Abstract In order to improve the working capacity and life of bearing units, dimensional analysis inner geometry a cylindrical radial was carried out. The assembly component, composed by outer diameter dimensions raceway race, race two diameters rollers, considered as dimension chain. It is recommended, in reduce wear friction losses, produce diametrical roller according fifth accuracy degree. ...

Compressor reliability and durability testing has historically required significant time and a variety oftest methods, including basic materials and lubricants testing using Falex test methods or equivalent, long term compressor bench tests, end product reliability tests and final field trials before production release. Reducing the total design cycle time to a minimum, while maintaining a high...
