INA Radial Insert Ball Bearing 60mm GRAE 60 NPPB

Description

The INA GRAE 60 NPPB is a high-performance radial insert ball bearing, designed for reliability and ease of installation. It features a 60 mm bore diameter and is equipped with effective P-seals on both sides to protect against contamination and retain lubricant. The spherical outer surface allows it to accommodate initial static misalignment when mounted in an appropriate housing. This bearing is fixed to the shaft using an eccentric locking collar, providing a simple and secure mounting solution.

FAQ

Question?
What is the purpose of the eccentric locking collar for the GRAE 60 NPPB?

Answer

The eccentric locking collar is used to secure the bearing's inner ring to the shaft. By rotating the collar in the direction of shaft rotation and tightening the set screw, it creates a tight, friction-based lock that prevents the inner ring from slipping on the shaft during operation.

Question?
What does the 'NPPB' suffix signify in this INA bearing model?

Answer

The 'NPPB' suffix indicates specific features of the bearing. 'NPP' refers to the type of seal, which is an elastomer lip seal (P-seal) on both sides for excellent protection. The final 'B' indicates that the inner ring is prepared for mounting with an eccentric locking collar.

Question?
Can this bearing compensate for shaft misalignment?

Answer

Yes, the GRAE 60 NPPB has a spherical (convex) outer ring. When installed in a housing with a corresponding spherical (concave) bore, it can accommodate initial static misalignment of the shaft, which helps prevent excessive stress on the bearing.
