How Long Before Overhaul For Jet Engines?
25/2/2007· All jet engines have life limited parts. Most rotating parts have a cycle limitation, typically 20000 cycles for a disc. When this limit is reached the engine must be removed and reworked. But as other posters have said, the RB211-535 and the CFM56 are renowned for long time on wing. 10 years on the wing is not unknown.

Model gas jet turbine bearings - AHR International
These bearings are stable from 750 to 800 degrees C (way beyond normal lubriion limits and bearing steel limits). With reduced weight, reduced ball inertia and massive improvements in low lubriion scenarios these full ceramic possibilities offer significant improvements on component life, especially when you consider what happens to various engine components when …
Technical Information: Ball bearing types, selection factors, and bearing …
Ball Bearings. There are several types of ball bearings that fit specific needs. The deep-groove ball bearing, Figure 2 (a), is the most versatile. Radial loads and thrust-load capacities may be approximately equal in this bearing. When it has the proper separator, it is very good for high-speed operation.

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 …
