Description
    Parker’s “L” style V seal, also called a V ring, has a narrow cross section for rotating shafts where space is limited. It is primarily used for the exclusion of dirt, dust or water as well as retention of grease or other viscous fluids. The V seal may also be used as a secondary seal to protect primary seals by excluding contamination in hostile environments.

    How it works: The seal body has a stretch fit on the shaft and the flexible lip seals against the counter face. As the shaft rotates the seal also acts as a slinger. Centrifugal force produces a decrease in contact pressure of the elastomer lip as speeds increase – keeping frictional losses and heat to a minimum.

    Standard Materials:
    • NBR; Temp -40F / +225F
    • FKM: -30F / +325F

    Shaft Surface Speed: To 1600 fpm (8.1 m/s)

    Shaft Size Range: 5.320 to 18.700 inches (135 to 475 mm)

    Maximum Shaft Dynamic Runout (TIR): Within limits of fitted width assembly dimension, B1, as illustrated in the Literature document in the Product Support tab, titled “Rotary Shaft V Seals and Excluders from Parker.”

    Maximum (STBM) Misalignment: 1 to 4 degrees

    Maximum Pressure: 0 psi

    Typical Applications:
    V seals (or V rings) are commonly used in a variety of applications including small motors, conveyors, appliances, agriculture and automotive equipment, work rolls, rolling mills, pumps, gear boxes, and pillow block bearings.
