Amsted Seals has a decades-long track record of proven performance in the rail industry. Our range of bearing seal options ensure the utmost reliability and durability in the harsh operating environments of rail.
With proven railroad performance since 2010, the Tru-Guard® boasts a true non-contact, virtually zero-torque seal design.
The most common bearing seal used for the last 20 years, the DDL is ideal for customers looking for reliability with less concern about seal torque.
Introduced in 1995, the ST-212 is a lower torque seal option with little-to-no grease purge.
Since 2006, the Efficiency Plus® has helped avoid grease purge with a low-torque labyrinth seal design.
