Bidirectional friction taper aligning idler has many advantages:

1 has the advantages of simple structure, compared with the DTII type without connecting rod mechanism, does not appear to link the death card pin broken accident;

2 flexible rotation, intermediate shaft double bearings and seal design, dustproof, anti rust, small frictional resistance;

3 high reliability, arc cone friction wheel design can prevent the conveying belt deviation range than allowed, axis card can prevent roll off;

4 long life, anti rust and dust home butter cup design can prolong the self-aligning roller service life, arc cone friction wheel will not scratch the conveyor belt;

5 the use of a wide range, not only can be installed in a two-way running belt conveyor belt conveyor and can be installed in the one-way operation, especially suitable for with a concave arc or a bucket wheel stacker reclaimer belt conveyor.
