Ultra-Class is NTN’s upgraded mounted-unit line. The flinger behind each contact seal throws water and dust clear before it reaches the seal lip, and the black oxide finish adds corrosion resistance on the insert rings. The eccentric collar locks by cam action in one direction of rotation and needs no shaft machining. The insert seats spherically in the housing, so the unit takes up moderate misalignment at installation.

Compatibility and replacement:

Two-bolt pillow blocks at 5/8 in bore come from AMI (UELP201-10), Peer (UELP201-10), SealMaster (MP/NP), Link-Belt (P3U/PB), Dodge (P2B) and Browning (VF). Bolt centres and centre height differ between makers; this unit has 3-3/4 in bolt centres and 1-5/16 in centre height. NTN UELPL-5/8 is the same insert in a low-centre-height housing, and UCP-5/8 uses a setscrew insert in place of the collar, so both are related builds.
