How do I measure an existing lip seal to ensure proper fitment?

Measure the rotating shaft diameter (seal inner diameter), the housing bore diameter (seal outer diameter), and the housing depth/thickness. These three dimensions (ID x OD x Width) determine the exact replacement size needed for your hydraulic system.

What is the difference between single lip and double lip rotary seals?

Single lip seals are engineered to retain oil or grease lubricant within the bearing chamber. Double lip seals add an auxiliary external dust lip to block dirt, moisture, and particulate ingress from the exterior environment, offering enhanced protection.

Is this MECCANIXITY UN Radial Shaft Seal suitable for Indian industrial conditions?

Yes, these seals are designed for demanding industrial environments and offer good resistance to dust and wear, common issues in Indian workshops. Their wide temperature range also suits various Indian climates.

How to choose the correct shaft seal size for my application?

You need to accurately measure the shaft diameter (for the inner diameter of the seal) and the housing bore diameter (for the outer diameter of the seal). Ensure the seal width also matches the housing groove depth.

What are the benefits of using PU material for shaft seals?

Polyurethane (PU) offers excellent oil resistance, wear resistance, low-temperature flexibility, and aging resistance. It provides high hardness and elasticity, making it easy to install and durable for hydraulic applications.

Can I use these shaft seals for high-pressure applications?

These seals are rated for working pressures less than 35Mpa. For applications exceeding this limit, you would need to consult specialized high-pressure seals designed for such conditions.

About this item

MECCANIXITY UN Radial Shaft Seals provide reliable sealing for industrial hydraulic cylinders. The Y-shape cross-section and 90A hardness PU material ensure excellent oil resistance, wear resistance, and elasticity. These seals are designed to prevent dust, dirt, sand, and metal debris from entering, protecting both piston and piston rod in static pressure applications. Imported directly, they offer superior performance compared to generic alternatives.

These seals operate effectively within a wide temperature range of -35°C to 100°C, at speeds under 0.5m/s and pressures under 35Mpa. Their polyurethane construction offers high hardness and elasticity, making them easy to install and resistant to aging. The blue color and precise dimensions (22mm ID x 35mm OD x 6mm Width) ensure a proper fit for various industrial applications.

For Indian industries facing demanding conditions, these imported MECCANIXITY seals offer a durable solution. They are ideal for hydraulic cylinders, hoists, and moving rods where contaminant ingress is a concern. All customs duties and GST are included in the price, with tracked delivery via ExpressBox to your pincode.

Why choose this product

Engineered for Industrial Demands

MECCANIXITY UN Radial Shaft Seals are engineered with a Y-shape cross-section and 90A hardness polyurethane for superior performance. This formulation provides exceptional oil resistance, wear resistance, and elasticity, ensuring longevity even in demanding industrial environments. Unlike generic seals, these are designed for precise fitment and robust protection against contaminants, maintaining the integrity of your hydraulic systems. Imported directly, they represent a commitment to quality and durability.

Ideal for Indian Industrial Settings

These seals are perfect for Indian workshops and factories dealing with dust, humidity, and varying temperatures. They excel in protecting hydraulic cylinders, hoists, and moving rods from abrasive particles and moisture. While suitable for most industrial hydraulic applications, users with extremely high-speed rotating shafts (above 0.5m/s) or those requiring seals for aggressive chemical environments beyond standard petroleum oils might need specialized PTFE or Viton seals.

How to use

Prepare the Housing and Shaft — Ensure the shaft and the housing bore are clean, free from burrs, and properly lubricated with a compatible lubricant. Verify the shaft diameter and housing bore match the seal's 22mm ID and 35mm OD specifications.
Install the Seal — Carefully press the seal into the housing bore. Use a seal driver or appropriate tool to ensure the seal is installed straight and seated fully without damaging the lip or the housing. Avoid forcing the seal.
Verify Sealing Performance — After installation, check for any signs of leakage or contamination ingress. Ensure the seal operates smoothly within the specified speed (<0.5m/s) and pressure (<35Mpa) limits for optimal performance and longevity.

Example scenarios

Typical situations where MECCANIXITY UN Radial Shaft Seal 22mm ID x 35mm OD x 6mm Width PU Oil Seal helps — illustrative scenarios, not customer reviews.
