Return to Idlers home page.The NEGOTIATOR™ Self Aligning Return Idler

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
