When a timing belt needs replacing, the marking on the back of the old belt is the most reliable starting point. This page covers the Optibelt 100 AT5 / 12000 AFX from the Alpha Flex series, a timing belt with an AT5 profile, a 12000 mm length and a 5 mm pitch. Read the old marking carefully and match it to these values before you request a quote.
The Optibelt 100 AT5 / 12000 AFX is a timing belt in the Alpha Flex series. Its profile is AT5, its length is 12000 mm and its pitch is 5 mm. These three figures identify the belt on a drive. If the marking on your old belt shows the same profile and length, this is the reference to quote. If the marking is worn or unreadable, measure the drive or send a photo of the belt and the pulley arrangement so the team can help confirm the correct item.
Timing belts are often replaced as part of scheduled maintenance, and on multi-belt drives it is good practice to inspect all belts in the set at the same time. Check pulleys for wear, alignment and debris, and confirm that the replacement belt matches the original profile and length. The Optibelt 100 AT5 / 12000 AFX is supplied by MR Industrial Accessories LLC to maintenance, engineering and purchasing teams across the United States, Canada, Mexico and South America.
