VLX Ring Seal & VLX Ring Size Chart
Building on the VL series, the VLX ring introduces a revolutionary 0.8mm ultra-thin cross-section, achieving 65% axial space reduction versus conventional designs. Its inner diameter spans 126–1810 mm (for shafts 140–2000 mm), with a dual-lip configuration enhancing sealing redundancy. The fluorosilicone compound enables operation at -50°C to 200°C, ideal for aerospace actuators and semiconductor wafer handling robots where micron-level space constraints exist.

The most commonly used materials for VLX Rings are nitrile NBR and FKM/Viton. And the hardness (durometer) of NBR and FKM rubber is generally 60 Shore A. HNBR, EPDM, and PTFE are rarely used in some special scenarios.
1. NBR – Excellent oil resistance, good elasticity, suitable for mineral oil, grease and other media, the working temperature is generally -40℃～100℃. Widely used in the seals of automobiles, bearings, pumps and other equipment, and is a common material for V-type water seals (such as VA type, VLX type).
2. FKM/Viton – High temperature resistance (up to 200℃), strong chemical corrosion resistance, suitable for harsh media such as synthetic oil, acid, alkali, etc. Used for water seals in high temperature or chemical corrosion environments (such as VA type, VLX type).
3. HNBR – Hydrogenated and modified based on NBR, the temperature resistance is significantly improved (-40℃～150℃), while retaining excellent oil resistance, and stronger oxidation resistance and chemical corrosion resistance. Suitable for sealing scenarios with higher temperatures or chemical environments, such as high-temperature oil pressure equipment, chemical pumps, etc.
4. EPDM – Outstanding water and steam resistance, temperature resistance range -40℃～150℃, suitable for non-oily media such as water and air. Used for sealing in water treatment equipment or humid environments.
Depending on the different material, the VLX ring can be used in the following working conditions:
Speed: ≤19m/s; Pressure: ≤40MPa; Temperature: -40℃～+200℃; Medium: mineral oil, air, water, emulsion, grease, etc.
