Description
OPTIBELT T5 390 belongs to timing belt, part of our Power transmission range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for T5 390 and any equivalents.
The Optibelt Alpha Power T5 390 is a timing belt with a T5 profile, a 390 mm length, and a 5 mm pitch. When you read the marking on the back of an old belt, these are the values to match. We carry this belt and quote it by part number.
Start with the marking on the back of the belt you are replacing. It should show the profile and the length. For this belt, that is T5 and 390 mm. The pitch is 5 mm. If the old marking is worn or unreadable, measure the belt and count the teeth to confirm the profile and length before you request a quote.
This is a synchronous belt, so the teeth drive the pulley without slipping. A worn belt can show cracked teeth, exposed cord, or a glazed back. Check the pulleys for worn grooves or debris at the same time. If the drive uses more than one belt, replace them as a set so the load stays even.
Send the part number T5 390 by WhatsApp or email to request a quote. If you are unsure about the profile or length, include a photo of the old belt marking and the pulley. Our team can confirm the right belt or suggest an equivalent.
