  • Exterior coatings producer blends abrasives with no shaft seal wear
    A manufacturer of stucco and exterior coatings uses a Munson ribbon blender to meet the challenge of blending heavy, abrasive aggregates non-stop, all day, without premature seal leakage.
  • Creating a Perfect Oil Seal
    A good oil or radial shaft seal is designed to either keep oils or other fluids from leaking out of a mechanical component or to keep contaminants from finding their way in, and many times both.
  • Extending Seal Life Starts with Proper Selection
    Although not often the most expensive component in a bearing assembly the proper selection of the radial shaft seal can be crucial to ensuring bearing longevity and reducing system maintenance costs of gear boxes, pumps, motors and other power transmission devices.
  • An ACS Crash Course on Seal Types for Rotary Valves
    One seal, two seals, packing gland, shaft seal. The choices are seemingly endless for the types of seals that work with your rotary valves and airlocks. And, just so you don't have to go through the same dilemma of which seal to choose every time they need replacing (which they will), here's your
  • Seal Eccentricity (.pdf)
    The two major elements of eccentricity that should be considered when designing a seal: Shaft-to-Bore Misalignment(STBM) and Dynamic-Runout(DRO).
  • Radial Shaft Seals
    system. Seals - particularly radial shaft seals - have a profound effect on the longevity and performance of a pump system. Rubber radial seals provide economical and versatile protection for bearings in pumps, gearboxes, and motors. Their contact with the shaft offers both positive fluid retention
  • Seal Operating Procedures
    of the seal element and the shaft finish. If the film gets too thick, fluid leaks. If too thin, the lip wears, friction increases, and stick-slip oscillations can result. Stick-slip oscillations cause a surface wave in the seal, which permits leakage. Aside from mechanical pressure, the main factors
  • 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
