Oil Seal VMQ 105x135x9 TC - Silicone Rotary Shaft Seal

Applications

The VMQ 105x135x9 TC oil seal is engineered for demanding industrial applications, including hydraulic systems, automotive drives, and engine shafts. As a silicone rotary seal, it is ideally used in high-temperature environments, low-friction shafts, gearboxes and high-speed equipment where both oil and grease resistance and reliable sealing under dynamic rotation are required. This shaft sealing ring excels in factory automation, conveyor systems, agricultural machinery, and vehicle driveline assemblies.

Advantages and Features

• VMQ/Silicone material offers exceptional flexibility at low temperatures and high thermal stability up to elevated operational limits, ensuring high durability and long service life.

• TC design (double-lip oil seal) - primary sealing lip retains lubricant; secondary lip excludes contaminants such as dust, debris and water ingress.

• Resistance to oils, greases and fuels - ensuring stable performance in lubrication-intensive environments and guaranteeing a technical seal solution for both industrial and automotive seals.

• Compact dimensions 105 mm inner diameter x 135 mm outer diameter x 9 mm width, making it suitable for retrofit and OEM applications in tight radial spaces.

• Designed as a rotary seal to minimise leakage under rotational motion, maintain equipment uptime and reduce maintenance costs.

Main Description

The Oil Seal VMQ 105x135x9 TC represents a high-precision solution for demanding mechanical systems requiring a rotary shaft seal with superior thermal and chemical resistance. Constructed of VMQ (silicone) rubber, this seal retains elasticity in extreme cold start conditions and maintains structural integrity under sustained high temperatures. Its double lip oil seal design addresses two critical functions: the main lip ensures retention of lubricant inside the equipment, while the secondary lip prevents ingress of contaminants from the external environment, effectively extending the service life of bearings, shafts and housings.

In applications such as hydraulic drives, industrial gearboxes, engine couplings and agricultural machinery, standard seals often fail due to temperature extremes or exposure to oil, grease and varying contaminants. By using the VMQ 105x135x9 TC seal, engineers gain a technical seal solution tailored to these challenges. The dimensions match typical retrofit requirements, and the robust material supports both industrial and automotive seals sectors.

Installation of this shaft sealing ring is straightforward with the correct radial tolerance, ensuring a minimal leak path and optimal rotational sealing performance. With the right shaft preparation and lubrication, the VMQ seal becomes a long-term component within your equipment management strategy, offering fewer replacements and lower maintenance costs.

FAQ

1. What is the difference between a double-lip and single-lip oil seal?
A single lip focuses on retaining lubricant, while a double lip (TC) also provides protection from external contaminants, improving seal lifespan.
2. When should I choose a silicone (VMQ) versus NBR material?
Silicone (VMQ) is chosen for high and low temperature extremes and where flexibility is needed; NBR suits standard industrial conditions with mineral oil exposure.
3. How to select the correct shaft seal size?
Match the inner diameter to the shaft, the outer diameter to the housing bore, and the width to the available axial space. Verify material and lip design for the operating environment.
4. Can this seal be used for automotive wheel hubs?
Yes, provided the dimensions and environment meet the specification. The VMQ material, shaft sealing ring design and oil/grease resistance make it well-suited for vehicular applications.
