The INA NUKRE series is a cylindrical roller cam follower built with a crowned outer profile. It handles high radial loads while running against a cam surface or a linear guide, and it is mounted on a shaft or stud with axial fixing. That combination suits mechanisms where the rolling path is the cam itself rather than a separate raceway.
Reading the code helps when you compare options. NU points to a cylindrical roller cam follower, K to a steel cage, R to the crowned running surface and E to the reinforced series. The digits after the letters give the outer diameter in millimeters, so NUKRE35 and NUKRE90 measure 35 mm and 90 mm respectively. Sizes such as NUKRE40, NUKRE47, NUKRE52, NUKRE62, NUKRE72 and NUKRE80 sit between them.
Typical duty includes actuating cams, rolling guides, conveyors, machine tools, packaging lines and lifting equipment. Presses, cranes and reciprocating mechanisms also rely on this style of roller. Because the outer ring can absorb high radial load and tolerate a small amount of misalignment, the roller still works when the raceway is not perfectly parallel to the shaft.
Selection comes down to outer diameter, width and how the roller is fixed axially. The crowned R profile is what compensates for minor misalignment. Lubrication and sealing should match the working environment, and dusty or damp conditions call for protection. The stud or shaft also needs enough rigidity, since bending shortens service life.
Interchange with other brands is possible when the dimensional nomenclature lines up. Check the critical dimensions and the load conditions before committing, and treat the code engraved on the old roller as the most dependable reference when replacing it. If the designation is unclear, send the part number and our team can suggest equivalents and help with the choice.
Quotes are handled by part number through WhatsApp or email, and the team replies promptly. Customers in the United States and several Latin American countries use this route for cam followers and other power transmission components.

Frequently asked questions
- What does the NUKRE code tell me about an INA cam follower?
- The letters break down into cylindrical roller cam follower, steel cage, crowned outer surface and reinforced series. The trailing number is the outer diameter in millimeters, as in NUKRE35 or NUKRE90.
- How do I pick the right cam follower?
- Start with outer diameter, width, radial load and the mounting arrangement. The crowned surface covers slight misalignment. If you still have the original roller, its engraved code is the best starting point.
- Can NUKRE rollers replace other brands?
- Often yes, provided the main dimensions and load capacity correspond. Nomenclature differs between manufacturers, so confirm the code and dimensions before replacing. Send us the part number on WhatsApp and we can help you compare.
