This Optibelt ZR timing belt is a synchronous belt with an XL profile and a length of 863.6 mm. It is used in drives where teeth mesh with pulleys to maintain timing between shafts. We carry this belt for maintenance, engineering and purchasing teams.

XL profile timing belts are common on light-duty drives that require synchronization rather than friction, such as small conveyors, packaging equipment, and positioning systems. The teeth engage the pulley grooves to prevent slip, so the belt must match the pulley profile exactly. If the drive runs at a fixed ratio and the pulleys are in good condition, this type of belt is a direct replacement for a worn or damaged belt of the same profile and length.

To confirm fit, check the marking on the back of the old belt and compare it with the profile and length shown here. The profile is XL and the length is 863.6 mm. Also inspect the pulleys for worn teeth, debris, or misalignment, and verify that the belt width and tooth pattern match the pulleys. If the old belt is not marked, measure the pitch length and count the teeth to cross-check against the data on this page.

When ordering, send the part number XL 340 and the brand Optibelt, along with the profile and length if you have them. Our team can confirm the belt or suggest an equivalent based on the drive details you provide. For multiple-belt drives, it is good practice to replace all belts in the set at the same time to keep loads even.
