FAQ

What does the ‘NPP-NR’ suffix mean on the INA RAE40-NPP-NR?

The ‘NPP’ indicates that the bearing is fitted with effective P-seals on both sides for protection against contamination and lubricant loss. The ‘NR’ suffix signifies that the outer ring has a groove and is supplied with a snap ring for axial location.

Can this bearing accommodate shaft misalignment?

Yes, the RAE40-NPP-NR has a spherical outer ring which allows it to compensate for initial static misalignment of the shaft when it is mounted in a suitable housing (e.g., a pillow block or flange unit).

What is the correct procedure for mounting this bearing with its eccentric locking collar?

To mount, slide the bearing onto the shaft. Turn the eccentric locking collar in the direction of shaft rotation until it locks securely. Then, tighten the set screw in the collar to the manufacturer’s recommended torque to finalize the mounting.
