V-Rings for challenging requirements
V-rings are rotary seals that can perform numerous jobs in their function of sealing rotating shafts:
- sealing against the penetration of dirt, dust, water or watery pollutants,
- combination with other sealing elements, e.g. the protection of a radial shaft sealing ring against external contamination,
- or sealing against grease leaking from a housing.
Advantages of V-Rings
- diverse fields of application
- no high requirements as regards the shaft and housing designs
- low friction
- high circumferential speeds are possible as a result of reduced friction
- relatively insusceptible to coaxiality and radial eccentricity
- long service life
- easy installation
Construction types/designs
In order to cover the wide range of possible applications, we have 3 standard designs in stock, made of 2 different materials each (NBR and FKM).
VR-A10
Dimensional range in stock: 3 - 1000 mm,
>1000 mm on request,
most commonly used standard design with straight sealing back
VR-S10
Dimensional range in stock: 5 - 199 mm,
the same design as VR-A10 in the lip area,
complemented by a conically extended retaining part, thus providing a better seat on the shaft
VR-L10
Dimensional range in stock: 110 - 600 mm,
>600 mm on request,
small profile geometry for compact installation conditions, uniform profile for all diameters
Materials
We offer V-rings from stock made of NBR and FKM and other elastomers, such as CR, EPDM and HNBR, on request.
NBR 60
- standard material for a wide range of applications
- thermally resistant between -40 and +100°C
- good wear and abrasion resistance
- resistant to many media, such as mineral oil based oil and grease, water
FKM 60
- applicable under higher temperatures and in the presence of more aggressive media
- thermally resistant between -20 and +200°C
- very good resistance against many chemicals
- very good aging, ozone and weather resistance
