Type
Description
Ordinary type
A single lip seal with a metallic skeleton and a coil spring, the line speed is less than 4m / s.
High-speed type
The same general type, but in the material and structural design for high-speed conditions, the line speed of up to 12 ~ 15m / s, andcan be made of the lips type.
Lips-type
Dustproof and waterproof Vice lip, but has the same general type, can be made of a high-speed type.
Duplex
Can be regarded as a composite structure of the two seals for sealing two different media occasions.
Pressure type
Improve the bearing capacity of the oil seal structure for higher pressure applications.
Sealing oil seal
The lip is located in the outer ring, for sealing the rotation hole lips type, can be made.
End face of the oil seal
The lip is located in the axial end surface, primarily as a dust seal.
Coated iron type
Skeleton exposed metal shell, simple assembly, positioning accuracy, concentricity.
No spring type
Just a skeleton without springs, often used as a dust seal. Compact dimensions, Seal, the height is 4 to 7 mm.
J-shaped
Just a spring without skeleton, commonly used in low-speed mechanical shaft diameter fixed outer ring required when filling platen.For the small shaft diameter can also be made from the skeleton.
U-shaped
End surface like a U-shaped, and only the spring without the skeleton, and packed in a trapezoidal groove.
S-shaped
No skeleton spring, compact size, packed in sealed with felt seal ring trapezoidal slot as dust seal.
Reciprocating type
For low-pressure reciprocating plunger rod seal, pressure up to 0.7MPa, speeds of up to 1 m / s.
Unidirectional power type
The lip tone on the side surface of the light pattern, thread or oblique ribs forward to generate power reflux role. Oil will drip back into the oil side, the reverse oil spill.
Bi-directional power type
Symmetrical pattern of light, such as triangular bump on the side surface of the lip tone, power reflux principle is the same as theone-way power type, positive have power reflux role.
