RUBBER BELLOW SEALS

HC1 / HC12

  • Rubber Bellows Drive
  • To DIN EN 12756 Standards
  • High Speed
  • Bi-Directional

HC_ series are based on the industry

standard "Type 2100" design. HC12 is

standardised to DIN EN 12756 "L1k"

operating length while HC1 is standardised to DIN EN 12756 "L1s".

 

The HC_ design utilises inter-meshing

metal tags which protect the bellows

from torsional strain under higher operating speeds.

 

An optional "BS" o-ring mounted seat is available.
