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
casting machining
grinding commodity inspection
packing workshop
Advantages:
Mechanical Face Seals are predominantly used for sealing the bearings in construction machinery or production plants operating under extreme arduous conditions and subject to severe wear.These include:- Tracked vehicles,such as excavators and bulldozers- Conveyor systems- Heavy trucks- Axles- Tunnel boring machines- Agriculture machines- Mining machines
