This Optibelt Alpha Torque timing belt is identified by the code 12 AT10 / 880. It uses the AT10 profile with a 10 mm pitch and an 880 mm length. Synchronous belts of this type are used on drives where the belt teeth mesh with matching pulleys to keep the driven shaft in step with the driver.

The AT10 profile is a metric synchronous profile, so this belt is normally found on industrial drives rather than on front-end accessory drives. Typical uses include positioning and indexing axes, conveyors, packaging equipment, and other machines where the belt must transmit motion without slip. The 880 mm length and 10 mm pitch tell you the belt runs on AT10 pulleys and that the center distance and pulley sizes must match that length.

To confirm fit, read the marking on the back of the old belt and compare it with 12 AT10 / 880. Check the profile against the pulley grooves: an AT10 belt must run on AT10 pulleys. Measure the width and tooth count if the marking is worn, and count the teeth on the old belt to verify. If the old belt is damaged or the marking is unreadable, send photos of the belt and the pulleys.

When you request a quote, send the part number 12 AT10 / 880 along with the machine make and model if known. If you are replacing more than one belt on the same drive, include all the codes so we can quote them together. We carry Optibelt belts and can help confirm the right belt or suggest an equivalent.
