Daemar supplies V-rings that prevent contaminants from entering oil seals

Four models of V-rings are available from Daemar.

Essential components for industry: this is the specialty of Daemar Inc. One example is four series of V-rings: solid, axial shaft seals that use centrifugal slinger action to prevent contaminants like dirt and moisture from entering oil seals and their housing. Also designed to keep lubricants in, these components work best in pressure-less application use, and they are popular in such applications as rolling mills, agricultural machinery, and electric motors.

Resistance to grease, mineral oils

V-rings function by rotating with shafts and holding themselves in position by their flexible fits on the shafts. The contact between the seal lip and counterface induces the seal. While V-rings work well on their own, they are usually combined with radial shaft seals and other seals, or used as pre-sealing material for bearings.

These versatile units have many benefits; they reduce wear in oil seals, shafts, and bearings, and they have minimal torque drag and heat buildup, with no need for expensive counter-surface preparation. V-rings function well in dry tasks, on spinning or oscillating shafts, and at speeds higher than 3,000 feet a minute.

Since V-rings are rubber and elastic, they can be stretched easily over flanges and other components for easy installation, with minimal equipment disassembly. The lip presses against the counterface with little friction or pressure. The wide toleration allows one V-ring to fit different shaft sizes and resolve shaft misalignment and eccentricity; its durability ensures long life and no installation damage. V-rings come in Buna N and Viton, and units made of NBR and FKM have wide temperature ranges and provide good chemical resistance to many greases and mineral oils. Daemar supplies these four models:

• VA – standard V-ring with a straight back for shaft from three millimetres to two metres. Ideal for appliances and conveyor rollers.
• VE – heavy-duty design for large-diameter applications. Often employed as a dirt/water excluder seal in rolling mills.
• VL – narrow cross-section for limited spaces. Perfect for pillow-block tasks.
• VS – recommended for high-speed applications, with its angled back. Popular in the automotive and agricultural industries.
