The Gates Micro-V PK 963 is a Poly-V (multi-rib) belt with a PK profile and a 963 mm length. For a maintenance or purchasing professional, those two values are what identify the belt before any other check. Use them to match a drive or to compare against the marking on the belt you are replacing.

The PK profile tells you this is a multi-rib belt with a specific rib pitch, not a classic V-belt or a timing belt. The 963 mm length is the datum to match when the drive is being rebuilt or a spare is being ordered. Both values appear in the part number and should be read together, because a belt with the same profile but a different length will not fit the same layout.

When you request a quote, send the part number PK 963 and, if you have it, the marking on the back of the old belt. The MR team can confirm the belt against the profile and length and reply by WhatsApp or email. If the drive has more than one belt, note that on the request so the set can be reviewed together.

For drive inspection, check the ribs for cracks, missing sections or glazing, and check the pulleys for wear or debris that can shorten belt life. A belt that runs hot or slips may point to alignment or tension rather than the belt itself. Replacing a belt before it fails is the usual practice on drives that cannot be stopped without cost.
