heavy duty seals for construction machinery and production plants

Mechanical seals for  construction machinery and production plants

they are also known under other designations, such  as lifetime seals, floating seals, duo cone seals,toric seals and heavy duty seals.The seals consist of two metallic seal rings. They are mounted in separate housing face to face. The elastomeric elements center the seal in the housing. There are  two tapered cones in the housing and at the O.D. of the seal. The taper increases with the depth of the bore due to the  different grade of  the cones. The housing shape can normally be machined on a NC machine tool.

                       Diameter  35mm    ---  Diameter  1425mm 

Types:

There are two different types of Mechanical Face Seals:the most  common form is Type DO,which is characterized by the use of an O-Ring as the secondary sealing element.

Type DF,on the other hand, has an elastomer with a  diamond-shaped  cross section as a secondary sealing element instead of the O-Ring.

Technical data for metal seal rings:

Material	9Cr6Mo	15Cr3Mo	15CrMo
Process	Cast	Cast	Cast
Cost	High	Medium	Low
Wear Life	High	High	Medium
Corrosion Resistance	High	Medium/High	Low
Scoring  Resistance	High	Medium	Medium

Technical Data for O-Ring:

Material: NBR

Hardness: 60-65 Shore A

Temperature range: -20°C to +100°C

Advantages:- Simple,reliable design- High sealing effect against dirt,dust,water and abrasive media from the outside and against oil and grease from the inside- Cost-effective- Long service life- Self-centering to compensate for shaft eccentricity or misalignment- Maintenance-free- Easy to assemble
