The INA PWKR series support roller is a cylindrical roller bearing with a crowned outer profile, designed to withstand high radial loads in cam mechanisms and linear guides. Its robust construction and double-lip sealing make it suitable for demanding applications with oscillating motion or continuous rotation. MR Accesorios Industriales sells this line, with technical advice to select the right variant according to the stud diameter and load type.
The PWKR series designation is interpreted as follows: the letters PWKR identify a support roller from the INA family, with threaded stud and cylindrical rollers. The number that follows indicates the roller outer diameter in millimeters: for example, PWKR35-2RS-XL corresponds to a roller with 35 mm outer diameter, PWKR40-2RS-XL to 40 mm, and so on up to PWKR90-2RS-XL. The 2RS suffix indicates double-lip bilateral sealing, and XL designates the long-life execution with higher load capacity. Knowing these codes allows you to quickly identify the part.
These rollers are used in machine tool cams, linear guide systems, presses, packaging equipment and conveyor lines. In Argentine industry they appear in dies, stamping machines, sheet feeding devices and lifting mechanisms. Their ability to absorb radial loads and shock forces makes them common in applications requiring a high-rigidity, low-friction rolling contact, even with reciprocating motion.
To select the correct roller, take into account the stud diameter, radial load and type of motion. The 2RS seal protects against dust and moisture, but requires adequate lubrication and precise alignment to avoid premature wear. Internal clearance and preload must be verified according to the application. During assembly, ensure the rolling surface is clean and free of burrs, and apply the recommended tightening torque for the threaded stud.
INA PWKR series support rollers can be interchanged with equivalent products from other brands that follow the same dimensional designation. However, tolerances and load capacity may vary between manufacturers. Therefore, when replacing a roller, always compare the critical dimensions and service conditions. MR Accesorios Industriales can advise you on compatibility for your equipment.

Frequently Asked Questions
- What does the 2RS suffix mean on PWKR rollers?
- The 2RS suffix indicates that the roller has double-lip bilateral sealing, which protects against the entry of dust, water and particles. This extends service life in contaminated environments and reduces the need for frequent maintenance.
- How do I choose the correct diameter for my application?
- The roller outer diameter should be selected according to the radial load and available space. The number in the designation (for example, 35 in PWKR35) corresponds to the outer diameter in millimeters. Contact us with your mechanism measurements and we'll advise you.
- Are PWKR rollers interchangeable with other brands?
- They can be interchanged with support rollers from other brands that share the same dimensional designation, but always verify tolerances and load capacity, as they may vary. MR can help you compare options.
