Description
SKF PWKRE 40.2RS belongs to cam follower and support roller, part of our Bearings range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for PWKRE 40.2RS and any equivalents.
The PWKRE line from SKF covers cam followers and support rollers built as cylindrical roller bearings with a stud machined into the inner ring. They handle radial loads well and tolerate oscillating or rotating motion, which makes them a fit for cam drives, linear guidance, conveyors and lifting equipment. Sealing is integrated, so dusty, damp or permanently lubricated conditions are within their normal working range. MR Industrial Accessories supplies this line for US industrial applications.
Reading the code first saves time. PWKRE is the series designation for a stud-type cam follower with sealing; the figure that follows gives the roller's outside diameter in millimeters, as seen in PWKRE 40.2RS and PWKRE 62.2RS. The .2RS suffix marks double contact seals, one per side, which hold grease in and keep contaminants out. Stud design and sealing variant can change the suffix, so confirm the full code when you inquire.
Typical mounting points include machine tool cams, belt guidance on conveyors, packaging machinery, robotics and lifting mechanisms. Conditions often involve dust, vibration and loads that vary through the cycle. Because the stud is part of the bearing, installation is simpler than a separate shaft and bearing arrangement, and the assembly gains stiffness where a ball bearing would not carry the same radial load.
Selection comes down to four dimensions: outside diameter, overall width, stud diameter and mounting thread. The .2RS seal suits contaminated surroundings; where speeds run high or temperatures are extreme, look at other sealing options. Align the stud with the raceway carefully at assembly, since misalignment cuts service life. Match the lubricant to load and speed, and check internal clearance before start-up.
Crossing to another brand is possible but never automatic. Compare dimensions, load rating, seal type and thread rather than trusting a similar code, because tolerances and designations differ between catalogs. Send the complete code by WhatsApp or email and the team will confirm the match, suggest equivalents and help with selection.
For quotes, include the full designation along with your application details. The team can also advise on mounting, lubrication and maintenance intervals so the roller performs as intended.

Frequently asked questions
- What does .2RS indicate on a PWKRE roller?
- It means the roller carries double contact seals, one on each side. Grease stays in and dust or moisture stays out, which helps in dirty environments. Check that the seal suits your speed and temperature range.
- Which data do I need to pick the right PWKRE size?
- Outside diameter, width, stud diameter and mounting thread are the starting points. Add radial and axial load, speed and ambient conditions. If anything is unclear, send your equipment data and the team will help.
- Can another brand replace an SKF PWKRE roller?
- Equivalent parts exist, but they are not drop-in by default. Dimensions, load capacity, sealing and thread must line up. Do not go by the code alone; verify the specifications, and the team can point you to the right alternative.
