SEAL TXC
The TXC profile is a double-lip shaft seal consisting of a single metal case with a rubber coating, a primary sealing lip with an integrated spring, and an inward-facing dust lip that protects against external dirt buildup while also allowing pre-lubrication of the seal to prevent dry running during startup. It is also ideal for limited-space applications where a dust-exclusion lip is required.
- Good static sealing.
- Compensation of different thermal expansion.
- Reduced risk of fretting corrosion.
- A higher surface roughness of the bore is allowed.
- Sealing for low- and high-viscosity fluids
- Modern primary sealing lip with low radial forces
- The dust lip enables dry pre-lubrication and serves as a barrier against airborne contaminants.
- Compact design for use in tight spaces

TOLERANCE FOR THE INNER DIAMETER OF THE SEAL
When not under pressure, the inside diameter of the sealing lip is always smaller than the shaft diameter. The difference between the two dimensions is known as interference or pre-fitting. Depending on the shaft size, the sealing lip diameter is estimated to be between 0.8 mm and 3.5 mm smaller. It will depend on the setting chosen by each manufacturer.
