The Optibelt Alpha Power T5 425 is a timing belt with a T5 profile and a 425 mm length. It is used on drives that need synchronous power transmission, where the belt teeth mesh with matching pulleys to keep the driven components in step.
To confirm fit, check the marking on the back of the belt you are replacing. The profile must be T5 and the length must be 425 mm. The pitch on this belt is 5 mm, so the pulleys on the drive must be cut for T5 profile and 5 mm pitch. If the old belt is worn or the marking is unreadable, measure the length and count the teeth, then send those details with your quote request.
This belt is a synchronous belt, also called a timing belt, and is selected by profile and length rather than by cross-section like a V-belt. The T5 profile and 425 mm length identify the size. When you request a quote, send the part number T5 425, the profile, and the length so we can confirm the correct belt for your drive.

Frequently asked questions
- How do I confirm the T5 425 is the right belt for my drive?
- Read the marking on the back of the belt you are replacing. It should show T5 and 425. The profile is T5, the length is 425 mm, and the pitch is 5 mm. If the marking is gone, measure the belt length and check the pulley profile before ordering.
- What does the T5 profile mean?
- T5 is the profile of the timing belt. It has a 5 mm pitch, which is the distance between the centers of two adjacent teeth. The pulleys on the drive must match the T5 profile and the 5 mm pitch for the belt to run correctly.
- What information should I send with a quote request?
- Send the part number T5 425, the brand Optibelt, the series Alpha Power, and the profile and length. If you are replacing a belt with a different marking, include that marking and any pulley details so we can help confirm the right timing belt.
