FAQ

What is the advantage of the crowned outer ring on the NURT25R model?

The ‘R’ in NURT25R signifies a crowned (spherically ground) outer ring surface. This design helps to mitigate edge loading when the roller is misaligned relative to the track surface, distributing the load more evenly and significantly extending the bearing’s service life.

What type of lubrication is recommended for the IKO NURT25R?

The NURT25R is pre-packed with a high-quality lithium-based grease. It features a lubrication hole for re-lubrication, which is crucial for applications with high speeds or heavy loads to ensure optimal performance and longevity.

Can this yoke roller handle axial loads?

The NURT series, including the NURT25R, is primarily designed to handle high radial loads. The double row of cylindrical rollers and the thrust washer structure provide some capability to accommodate axial loads that may occur due to mounting errors or misalignment, but they are not intended for primary axial load applications.
