The INA PWKR series support roller is a cylindrical roller bearing with a crowned outer profile, designed to withstand high radial loads in cam and linear guide mechanisms. Its robust construction and double-sided sealing make it suitable for demanding applications with oscillating motion or continuous rotation. MR Accesorios Industriales carries this line as an official brand, 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 a threaded stud and cylindrical rollers. The number that follows indicates the roller's outer diameter in millimeters: for example, PWKR35-2RS-XL corresponds to a roller with a 35 mm outer diameter, PWKR40-2RS-XL to 40 mm, and so on up to PWKR90-2RS-XL. The 2RS suffix indicates double-lip double-sided 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 high-rigidity, low-friction rolling contact, even with reciprocating motion.

To select the right roller, take into account the stud diameter, radial load and type of motion. The 2RS sealing protects against dust and moisture, but requires adequate lubrication and precise alignment to prevent premature wear. Internal clearance and preload must be verified according to the application. During assembly, make sure 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 and the alternatives available for your equipment.
