Introduction to various types of rubber seals

Lip Lip rubber seal ring type a lot, as shown in FIG V-shaped, shaped, L-shaped, Y-shaped, and the like.

V-shaped ring rubber lip seal it is secret A: A typical form of rings, lip seals is the oldest and widely used applications. Reciprocating portion generally used for hydraulic, pneumatic and hydraulic machines, working pressure up to 30MPa, cloth rubber V-ring of up to 60MPa, operating temperature up to

U-ring rubber seals are generally simple to use single structure, friction is small, should be equipped with a support ring. Not only for reciprocating seals but also for low-speed rotary seals commonly used in hydraulic and hydraulic press. Sealable hole (refer to the inner surface of the cylinder park, etc.) or the shaft.

L-shaped rubber seals for large diameter less low pressure hydraulic or pneumatic piston seals. Seal holes.

J-shaped rubber seals for low and medium pressure hydraulic and pneumatic piston rod seal. Also as a low-speed rotary seals and dust seals. Shaft seal.

Large Y-shaped rubber ring simple and compact structure, strong ability of anti-wear roots, more stable working position, only need to use the pressure fluctuation is large support ring, high pressure should be added rings. For hydraulic and pneumatic reciprocating seals. Sealable hole or shaft,

Small YA-shaped rubber seals sectional aspect ratio close to or even greater than 2, without the use of a support ring, stable performance, with the characteristics of the remaining large Y-shaped ring, widely used in hydraulic and pneumatic reciprocating seals. Sealable hole or shaft.

Small YBd seal - rings, inner lip short, long outer lip, a short length of lip protection lip (lip work), you can prevent lip bite, without support ring, the rest of the above characteristics, widely used in hydraulic and pneumatic reciprocating seal. Sealable hole or shaft

YBD small rubber ring with small YBd rings - just turn. Within an outer lip lip long short, characteristics and use the occasion to rest with a small seal-shaped seals YBd same.

Rubber seals are expected through the use of vulcanized rubber compound made, the technical parameters of performance in the hardness of the rubber ring, tensile strength, elongation at break, tear strength, in the electronics industry has a good application of fire-resistant rubber ring, fire-retardant rubber ring, UL94v0 rubber ring. We can also design according to customers drawings of different shapes of the rubber ring, such as a rubber o-rings, y-type rubber seal ring, star-shaped rubber ring.
