TVN Housings

TVN housings are one-piece plummer block housings with screwed covers. Developed as axle boxes for light rail-bound trucks, they are also used as conventional plummer blocks. TVN housings are made of gray cast iron.

TVN housings are designed to accommodate self-aligning bearings with cylindrical bore. The bearings are mounted directly on stepped shafts. Bearing seating is designed so that the outer ring is free to move axially in both directions.

To locate the bearing a spacing washer or a locating ring is inserted at one side of the bearing. For larger housings appropriate spacers are required.

The housings are used for applications where "cross location" is employed and no washers or locating rings are required. TVN housings have two felt seals placed adjacent to each other at each side. For high temperature applications the felt seals may be replaced by high temperature sealing strips.

Load carrying ability
TVN housings are used for loads acting vertically towards the base plate. The load carrying ability of the housing is limited by the incorporated bearing. If their are loads acting in other directions the magnitude of the load should be within the permissible limits for the housing and the attachment bolts.

Lubrication
TVN housings require grease lubrication. The grease should be selected with reference to the operating conditions.
