RUBBER BELLOW SEALS

H502

  • Rubber Bellows Drive
  • To DIN EN 12756 Standards
  • High Pressure
  • Non-Clogging, Self-Aligning
  • Bi-Directional

H502 is a DIN EN 12756 compliant

mechanical seal for metric shafts,

based on the industry standard "Type

502" design. It is widely specified as

a "high-pressure" alternative for existing seal configurations without impacting fitted working lengths.

 

The rubber bellows extends the full

length of the seal, protecting the shaft against wear. The bellows and spring are encased by a metal housing protecting these components from impact damage.

 

An optional "BP" seat includes an extended tail with a slot to accommodate an anti-rotation pin
