact measurements and load capacities before replacing, since performance can differ.
