This Optibelt Alpha Flex timing belt is identified by the code 16 AT10 / 4200 AFX. It uses the AT10 profile with a 10 mm pitch and a 4200 mm length. It is a synchronous belt for drives that need precise, positive engagement rather than friction.
Timing belts of this type are common on industrial drives where shaft synchronization matters: conveying, positioning, and other equipment where the belt teeth mesh with matching pulleys. The AT10 profile and 4200 mm length define the fit, so confirm both against the old belt or the drive documentation before ordering.
The simplest way to confirm fit is to read the marking on the back of the belt you are replacing and match the profile and length. If the marking is worn or unreadable, measure the belt and check the pulley groove profile. Send the part number, the profile and the length to our team and we will help confirm the right belt or suggest an equivalent.
