Harsh operating environments and lubrication issues often lead to early seal failure, allowing contaminants to get into a bearing and lubrication to seep out. Timken's spherical roller bearing solid-block (SRB) housed units have many primary and secondary sealing mechanisms to choose from.
Labyrinth Seals - DuPont™ Teflon®
- High-speed applications.
- Superior in dirty and wet conditions.
- Able to operate at high temperatures.
- Impervious to most chemicals.
Triple Lip Seals – Urethane
- All the benefits of Nitrile, plus it's resistant to abrasion.
Secondary sealing options offer an additional barrier that protects the primary seal. These economical secondary seals and Timken's auxiliary steel covers are easily outfitted on all Timken spherical roller bearing solid-block housed units.
