V-rings
V-ring overview
V-rings are solid rubber seals used in shaft components. Their core function is to prevent dust, moisture, and other foreign matter from entering the sealed areas such as oil seals and housings, while also effectively preventing lubricant leakage. Their sealing principle is as follows: the V-ring stretches along the shaft to form a tight fit, with its flexible lip lightly contacting the mating surface perpendicular to the shaft, thus creating a reliable sealing barrier.
V-rings provide good sealing even when used alone. When used in conjunction with rotating shaft seals, their sealing performance is further enhanced, while also helping to extend the service life of bearings, oil seals, and shafts. Gamma Seals offer the same function as V-rings, but with the addition of a metal outer shell structure, providing extra protection for the seal.

Benefit
- Easy and efficient installation: Almost no complex preparation is required. Simply ensure the shaft surface is clean, apply a suitable amount of lubricant to the V-ring lip, and then slide it along the shaft until the flexible lip is fully engaged with the mating surface. Only minimal pressure and friction are needed to achieve a tight seal with the mating surface.
- Economical, practical, and cost-effective: A wide tolerance range allows a single V-ring to be compatible with various shaft diameters, while effectively compensating for significant misalignment and eccentricity errors in the shaft. The product boasts excellent durability, resulting in a longer service life and reduced risk of damage during installation, thus lowering overall operating costs.
- Wide range of applications: Performs excellently in dry environments, rotary shafts, and oscillating shaft applications, suitable for speeds exceeding 3000 FPM.
Options
We offer three styles (VA, VC,
VS and VL) and three materials for V-rings: NBR (black) and FKM (brown).
VA : This is the most widely used standard model, with a wide size range, from 2.5 mm to 1810 mm in inner diameter. This model features a short installation length, compact structure, and is suitable for dustproof sealing of shaft ends in gearboxes, motors, and various drive devices.
VC: The dimensions of VC oil seals are marked using the standard method of shaft diameter × outer diameter × width, with the unit uniformly in millimeters (mm). This is a globally accepted industrial marking standard.
VS : With an inner diameter range of 4 mm to 180 mm, it offers strong dimensional accuracy and adaptability, and is primarily used for shaft end sealing applications in agricultural machinery and the automotive industry.
VL :This series of products has an inner diameter ranging from 99 mm to 540 mm, features a short installation length, can meet the needs of sealing space constraints, and can also be used as part of a labyrinth sealing system.
