One end of the pin is provided with a main lubrication filling hole. Inside the roller, there is a chain smooth fitting groove. At both ends inside the chain smooth fitting groove, there are running smooth fitting bearings respectively. Between the two running smooth fitting bearings, there is an isolation safety fitting sleeve. At the center axis position of the isolation safety fitting sleeve and the fitting position with the sleeve, there is a cylindrical lubrication fitting oil storage groove. Both sides of the lubrication fitting oil storage groove communicate with the running smooth fitting bearings. Inside the main lubrication filling hole, there is a lubrication fitting conveying hole communicating with the lubrication fitting oil storage groove. At the outer side position of the running smooth fitting bearing, there is a bearing sealing fitting cover.
