In order to understand the reliability situation of linear rolling guide,characteristics and reliability test were studied. By the analysis on indicators and influencing factors of precision maintenance,function reli-ability and fatigue life reliability,the linear rolling guide reliability test design was put forward. Test samples was extracted in the same batch of the same types of rails at random. This testing scheme mainly considered from three aspects including test conditions,failure criterion and assessment method;obtained the guide preci-sion characteristics,functional reliability and service life characteristics. Finally, analyzed the various faults of linear rolling guide from the reliability test.
