Piston Ring Rotation

 

Find Suppliers by Category

Dynamic seals include oil seals, hydraulic and pneumatic seals, exclusion seals, labyrinth seals, bearing isolators, and piston rings. They create a barrier between moving and stationary surfaces in applications such as rotating shafts and pistons rings.  This is a general search form; more detailed search forms are available.

  • Low Noise, Increased Reliability, Digital Control: A New Generation of Radial Piston Pumps
    (right). Fig. 7 shows on the left side a radial piston pump with a rolling stroke ring. Under certain. conditions (small pressure, high viscosity) the stroke ring tends to an uncontrolled. rotation. This leads to friction and might lead to wear on stroke ring, housing and servo. piston slipper pads
  • Rotary Actuators
    , the outer spline engages the ring gear and causes sleeve rotation. At the same time, the inner spline engages another set of helical teeth on the output shaft. This causes relative shaft rotation in addition to that of the piston sleeve. increase helix angle and reduce actuator length by replacing
  • Get Reliable Results From Rubber Test Data
    component deals with temperature and the material's behavior over its lifetime. Add to this manufacturing tolerances characterized by minimum and maximum material conditions (LMC and MMC). An O-ring application, for example, involves sealing over the life of a device when it is minimally loaded at LMC
  • MICRO: Product Technology News (February 2001)
    . Resolution lens options of 1.0 and 2.0 um are offered, which are designed to meet the needs of simple and advanced ABS designs. A touch screen interface and customized hardware and software ease operation. The Model 761 ion chromatography unit combines an injection valve, serial dual-piston pump, column
  • Vacuum pumps
    pumps cannot produce high levels of vacuum, they provide high flow rates. Principal types of positive-displacement vacuum pumps include piston, diaphragm, rocking-piston, rotary-vane, lobed-rotor, rotary-screw, and liquid-ring designs. Reciprocating-piston pumps generate relatively high vacuums
  • Magnetostriction in Automotive Position Measurement
    magnetic field is formed. by a position marker magnet. The position marker magnet is attached to whatever is being measured, perhaps. a piston in a strut. The waveguide wire is enclosed within a protective cover and is attached to the sta-tionary. part of the machine, perhaps a strut cylinder body
  • Slick as a whistle, hard as a rock
    seal and helps the seal resist wear from the chrome-plated seal ring. Extending the life of the seal found on F-14 Tomcats, F-15 Eagles, F-16 Falcons, and the new F-22 Raptor reduces costly and time-consuming replacements that involve tearing down almost the complete engine. Variable vanes: Another
  • MICRO:January 1998:Product Technology News
    components include piston slides, eccentrics, rotor assemblies, and shafts for pumps made by Alcatel, Busch, Edwards, Kinney, Leybold, Stokes, and Welch. The components are refurbished to meet or exceed OEM specifications and come with a one-year warranty. Worn areas are rough-machined to prepare a good
