• Nitrile skeleton oil seals consist of nitrile rubber as a sealing lip material and a metal skeleton. Nitrile rubber has excellent oil resistance, wear resistance and elasticity, making it especially suitable for environments with mineral oils, hydraulic oils and other media. The metal skeleton provides structural support and ensures that the oil seal maintains its shape and increases overall during installation and operation.
• Its sealing function is mainly achieved by the close contact between the rubber lip and the shaft surface. The lip design usually has a return oil line that can direct the penetrated oil back to the oil tank while preventing the penetration of dust, moisture and other impurities from the outside, This achieves a double-sided sealing effect. During installation, the lip should face the side of the sealed medium to ensure more reliable sealing under pressure.
• Nitrile skeleton oil seals are suitable for mechanical transmission applications with medium to low temperatures (generally -30 ° C to 100 ° C) and medium speeds, such as. B. Car engines, transmissions, hydraulic pumps and engine bearings. Due to the low resistance of nitrile rubber to polar solvents, it is not suitable for use in environments with strong chemical corrosion.
• s: Low cost, good oil resistance, excellent elasticity, certain for shaft eccentricity and vibration, and easy installation and maintenance.
• When selecting a seal, it is important to match the shaft diameter, groove dimensions, and working medium to ensure that the lip hardness meets the operating conditions. During maintenance, avoid scratches or excessive wear on the shaft surface. Regularly check the oil seal for lip wear, deformation or corrosion of the skeleton. If a leak is detected, replace the seal immediately to extend the service life of the device.
