Know your thrust bearings
pump to provide oil-film pressure when simple, internal hydrodynamic pumping action cannot generate sufficient force. Primary use is in equipment run at extremely low speeds, under high loads, with low viscosity fluids, or where space is limited. A compact thrust bearing can feed high-pressure oil

Keeping Thrust Bearings Cool
oil-film pressure that supports greater bearing load, sometimes up to 300 psi. For typical “square” segments where radial length L equals circumferential breadth B, the optimum step location is at 50 to 55% of B from the leading edge of the segment. Step height should be 0.7 times the trailing edge film

Thrust Ratings and Dimensional Data (Metric)
Shafer L-Series linear actuators are custom engineered to match the specific application requirements of stroke length, thrust, and power pressure. Due to the vast number of combinations offered by valve manufacturers, little standardization is allowed. Linear Metric DD THRUST RATINGS

It's a swing and a miss
cylinder retracts, the gate swings open and pressure thrusts the ball down the barrel and propels it out of the tank. The spin mechanism consists of a retractable suction cup, a dc motor with a tachometer and drive belts, and pneumatic controls. The suction cup is an aluminum cylinder fitted

Betting Big on Business Aviation
officer, the exact architecture of the eCore will vary depending on the application size. An artist's rendering of the core, actually lofted from digitized engineering blueprints, depicts a 10-stage high-pressure compressor driven by a two-stage HP turbine. Noteworthy are the smaller number of airfoils

Hydrostatic Bearings
Designing hydrostatic bearings is more complex than for self-acting types because of the greater number of components requiring design decisions. The pressure pads in hydrostatic bearings carry the load. Most hydrostatic systems (thrust or journal bearings) use several evenly spaced pads so

Metraloop Solves Pipe-Guiding Dilemma for Hotel
, we instead recommended the Metraloop(R) expansion joint," Hesterman explained. "Since the Metraloop required no guiding, and exerted no pressure thrust loads, it was the perfect solution.". The Metraloop expansion loop has none of the pressure thrust loads of conventional bellows-type joints
