Belt type AT10 polyurethane timing belts

10mm pitch · AT high-power teeth · Steel-corded PU

AT10 belts are polyurethane timing belts with steel tension cords and a larger, stiffer tooth than T10, giving more tooth contact on the pulley. That means higher power, less backlash and more precise positioning. You’ll find them on linear drives, heavy positioning, lifting gear and high-load conveyors. Search by the code on the old belt, such as AT10-1010-25, and use the filters to narrow it down by length or width.

Finding the right AT10 belt

Reading the codeAT10-1010-25 is a AT10 belt with a 1010mm length and a 25mm width. Some makers write it as 25 AT10/1010 (width, profile, length), which means the same belt.

Counting teethLength divided by 10mm gives the tooth count, so a 1010mm AT10 belt has 101 teeth. Check whether you need an endless belt or open length for clamping.

AT10 or T10?Both are 10mm pitch, but AT10 teeth are bigger and need AT pulleys. If the drive has T10 pulleys, stick with a T10 belt.

Tip: Many PU belts are supplied as open length or cut to width, and belts cut to width or length to order can’t be returned unless faulty, so check the pitch, length and width before ordering.
