QUALITY & EXPERTISE FOR YOUR SEALING NEEDS



DESCRIPTION

The BECA 131 profile is a gamma

seal. The design of the metal part

offers additional protection in the

form of a labyrinth in the housing,

should there be a higher pollution level

compared to the BECA 130 profile.



ADVANTAGES

Good dynamic sealing

Very good protection against

external solid particles

Modern axial sealing lip

with a low radial load

Low power loss

Installation in a reduced size

No additional retention system necessary
