✵ The Mechanics of Axial Centrifugal Sealing ✶

Protecting Bearings via Kinetic Synergy

Unlike radial oil seals that wear down shafts through constant friction, the Industrial V-Ring Seal mounts directly as a tension-fit on the shaft and rotates with it. The flexible lip creates a dynamic axial seal against the counterface.

◌ Centrifugal Slinger Effect: Actively rejects mud, water, and debris away from the bearing via rotation speed.
◌ Low Friction Torque: Minimal axial pressure reduces power loss and heat generation compared to lip seals.
◌ Misalignment Capacity: Accommodates significant shaft tilt and run-out without compromising the barrier.
◌ Zero Shaft Wear: Because the seal rotates with the shaft, there is no abrasion or grooving on expensive components.

VA, VS, and VL Profiles Selections

✬ VA Profile (Standard)

The most common type with a straight back, suitable for standard shaft diameters from 3mm to 2000mm.

✬ VS Profile (Heavy Duty)

Reinforced wide back for applications requiring a tighter grip on the shaft at higher rotation speeds.

✬ VL Profile (Compact)

Ultra-slim profile designed for compact housings where axial installation space is severely restricted.

V-Ring Technical Q&A

Q: What counter-face surface finish is recommended for VA/VS seals?
For optimal performance, we recommend a surface roughness of Ra 0.4 to 0.8 μm. For high-speed applications, a polished surface prevents premature lip wear.

Q: How do I choose between VA and VS profiles for my shaft?
VA is the standard profile for most general shafts. VS should be selected for larger shafts or higher RPMs where the reinforced back provides a more secure tension-fit.
