Engineered Surfaces The engineered surfaces of the InnoFlex Self Aligning Bearing Housing cut through sticky corrosive solids, allowing the roll to operate smoothly upon start-up. The stealth surfaces of the InnoFlex Bearing Housing has multiple peaks and valleys. Solids never get a foot hold. Due to the weak bond between the Solids and the Bearing Housing, as the conveyor starts the InnoFlex bearing housing cuts through solids that build up on the flat and uneven roller end seals. Rollers with InnoFlex Bearing Technology run longer and increase production. Innoveyor is the world leader in composite idler design, they didn’t invent the idler; they made it better!
