V-RING VS 130 117x131x18 Axial Shaft Seal

V-RING VS 130 117x131x18 Axial Shaft Seal

V-RING VS 130 is an axial shaft sealing ring designed for shafts with diameters from 125 to 135 mm. The free ring dimensions are 117x131x18 mm. The V-Ring is installed directly on the shaft and rotates with it, while its flexible sealing lip operates axially against a stationary counterface.

V-RING VS 130 Dimensions

The catalogue dimensions for VS 130 are:

Shaft diameter range: 125-135 mm

Free inside diameter: 117 mm

Outside diameter: 131 mm

Overall height: 18 mm

Profile dimension: 13.1 mm

The complete free ring dimensions are therefore:

117x131x18 mm

The designation VS 130 does not mean that the free inside diameter of the ring is 130 mm.

What Shaft Diameter Is V-RING VS 130 Designed For?

V-RING VS 130 is designed for shaft diameters within the range:

125-135 mm

Its free inside diameter is:

117 mm

The elastomeric body of the V-Ring stretches during installation on the shaft.

This is why a V-Ring with a free inside diameter of 117 mm can be installed on a shaft with a significantly larger diameter.

The specified shaft diameter range should therefore be used when selecting the correct V-Ring size.

How Does a V-RING VS Work?

A V-Ring operates differently from a conventional radial shaft oil seal.

The V-Ring is mounted directly on the rotating shaft.

Its body rotates together with the shaft, while the flexible sealing lip contacts a stationary counterface positioned approximately perpendicular to the shaft axis.

The sealing lip therefore operates in an axial direction rather than radially against the shaft surface.

This arrangement forms a protective sealing barrier around the rotating shaft.

What Is V-RING VS 130 Used For?

V-Rings are primarily used to help protect sealing areas and rotating assemblies against external contamination.

Depending on the machine design, a V-Ring can provide additional protection for:

Bearings

Bearing housings

Shafts

Radial shaft seals

Rotating assemblies

Machine components

Exact suitability depends on the design of the sealing arrangement and the actual operating conditions.

VS Profile V-Ring

VS identifies a specific V-Ring profile.

The profile geometry is an important selection criterion and should be considered together with the shaft diameter.

When selecting a replacement, verify:

V-Ring type

VS profile

VS 130 size

125-135 mm shaft range

Installation geometry

Counterface

Required elastomer material

Actual operating conditions

A V-Ring with another profile should not automatically be considered equivalent solely because it can be fitted to a similar shaft diameter.

V-RING VS 130 vs Conventional Radial Shaft Oil Seal

A V-Ring and a conventional radial shaft oil seal use different sealing principles.

A conventional radial shaft oil seal is generally installed in a housing bore. Its primary sealing lip operates radially against the surface of a rotating shaft.

A V-Ring is mounted directly on the shaft and rotates with it. Its flexible lip operates axially against a stationary counterface.

The two sealing systems should therefore not be considered direct replacements for each other.

Why Is VS 130 Only 117 mm Inside Diameter?

The free inside diameter of VS 130 is smaller than the shaft diameter for which it is designed.

Free inside diameter:

117 mm

Specified shaft range:

125-135 mm

During installation, the elastomeric V-Ring body stretches around the shaft.

This creates the required fit between the V-Ring body and the rotating shaft.

For this reason, V-Ring selection should be based on the specified shaft range and profile rather than simply matching the free inside diameter to the shaft diameter.

How to Select V-RING VS 130

When selecting this V-Ring, verify at least:

Product type: V-Ring

Profile: VS

Size: VS 130

Shaft diameter range: 125-135 mm

Free ring dimensions: 117x131x18 mm

Installation geometry

Counterface geometry

Required material

Operating medium

Temperature

Rotational speed

Actual service conditions

The required elastomer material and application-specific operating limits should be confirmed for the exact product before installation.

FAQ

What are the dimensions of V-RING VS 130?

The free ring dimensions are 117x131x18 mm.

What shaft diameter is VS 130 designed for?

V-RING VS 130 is designed for shafts with diameters from 125 to 135 mm.

Does VS 130 have a 130 mm inside diameter?

No. The free inside diameter is 117 mm. VS 130 is the V-Ring size designation and should not be interpreted as the free inside diameter.

Why can a 117 mm V-Ring fit a 130 mm shaft?

The elastomeric body stretches during installation. VS 130 is specifically dimensioned for installation on shafts within the 125-135 mm range.

Does V-RING VS 130 rotate with the shaft?

Yes. The V-Ring is installed directly on the shaft and rotates with it. Its flexible sealing lip operates axially against a stationary counterface.

Is V-RING VS 130 the same as a 130 mm radial shaft oil seal?

No. A V-Ring is an axial sealing element mounted directly on the shaft. Its operating principle differs from a conventional radial shaft oil seal installed in a housing.

Is V-RING VS 130 made from NBR?

The material cannot be determined from the VS 130 designation alone. VS identifies the profile and 130 identifies the size. The elastomer material must be confirmed for the exact product or manufacturer.

Can another V-Ring profile replace VS 130?

Not automatically. The profile, shaft diameter range, installation geometry, material and operating conditions should all be verified before selecting an alternative.
