Description
INA PWKRE72-2RS-XL belongs to 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 PWKRE72-2RS-XL and any equivalents.
The INA PWKRE RS-XL is a support roller with a thick-walled outer ring and cylindrical rollers, built to carry high radial loads and run directly on a raceway. It works as a cam follower or support roller in guiding systems, cams and lifting mechanisms. The RS sealing and the XL execution suit dusty conditions and permanent lubrication.
Read the code in blocks: PWKRE marks the support roller series with a thick-walled outer ring and an inner shaft. The number that follows, as in PWKRE35-2RS-XL or PWKRE90-2RS-XL, gives the shaft diameter or the nominal roller size. The 2RS suffix means double contact sealing, and XL identifies the higher load capacity execution. With those blocks you can pinpoint the exact part in the series.
You will find these rollers on drive cams, linear guides, conveyors, machine tools, presses and lifting equipment. The thick outer ring lets them roll straight on a cam track or guide, taking the high radial loads and shocks that come with reciprocating motion.
For selection, check shaft diameter, outer ring width and sealing type. The 2RS version keeps out dust and moisture, but it needs proper lubrication and careful alignment so the lips are not damaged. Press the roller onto the shaft with an interference fit and avoid impacts on the outer ring. Lubrication may be permanent or relubricable depending on the application, and the raceway should be ground and hardened.
INA support rollers can be interchanged with those from other European brands that share the same dimensional nomenclature, such as SKF or FAG, provided dimensions and sealing type match. There is no automatic equivalence between series: verify diameter, width, load and fastening. If the part number does not match, compare drawings or samples. MR can help you find the equivalent.

Frequently asked questions
- What does the 2RS suffix mean on PWKRE rollers?
- It indicates double contact sealing, one on each side. This keeps lubrication in and blocks dust and moisture, which is useful in dirty environments or with frequent washdowns.
- How do I choose the right INA support roller for my machine?
- You need the shaft diameter, roller width and fastening type. Radial load, speed and environmental conditions also matter. With these data, the correct PWKRE RS-XL part number can be determined.
- Do INA PWKRE rollers have equivalents from other brands?
- Dimensional equivalents exist from other European brands, but there is no universal table. Compare diameter, width, load and sealing. Send the original part number and we will help you look for the alternative.
