  • Profiled Leading Edge Groove Tilting Pad Journal Bearing for Light Load Operation (.pdf)
    in diameter tilting pad journal bearings. This configuration yielded a design with projected bearing loads of less than 25 psi, and journal surface speeds that could approach 400 ft/sec.
  • Optimization of a Leading Edge Groove Tilting Pad Journal Bearing for Application in a Small, High Speed Multi-Stage Steam Turbine (.pdf)
    in. diameter tilting pod journal bearings. This configuration yielded a design with projected bearing loads of less than 25 psi, and journal surface speeds that could approach 400 ft./sec. Under these conditions, the applicable limits of conventional style tilting pad journal bearings are stretched
  • Bearings That Lube for Less
    bearings will operate in the real world. At the design phase, the engineer is relying on the strength and oil capacity of the bearing to meet, if not exceed, the design requirements. Any bearing selection process should first evaluate the maximum pressure (P) in psi exerted on the bearing
  • Good Vibrations
    , and a series of tiny holes, or capillaries, restrict the flow of air to the bearing surface. Our ET-2 tonearm has a hard-coat anodized-aluminum spindle that floats inside the manifold on a thin layer of air. A small diaphragm air pump consumes about 15 W and delivers 3.5 psi with 120 in.3/min of airflow
  • Bearings take the heat
    alloyed with a metal such as copper, babbitt, bronze, or nickel. Speed and load limits are set by a conventional = bearing load in psi and = shaft speed in surface ft/min. is about 12,000 for dry operation
  • Plane Bearings That Grease Themselves
    bearing. However, nonmetallic bearings need some special design attention. All bearings are rated for maximum loads or pressures ( ), expressed as psi, maximum speeds ( )
  • Know your thrust bearings
    loads. Unit loading on such bearings is usually limited to about 0.5 to 0.75 x external pump feed pressure of up to about 5,000 psi. The other five thrust bearing types internally generate oil pressure (self-acting) to support thrust loads. Here, a rotating face or shaft collar pumps oil onto
  • Ferrous P/M
    parts from just about any metal, the most commonly used metals are the iron-based alloys. Low-density iron P/M parts (5.6 to 6.0 gm/cm >=), with a typical tensile strength of 16,000 psi, are usually used in bearing applications. Copper is commonly added to improve both strength and bearing properties
  • Molasses
    and livestock feed. It can also be used as a raw material for various industrial alcohols. The viscosity of molasses can vary from 500 SSU at 100 °F. to 5000 SSU at 100 °F. Typical differential pressure is around 60 PSI. With a specific gravity of 1.45, suction lift conditions are critical. Often
  • Motion control on a budget
    , bearing requirements, end stops, and related hardware they need. This saves considerable design time when zeroing in on the most-effective and economical unit for the job. Here's a closer look at each factor. . Calculate a linear slide's output force = available air pressure in psi and = cylinder piston
  • Scanning for Ideas: A Motor Pump Built for Solar Power
    . It consists of a hemispheric rotor and impeller that sits on a hard, wear-resistant ceramic ball. There are no conventional shaft bearings or seals, which eliminates play in the bearings and the resulting noise. The ceramic ball, acting as a self-aligning bearing, is lubed and cooled by the fluid
  • Quick-Action Couplers
    to 10 in. diameter. They can typically handle 3,000-psi pressures. Some connectors cannot accept pressures this high; a trade-off is necessary to obtain other important operating characteristics. Self-sealing couplers can be used in any part of a system where the pressure-drop rating on the coupler
