VA type:The most common style available in the widest range of sizes from .110″ (2.7mm) shaft to 79.530″ (2020mm) nitrile and fluoro elastomer. Ideal for protecting gearboxes, electric, motors and drives.
VS type：The original V-ring designed with a wide body and tapered heel to firmly hold the ring on the shaft. Available in sizes from .180″ (4.5mm) shaft to 8.270″ (210mm). Commonly used in agricultural and automotive applications
VL type：Very compact axial cross-section commonly used in confined spaces to replace labyrinth seals. Available in nitrile and fluoroelastomer for shaft sizes from 4.134″ (105mm) shaft to 78.745″(2000mm) and beyond.
VE type：A heavy-duty large diameter style commonly used in rolling mills as a secondary seal for heavy duty applications where the primary seal has to be protected against water and or particulate contamination. VR4 is the preferred heavy duty. Available in both nitrile and fluoroelastomer for shafts from 11.811″ (300mm) to over 78″ (2000mm).
Installation
Where the V-ring is used as a grease seal/contaminant excluder, the V-ring is normally mounted on the outside of a bearing housing with axial support when required.
In the case of mass production, it is always advisable to use an assembly tool. Where small quantities are
involved the V-ring may be fitted by using a blunt instrument, such as a screw driver, to manipulate the
seal into the correct position.
General rules:
1. The V-ring, the counter face and the shaft should be clean.
2. The shaft should preferably be dry and free from grease or oil.
3. The lip of the V-ring should be lubricated with a thin film of grease or silicone oil.
4. Ensure that the V-ring is mounted with a uniform stretch around the shaft.
