These 6061-T6 billet idler bearings are a big upgrade from the plain stamped steel versions that the OEM uses. Traditionally the 89052 idler from Dayco was the go-to for 6 rib applications, and we used the Continental 49102 for 8 rib configurations. The issue was cost, lead time, and quality. We decided to step up and make our own in house, so that none of that would be an issue any longer. There are a few options for these idlers, so pay attention.
The overall design of this idler will accomodate either a 6 or 8 rib belt width. You have a bit more "wiggle room" in 6 rib, before the gates at the side of the pulley are used. You MAY have to shim the idler back or forth, depending on what idlers you have now, and if they are different than a Dayco 89052. If you are running an 8 rib setup with 49102 idlers, contact us and we can get you sorted.
The idler comes in 2 flavors, Heavy Duty, and Super Duty. The overall design is the same, but the Heavy Duty uses a single row bearing, much like the OEM parts, which is fine for 99% of the applications out there. The Super Duty version comes with a double row angular contact bearing, for extra stability. Both versions are press fit bearings, and use a C-Clip as a second retention method for the bearing.
Idlers are stocked in HD and SD for in BLACK ONLY!!!!! If you want one in clear anodize, or any color, we CAN do this, it might just take a few extra days. Please put the color in the notes, or contact us BEFORE ordering if you are in hurry, and we will try to accommodate you. Custom engraving is also available.
