Flat Idler Pulley, 3-1/4"X3/8"X7/8"W

Flat Idler Pulley, 3-1/4"X3/8"X7/8"W

The 280-586 Flat Idler Pulley is a heavy-duty metal idler pulley designed as a direct replacement for a wide range of OEM part numbers used on lawn and garden equipment. With a 3-1/4" OD and 3/8" ID, it’s built to keep belts tracking smoothly and tensioned properly—because a squealing belt is the machine’s way of complaining loudly.
