TSN509 C SKF split felt seals

Both SNL and SE plummer (pillow) block housings are available with different standard sealing solutions. Felt seals or strips are simple and effective. At circumferential speeds above 4 m/s, a small gap forms between the felt and shaft, transforming the contact seal into a non-contact, gap-type seal. In applications where bearings are mounted on a plain shaft with an adapter sleeve, split felt ring seals are typically used.
