Description
OPTIBELT 5M 1690 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 5M 1690 and any equivalents.
This Optibelt Omega timing belt is identified by its HTD 5M profile and 1690 mm length. The 5 mm pitch defines the tooth spacing that must match your drive sprockets. Use these three values to confirm the belt your application requires.
The HTD 5M profile is a synchronous belt type with a 5 mm pitch. The 1690 mm length is the belt's datum length. Both figures appear in the belt marking and in your equipment documentation. A timing belt must match the sprocket groove profile and the center distance the drive was built for.
When you request a quote, send the part number 5M 1690 and confirm the profile and length from the old belt. If the marking is worn, photograph the back of the belt and the sprockets. Our team can help confirm the correct Optibelt Omega timing belt or suggest an equivalent.
