Split Plummer Block Housing Seals

Bearing King offer a variety of seals for split plummer block housings

An important advantage of SNL plummer block housings is that they can be fitted with different types of seals. Standard SKF seals include split four-lip seals, V-ring seals, felt seals, labyrinth seals and heavy-duty taconite seals with a radial labyrinth. The seals are easy to install and sre supplied separately. All the standard seals, as well as the seals for use with oil lubrication, are shown below

TSN-L Four-lip seals
With shaft speeds continuously increasing, there was a need for a sealing solution that could accommodate higher speeds with the same high level of performance that the SKF double-lip seal could provide at lower speeds. To meet that need SKF developed a robust, easy to mount four-lip seal that can accommodate peripheral speeds up to 13 m/s. This four-lip seal is made from a specially formulated thermoplastic elastomer. Operating temperature range for the seal is between -40 and +100 degrees C. Each package of four-lip seals contains two seals.

TSN-V V-ring seals
V-ring seals are two-piece seals that consist of a V-ring and a galvanized, sheet steel sealing washer. A rubber lip, vulcanized to the sealing washer, fits into the seal groove in the housing. The V-ring fits tight on the shaft and seals axially against the washer. As it is turning with the shaft, the V-ring acts as a flinger. These seals are typically used in difficult applications e.g. where there are high speeds or rough finished shafts. They can accommodate peripheral speeds in excess of 7 m/s. Each package of V-ring seals contains two seals.
