Ealing Products (Rubber

Description : Oil Seals used in  mechanical seal for rotating and static force resist deformation under pressure, thermal, wear and lubricity. The Component with shaft,housing, bore press fit from metal contact.

Material : NBR, VITON and HNBR.

Feature : Rubber Coated with metal case or spring, high mechanical strength, sealant and rusty resistance.

Application : Hydraulic seals, vacuum seals, seals ,engine -motor shaft, transmission seals.Static Seals :
When there is very little or no motion of the mating assembly parts upon the seal, a static condition exists. Usually just an initial compression or periodic (open and close) compression, this type of seal; i.e. a liquid seal in a hose joint, a door seal on a
home.

Dynamic Seals :
Where repeated motions act upon the seal as in a circumferential, axial or angular direction, a dynamic condition exists. Repeated actions upon the seal, either regularly or periodic,this type of seal; i.e. a piston ring seal or shock absorption mechanism.Design Considerations are more complex than static seals, primarily resulting from the changing stress levels. In addition to the static seal considerations, the environment may require.

• • Abrasion resistance becomes important and is affected by the mating surface finishes.
• • Recovery speed after compression to the original released height.
• • Compression set, or the percentage of relaxation of the dimensions versus the original uncompressed dimensions
• • Temperature changes, thermal cycling.
• • Distortion: squeeze, stretch – ability to recover.
• • Physical strength: tensile strength, tear resistan
