Product Description

V-rings - Axial seals for shafts and bearings.

The function of a V-seal is to exclude dirt, water or other aggressive media from entering bearing housings while also retaining grease. The V-seal stretches over the shaft and assumes a tight interference fit. The V-seal rotates with the shaft causing the lip to rotate against the housing or bearing. As the speed increases, friction decreases due to centripetal force. Morgan V-seals Includes VA style, VAX style, VL style, VE style, VS style. Our this kind of products are purchased by Primetal Technology USA LLC which is the subsidiary company of Siemens.

The VS profile is a rubber facial effect V-Ring composed of a conical rear face with a large body with a low radial section. Type S V-rings with bevel back serves as a pressure-less, axial rod seal which is clamped on a shaft. The flexible sealing lip seals a counter face at a right angle to the shaft, preventing dirt, dust and splash to enter the construction. Available in sizes from .180″ (4.5mm) shaft to 8.270″ (210mm). Commonly used in agricultural and automotive applications.
Excellent chemical compatibility and wide temperature range, depending on the type of material chosen
Low friction
Good elasticity
Firm grip on the shaft

Loss of power

The sealing lip of a V'Ring exerts such a low pressure on the contact surface area that the loss of power resulting from it is also low. The variations in power loss depend on the circumferential speed as well as the diameter of the axis in rotation, as shown in the graph below. At speeds greater than 11.0 m/s, the sealing lip has a tendency to detach itself, as the centrifugal force is greater.

Shaft design

Considering that the V'Ring is fitted and tightened by expansion on the shaft, it is driven into rotation with the shaft. The requirements of tolerances and surface conditions (Ra ≤ 3.2 µm) are relatively moderate. We recommend carefully selecting the size using the dimensional chart for applications in which power loss and V'Ring lifespan are important criteria. If the diameter of the shaft Ød1 overlaps two potential V'Ring choices, we recommend selecting the larger V'Ring. The tightness on the shaft will in fact reduce, like the contact pressure of the lip on the back.

2.00 µm - 2.50 µm< 1.0 m/sGrease, dirt
The surface roughness must not have a Ra < 0.05 µm.
The flatness of the counter-face is essential, even more so when rotation speeds are high. The maximum acceptable deviation is 0.40 mm for 100.00 mm.

Axial support

Installing the V'Ring is recommended when the axial support is at full stop. This is also recommended for applications where tightening between the V'Ring and the shaft is relatively weak and where the circumferential speed will exceed 6.0 - 8.0 m/s.
The table below sets out the calculation method for the diameter of the support Ød2.
