For cam drives and linear guide systems, the INA PWKR series support roller offers a cylindrical rolling element with a crowned outside surface, built to handle heavy radial forces. Its double-lip sealing arrangement suits both oscillating and continuously rotating duties. MR Industrial Accessories supplies this line and can help you match the right variant to your stud size and load case.

Reading the PWKR code: the letters stand for a support roller in the INA range, featuring a threaded stud and cylindrical rollers. The digits give the outside diameter of the roller in millimeters. So PWKR35-2RS-XL has a 35 mm outside diameter, PWKR40-2RS-XL measures 40 mm, and the series continues through PWKR90-2RS-XL. The 2RS marking means double-lip seals on both sides, while XL points to a long-life version with greater load capacity. With these details, you can pinpoint the part quickly.

Typical installations include cam mechanisms on machine tools, linear guideways, presses, packaging machinery and conveyor systems. The roller's capacity to take radial loads and shock forces makes it a common choice where a stiff, low-friction rolling contact is needed, even under reciprocating motion.

When choosing a roller, consider the stud diameter, the radial load and the motion pattern. The 2RS seal keeps out dust and moisture, but it still needs proper lubrication and accurate alignment to prevent early wear. Check internal clearance and preload for your specific setup. At assembly, make sure the rolling surface is clean and free of burrs, and tighten the threaded stud to the recommended torque.

INA PWKR series support rollers can be replaced by equivalent products from other makers that use the same dimensional designation. Tolerances and load ratings may differ between manufacturers, so always compare critical dimensions and operating conditions before substituting. MR Industrial Accessories can review compatibility for your equipment.
