As one of National Innovation Fund Project, LIBO idlers are of complete sealing waterproof and dustproof design, whose bearing assembly employs high-precision bearing chamber and special bearings for idlers, which provide fine appearance, low noise, free maintenance, long service life(exceeding 50,000 hours) and high reliability. We invented controllable braking idlers, which can solve the problem of controllable brake along the line of la-rge downward belt conveyors
Technical feather of our product as following;
1.accuracy and high frequency welded pipe is selected as the shell, which enjoys less diameter run-out and better balance;
2.Stamping parts are used as bearing housing, which are machined by NC lathe;
3.The bearings are KA serial special bearing for idlers
4.The material used for bearing shafts is high-strength 45#steel, and NC turning and grinding can ensure precision.
5.The sealing is specially designed with abilities of self-compensation, low resistance, waterproof and dustproof, which can keep bearing in good lubricated condition for a long time.
6.Seamless steel pipe is selected as the shell of impact idlers, with thick wall and high strength;
7.The rubber ring of impact idlers is made up of flame retardant rubber.
