The UTSL seal type is very similar to the UTS type, but on the dynamic side it has a multifunctional double lip which:

• mitigates any stick-slip effect thanks to a fluid ring between the secondary lip and the main one
• blocks any external impurities
• counters the shrinking of the material at low temperatures;
• works as a stabilizer

• Good sealing effect at high and low pressures
• Good abrasion resistance, wear-resistant
• Unaffected by sudden loads
• Suitable for small grooves
• Simple installation.

APPLICATION

Construction machinery, fork-lift trucks, injection moulding
machines, agricultural machinery, loading platforms and standard
cylinders.
