Decoding the designation

TSN is SKF’s housing seal family for split plummer blocks. 516 is the housing size, matching the SNL 516 and SE 516 blocks. C is the felt strip seal execution. Written as TSN-516-C, TSN516C and TSN 516 C.

What these specs mean in practice

A felt seal runs with a small gap that opens up between the felt and the shaft as the shaft turns, so above low speed it behaves as a non-contact gap seal. That keeps friction and heat down and lets it work at higher shaft speeds than a rubbing lip seal, and it leaves the shaft free to move axially inside the housing — which is what a non-locating bearing position needs. The felt also holds a charge of oil and acts as a wiper against dust and coarse airborne dirt.
