Oil seals
Oil seals
Oil seals are rotary seals. They are used to seal rotating or swivelling machine elements (mainly shafts). The areas of application are diverse and can be found in all areas of mechanical and apparatus engineering.
Typical applications
- Engine and gear manufacturing
- Industrial gears
- Gear engines
- Electric motors
- Internal combustion engines
- Pumps
- Drive systems
- Agricultural machines
- Construction machines
- Household appliances
- Washing machines (household and industrial)
- Dishwashers
- Heavy industry machines
- Rolling mills
- Ship building
- Wind power generators
Demands made on shaft seals
- Leakage-free sealing under all operating conditions
- Low friction, low power loss, little heat development
- Simple installation, easy replacement
In most applications, the shaft seal is required to hold back a lubricating medium within the space to be sealed. At the same time, the demand can be to prevent the intrusion of dirt, dust, etc. into the space to be sealed. Shaft seals best fulfi l these tasks and are therefore the most frequently used
sealing elements.
The structure of a shaft seal is characterised by
-
an elastomer part, sealing lip, or protective lip, if applicable outer diameter, and coating of the metal case (reinforcing ring)
-
a metal case
-
a spring
Norms
The design of the shaft seals is based on the German norm DIN 3760. Internationally, ISO 6194 is also applied.
Quality
Our shaft seals are manufactured to strict quality demands in all areas, from the development, the procurement of source materials to the processing and despatch. Modern manufacturing methods, many years of experience, strict testing and continuous documentation of all steps guarantee the fulfi lment of our own quality demands and particularly those of our customers. The quality of the products is under constant control for compliance with common international norms and standards. The following delivery quality applies to all standard shaft seals for which no other arrangement has been made:
Shaft seals according to DIN 3760
Acceptable quality levels AQL 1.5 according to DIN ISO 2859-1
Customer-specifi c quality requirements can be agreed individually under purchase orders.
