The SKF PWTR 2RS is a stud-type cam follower built around a cylindrical roller bearing. It handles radial loads in cam-driven and support positions. The 2RS suffix means there is a contact seal on each side, so grease stays in and dust and moisture stay out. You will find it on machine tools, packaging lines, conveyors and cam mechanisms that need smooth, repeatable rolling.
Reading the code helps you order the right size. PWTR is the SKF series of cam followers and support rollers with a cylindrical outside surface and a threaded stud. The digits after it give the outside diameter in millimeters: PWTR 15.2RS measures 15 mm across, PWTR 20.2RS measures 20 mm. With four-digit codes such as PWTR 1542.2RS, the first pair (15) is the outside diameter and the second pair (42) is the overall width. The 2RS ending tells you both sides carry contact seals, which keep particles out and hold the grease in place.
These rollers show up in food processing, automotive plants, metalworking and packaging operations. Typical mounting points include actuating cams, linear guide systems, conveyor rails, industrial sewing machines and cutting equipment. Because they take radial loads and a degree of axial thrust, they suit mechanisms where the cam turns at moderate speed and you want long intervals between maintenance stops.
When you pick a size, check the outside diameter, the width and the stud thread. Choose the 2RS version for dirty or damp conditions; in a clean, high-speed setup an unsealed variant may be worth reviewing. During installation, line the stud up with the raceway and tighten the nut to the recommended torque. The sealed rollers arrive lubricated for life, so under normal conditions no relubrication is needed.
On equivalents: cam followers from other makers that use the same dimensional designation can be swapped in, provided the outside diameter, width and thread match. Tolerances and load ratings may differ between manufacturers, so compare the full part number and the critical dimensions before you commit.

Frequently asked questions
- What does 2RS mean on a PWTR cam follower?
- It means the roller has a contact seal on each side. The seals hold the grease in and keep dust, water and particles out, which helps in contaminated environments.
- How do I read the code PWTR 1542.2RS?
- In PWTR 1542.2RS, the first two digits (15) give the outside diameter in millimeters and the next two (42) give the total width. The 2RS suffix indicates double sealing, so you can identify the main dimensions from the code.
- Does this roller need extra lubrication?
- No. SKF PWTR 2RS rollers are sealed and lubricated for life. Under normal operating conditions they do not need relubrication. Only in severe applications or at high temperatures might additional lubrication be considered.
