V-Ring Axial Shaft Seals

V-Ring Axial Shaft Seals are flexible, all-rubber sealing rings designed to protect bearings, rotary shafts and other mechanical components from dust, dirt, water splashes and external contaminants. They are commonly used as secondary seals in industrial equipment, particularly where bearing protection and contaminant exclusion are important.

Unlike conventional radial shaft oil seals, V-Rings are mounted directly onto the rotating shaft and rotate with it. Their flexible sealing lips make axial contact with a stationary counterface, such as a bearing housing, metal flange or machine component.

This sealing arrangement provides effective contamination protection while accommodating a certain degree of axial movement, shaft misalignment and dimensional variation.

Features & Advantages

• Axial Sealing Design: A flexible lip seals against a stationary surface perpendicular to the shaft.

• Contaminant Protection: Helps prevent dust, dirt, grease-borne particles and water splashes from entering bearing assemblies.

• All-Rubber Construction: Flexible elastomeric design without a conventional metal case or garter spring.

• Easy Installation: The elastic ring can be stretched over the shaft without requiring a press-fit housing bore.

• Low-Friction Operation: Light lip contact helps reduce friction, while certain high-speed designs can operate with reduced lip contact.

• Flexible Shaft Positioning: Accommodates limited axial movement and shaft misalignment depending on the seal profile.

• Additional Bearing Protection: Can be installed alongside radial shaft seals to provide an extra barrier against contamination.

Material Options

V-Ring seals are commonly manufactured from NBR and FKM elastomers, with EPDM, HNBR and other specialty compounds available for selected applications.

NBR provides good resistance to mineral oils and greases and is widely used in general industrial equipment.

FKM offers improved heat resistance and compatibility with many oils, lubricants and selected chemicals.

EPDM is suitable for water-related applications and environments exposed to ozone or weathering, while HNBR provides improved heat and aging resistance compared with conventional NBR.

Material selection depends on the operating medium, temperature, shaft speed and environmental conditions.

Common V-Ring Profiles

V-Rings are available in several profiles to suit different shaft diameters, installation spaces and sealing requirements.

Common configurations include VA, VS, VL and VE types. VA is widely used for general bearing protection, while VS provides a wider body for secure positioning. VL is designed for applications with limited axial space, and VE is suitable for larger shafts and demanding industrial environments.

Typical Applications

V-Ring axial shaft seals are widely used in:

• Electric motors and industrial drives

• Gearboxes and speed reducers

• Bearing housings and assemblies

• Agricultural and construction machinery

• Pumps and industrial rotating equipment

• Conveyor systems and material handling equipment

• Heavy-duty industrial machinery
