Typ T

Type T with PTFE sealant blade with fillers is suitable for non-lubricated or poorly lubricated applications. They have high temperature resistance and increased pressure resistance. Due to the flexibility of the PTFE material, the necessary contact force on the sealed shaft is achieved without the use of a tension spring.
It prevents the "stick-slip" effect at slow rotational speeds and is also suitable for higher circumferential shaft speeds.
Higher shaft hardness, min. 50HRC and lower tolerance shaft eccentricities are required for application.
This type has a metal outer sleeve which is used for a firm and accurate seating in the bay. Requires a more precise design of the outer perimeter of the storage compartment.

Dimensions from 10 mm shaft diameter
