  • Rotary Seal Lip Design and Geometry
    Apart from the elastomeric lip material and interface between the sealing lip and application shaft, a critical design feature of the seal lip is its geometry. Lip geometry is one of several factors that directly affect the radial load exerted on the shaft. The others include the presence
  • Radial Shaft Seals
    operating parameters of radial shaft seals are based upon a basic design (Figure 1). A spring loaded radial lip is usually needed to retain oil or low viscosity fluids. The seal must then be correctly sized for the hardware. Figure 1. Basic seal design parameters. Surface Speed Radial seals may have
  • Exclusion Seals
    with a sealing lip at the bottom and a rod wiper at the top, so the wiper can perform as a pressure-energized lip seal inside the cylinder at the same time it wipes contaminants from the outside. The two most common types are a double-lip U-seal and a double-lip V-seal. Both are one-piece snap-in replacement
  • Felt Seals
    Unlike lip seals and squeeze packings, felt seals require relative little shaft pressure to function effectively. They are commonly used near ball and roller bearings as lubricant retainers. Advantages of felts seals include: Wool felt resists dilute mineral-acid solutions, unless continuously
  • Seal Operating Procedures
    In most lip seals, increasing fluid pressure increases lip-contact pressure. In a properly designed and installed seal, the lip rides on a thin film of lubricant. Because the film does the sealing, its thickness (usually about 0.0001 in.) must be controlled precisely by the mechanical pressure
  • Pressure-Energized Seals
    Dynamic sealing applications often call for pressure-energized seals. In the absence of system pressure, seals such as pure lip seals have only the light load of deflected lips to provide a sealing line. They have a definite tendency to seep at low pressures. As system pressure increases

  • Improved Cooling Tower Maintenance: The Cool, Hard Facts
    mechanical face-type seal alternatives that can be incorporated into new designs, or be back-fitted into designs containing lip-type shaft seals: A face-type seal consists of rotating and static members that are separated by an oil film. Typically, one member is held against the other by a spring
