FAQ

What type of housing is the RALE30-NPP-B designed for?

It is designed for housings with a spherical seat to accommodate its spherical outer ring. This design allows it to compensate for initial shaft misalignment, making it ideal for pillow block and flanged housing units.

The eccentric locking collar provides a simple, quick, and secure method for mounting the bearing on a shaft. It is particularly effective in applications where the direction of rotation is constant.

The 'NPP' designation indicates that the bearing is equipped with P-type lip seals on both sides, offering effective protection against contamination and grease retention. The '-B' suffix denotes the spherical outer ring design for self-alignment.
