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 *0,**0 hours) and high reliability. We invented
controllable braking idlers, which can solve the problem of
controllable brake along the line of large downward belt
conveyors. Technical
feather 1.High-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 *5#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. 8.The idlers can meet DIN,JIS, CEMA and ISO
standards
