BECA 486

Hydraulic seals / Wiper seals - Scraper seals

BECA 486

Description

The BECA 486 profile is a double acting composite wiper seal composed of a filled PTFE friction ring and two pre-tightened rubber O'Rings.

Advantages

Low friction coefficient; no stick-slip effect
Wide temperature range and excellent chemical resistance, depending on the materials selected
Excellent abrasion and wear resistance
Very good wiping effect against external pollutions
Suitable for large dimensions
