Chicago Rawhide V-Ring Seals

V-ring seals are unique all-rubber seals for rotary shafts. They are made entirely of rubber material and comprise a body and a conical shaped sealing lip, which is joined to the body by means of a resilient “hinge”.

V-rings are mounted on and rotate with the shaft. The lip seals axially against a counter face, which is perpendicular to the shaft. The body has an interference fit on the shaft and holds the lip in position. V-rings can be stretched out and fitted over a flange during installation, which is a very valuable characteristic, especially in the case of repair. They can operate at sliding velocities up to 8 m/s. At velocities above 8 up to 12 m/s the V-rings need to be axially located.

V-ring seals are available in a large variety of designs and sizes to fit the requirements of most applications. V-rings are normally made of nitrile rubber. For applications where higher temperatures occur or where aggressive media are present, V-rings made of fluoro rubber should be used.

Series VR

V-ring seals are available in four standard designs and two large size heavy-duty designs.

• VR1 design: Most common V-ring with normal cross section and straight backside face. Available from stock for shaft diameters from 2,7 up to 2 020 mm (0,11 up to 80 inch).
• VR2 design: V-ring with normal low cross section and a tapered back face but wide body, providing a very firm hold on the shaft. Available from stock for the most commonly used shaft diameters, which range from 4,5 to 210 mm (0,18 to 8,3 inch).
• VR3 design: Narrow low-section V-ring intended for the use in compact sealing arrangements or labyrinth seals. Available from stock for shaft diameters in the range from 135 up to 630 mm (5,3 up to 25 inch).
• VR4 design: Wide high-section V-ring designed as a secondary seal for heavy-duty applications where the primary seal has to be protected against water and/or solid contaminants. It permits the largest axial displacements. Available from stock in the diameter range from 450 up to 2 010 mm (17,7 to 80 inch).
• VR5 design: Wide low-section heavy-duty large diameter V-ring, which can be axially located on the shaft using a standard clamping band. Primarily intended for large, high-speed applications, like rolling mills and paper mills. Detailed information on request.
• VR6 design: Heavy-duty large diameter V-ring for extended axial displacements, which can be axially located on the shaft using a standard clamping band. Primarily intended for large, high-speed applications, like rolling mills and paper mills. Detailed information on request.
