Description

The BECA 880 profile is a machined, U-ring type filled or virgin PTFE shaft seal, pre-stressed by a stainless steel insert. It is generally used for helical applications.
Derived from the BECA 880 profile, the BECA 889 profile is made specially for food industry applications. It is characterised by a silicone overmoulding on the inside of the seal, which completely hides the V-shaped spring, thus preventing impurities from accumulating in this hard-to-clean area.

Advantages

It is suitable for static, rotating and oscillatory systems
Protects against the effects of mechanical twisting
Low friction coefficient
Excellent abrasion resistance
Suitable for a wide temperature range
Special profiles for the medical, food industry and pharmaceutical sectors
