Aircraft Reciproing Engine Bearings

Straight roller bearings are used in high power reciproing aircraft engines for the crankshaft main bearings. They are also used in gas turbine appliions where radial loads are high. Generally, a rotating shaft in a gas turbine engine is supported by a deep-groove ball bearing (radial and thrust loads) on one end and a straight roller bearing (radial loads only) on the …
