Concertina Bellows

Concertina Bellows

Concertina bellows offer protection for many applications, and are designed to prevent the ingress of abrasive dust, dirt and other contaminants in precision machine parts. This can help reduce wear and loss of vital machine accuracy. PAR Group can manufacture concertina bellows in a wide range of fabrics stitched and/or welded to suit your requirements.

Temperature: -150°C to +280°C (depending on material type).

Applications: Protection of shafts and machine slideways from swarf, rust, dirt, product and weld splatter.


Size: Made to order, please enquire. We have instructions on how to measure a bellow to aid the process.
