Materials Used in DB Oil Seals

1. Rubber Compounds

ACM (Acrylic Rubber): 70 - 75 Shore A
EPDM (Ethylene Propylene Diene Monomer): 70 - 75 Shore A
FKM (Fluoroelastomer): 70 - 75 Shore A
HNBR (Hydrogenated Nitrile Butadiene Rubber): 70 - 75 Shore A
NBR (Nitrile Butadiene Rubber): 70 - 75 Shore A

These rubber materials are selected for their excellent resistance to oils, heat, and environmental factors, ensuring durability and longevity in various operating conditions.

2. Metal Cage

Steel: AISI 1010
Stainless Steel: AISI 304 and AISI 316

The metal cage provides structural integrity and support to the oil seal, enhancing its performance under pressure and preventing deformation.

3. Spring

Steel: AISI 1070 - 1090
Stainless Steel: AISI 316

The spring element ensures a tight seal by maintaining pressure against the sealing surface, which is crucial for preventing leaks.
