The Optibelt ZR H 420 is a timing belt with an H profile and a length of 1066.8 mm. It is used in synchronous drive systems where exact timing between the pulley and the driven component is required. Confirm fit by matching the profile and length to your existing belt.

Timing belts like this are common on industrial equipment such as compressors, pumps, and conveyors, where the belt must maintain a fixed relationship between the driving and driven pulleys. The H profile indicates the tooth shape, and the 1066.8 mm length is the pitch length. Before ordering, check that your drive uses an H profile pulley and that the required belt length matches 1066.8 mm.

To confirm the right belt, read the marking on the back of the old belt. It should show the profile and length, for example H 420 or 1066.8 mm. If the marking is worn, measure the pitch length with a belt gauge or compare the old belt to the dimensions given here. Also inspect the pulleys for wear and make sure the belt is seated correctly in the grooves.

When requesting a quote, send the part number H 420 and the quantity you need. If you are unsure whether this is the correct belt for your drive, include a photo of the old belt marking and the pulley profile. Our team can help confirm the belt or suggest an equivalent based on the information you provide.
