INA Bearing Inserts 40mm ID 80mm OD GRAE40-XL-NPP-B

The locking collar is preferably tightened in the direction of rotation and secured with a grub screw. This location method prevents damage to the shaft and can be easily loosened again.

The P seal is two zinc-coated sheet steel washers with intermediate NBR part, seal lip axially preloaded.

The R seal is two zinc-coated sheet steel washers extended outwards and angled downwards with intermediate NBR part and radially preloaded seal lip. Better protection against mechanical damage.
Substantial grease reservoir due to the space between the extended and angled sheet steel washers. Used in radial insert ball bearings with inner ring extended on both sides.

To protect the seal lip from mechanical damage, the outer sheet steel washer extends a considerable distance down towards the bearing inner ring.

In addition to bearings with a spherical outer ring (GRAE..-NPP-B and GE..-KRR-B), there are also cylindrical (RAE..-NPP and RALE..-NPP)
