The Optibelt 25 T5K6 / 2900 AFX is an Alpha Flex timing belt with a T5 profile, a 2900 mm length and a 5 mm pitch. Timing belts of this type are used where a drive has to keep two shafts turning in step, so the belt teeth engage the pulley grooves instead of relying on friction.
When you are confirming fit, work from the belt you are replacing. Read the marking on the back of the old belt and compare it with the part number above, then check the profile and the length against the drive. The T5 profile and 2900 mm length on this belt are the two figures that decide whether it sits correctly on the pulleys.
Inspect the drive at the same time. Look at the pulley teeth for wear or damage, check that the pulleys are aligned, and confirm the belt tension is set to the drive manufacturer's specification. A belt that has run hot, frayed at the edges or lost teeth usually points to a problem on the drive rather than the belt alone.
If you are ordering for a planned shutdown, send the part number, the quantity and the equipment it goes on. We carry Optibelt and can help confirm the right belt or suggest an equivalent where one applies.
