The Negotiator™ Self Aligning Return Idler is an innovative concept in self aligning return roll design. The cutting edge design is for the most difficult belt training applications where conventional self aligning idlers have not been able to help with belt tracking.


Design Features:
•Unique three roller design helps center the belt better than conventional rolls
•Self cleaning frame design helps to prevent material build up by shedding carry-back from the return side of the belt
•Three roll design offers a support bed that cradles the belt and more efficiently reacts to the pressure of the side guide rolls
•Three roll design decreases shaft deflection and increases bearing life inside the roll when compared to conventional single roll return idlers
•Rubber discs help to shed material and prevent material build up on the rolls
•Can be used with reversing belts
•UHMW side guide rolls have the lowest possible coefficient of friction and help to prevent belt damage
•Side guide rolls are strategically positioned to help prevent the belt from contacting the brackets
•Lower profile design is ideal for those tight to fit applications
•The mounting brackets are vertically adjustable ± 1” providing an additional tracking aid


Complies with MSHA Title 30 CFR:
