  • 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
  • Ball Bearing Radial Play (Internal Clearance)
    At first glance, ball bearings are relatively simple mechanisms. However, an analysis of their internal geometries reveals that they are quite complex. For example, the ball to raceway conformity, the radial play, and the number of balls all impact the ability a ball bearing to support loads under
  • How to Maximize Retention of Spring Pins

  • SPRING PERFORMANCE - Processing Effects on Residual Stress
    . This process. is one of very few that can create a triaxial residual stress state, meaning that compressive residual stresses. are present in the longitudinal, transverse (hoop), and radial directions. While radial residual stresses may. not be significant to a spring manufacturer, the longitudinal

  • Medical Device Link .
    . This relationship also applies to the static radial stress, if the stent graft is to ensure a sufficient sealing and migration safety on the anchoring zones in an aorta. Finite element analysis (FEA) using the hysteresis data of the NiTi wires, stent spring geometry and static and dynamic compression

  • How Rings Work
    is achievable within the same space envelope. Wave Compression. X = wave height - radial gap between components. X = wave height - (inner component OD - outer component ID). 2. Component tolerance is a major factor in spring force. Wave height varies with each ring configuration within limits
