Tolerance for the inside diameter of the seal (Ød)

Free and without constraint, the inside diameter of the sealing lip is always smaller than the

diameter of the shaft. The pre-tightening or interference denotes the difference between

these two values. Depending on the shaft diameter, the diameter of the sealing lip is generally

considered to be less, between 0.8 and 3.5 mm.

|

DESCRIPTION

The VC5 profile is a shaft seal composed

of a staggered metal cage with a

rubber coating, an external stop and a

primary sealing lip without a spring.

|

ADVANTAGES

Very good static sealing

Very good thermal expansion

compensation

Precise positioning when stopped

Greater roughness is

allowed in the housing

Reduced risk of corrosion

Sealing for high viscosity fluids

Primary sealing lip generating

low levels of friction and heat

|

APPLICATIONS

All types of rotative applications

Machine tools

Agriculture

Construction

Transmissions

Gear boxes

Motors

Pumps
