“…Therefore, investigating the effects of a defect in the outer race on the vibration behavior of the ball bearing produced with a 3D printer and its lifetime is essential for ball bearing and the performance evaluation of 3D printers. In literature, although many researchers have focused on production methods and production parameters of 3D ball bearings (Harikrishnan and Soundarapandian, 2018;Mizobe et al, 2019;Mizobe et al, 2018;Lee et al, 2018aLee et al, , 2018b, there is no comprehensive study about the lifetime of 3D-printed ball bearings with outer race defects. This study investigated the effect of an outer race defect on the vibration characteristics of a polymer hybrid ball bearing manufacturing with a 3D printer and its lifetime.…”

Purpose In industry applications, polymer hybrid bearings have become widespread in recent years owing to the lack of lubricant requirements, particularly in areas requiring hygiene. The additive manufacturing method gives significant advantages to have complex machinery parts, and it has become popular in the industry in recent years. However, it has some inherent disadvantages caused by layered deposition/addition of the materials, and the probability of the localized defect is much higher than in the conventional manufacturing methods. This study aims to investigate the effect of the outer race defect on the characteristics of vibration and service lifetime of hybrid polymer ball bearings produced with the stereolithography (SLA) additive manufacturing method. Design/methodology/approach In this study, polymer bearings’ races were produced with the additive manufacturing SLA method, and the outer race defect was analyzed with measured vibrations. Findings The results show that the additive manufacturing method suggests a practical solution for producing a polymer hybrid ball bearing. On the other hand, the hybrid three-dimensional-printed bearing, which has an outer race defect, worked for approximately 8 h without any problems under a 1 kg load and a shaft speed of around 1,000 rpm. In addition, when there is a defect in the outer and/or inner race of the ball bearing, the crest factor and kurtosis of the vibration are higher than faultless ball bearing, as expected. Originality/value This paper provides valuable information on the lifetime and vibration characteristics of polymer hybrid ball bearing produced by means of additive manufacturing.
