Description
OPTIBELT 150 T10 / 4000 AFX 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 150 T10 / 4000 AFX and any equivalents.
The Optibelt 150 T10 / 4000 AFX is a timing belt in the Alpha Flex series with a T10 profile and a 4000 mm length. It is the belt to specify when you are replacing an existing drive belt and need the same profile and length.
To match it to the belt being replaced, read the marking on the back of the old belt. Confirm the profile is T10, the length is 4000 mm and the pitch is 10 mm. The 150 T10 / 4000 AFX meets those figures, so it is a direct match for the same position on the drive.
If the old marking is worn or unreadable, measure the belt and check the drive pulleys. The profile and length are the two values that decide fit. Send the part number, the profile and the length in your quote request so we can confirm the right belt or suggest an equivalent.
Inspect the pulleys, tensioner and alignment before installing the new belt. A worn tensioner or a misaligned pulley can shorten the life of any timing belt. Replace the belt as part of the drive service, not as an isolated item.
