SNH Plummer Block Housings

They are designed to permit flexibility in the bearing choice, lubrication, seal and method of location. A number of housing variations can be created using the horizontally split housing. They have two attachment bolts for adjustments. The SNH type is interchangable with earlier SNA type.

They can be fitted with a variety of seals like a two part double lip seal, felt seal, V ring seal and labyrinth seal. Rubbing type seals can be used for temperatures ranging from -4 0° C to100°C for peripheral speeds. For higher speeds, labyrinth seal may be used.

Double Lip Seal Made of Polyurethane Has a good elastic property Simple to mount Requires grease lubrication Needs fine surface finish V Ring Seal Made of nitrile rubber Has a thin sealing lip Not sensitive to surface finish Simple to mount Grease or oil lubrication Felt Seal Simple and reliable sealing Grease lubrication Can be mounted on smooth or stepped shafts Can be used for higher speeds Fine contact surface

The plummer blocks are made of gray cast iron or graphite cast iron. They can be grease or oil lubricated. The selection is done as per the operating conditions. The method of lubrication varies as per the lubricant.

These housings are designed to carry loads that act at right angle to the surface.
