The Mitsuboshi 3PK 1120 is a Poly-V (multi-rib) belt with a PK profile and 3 ribs. Before fitting a new belt, inspect the drive and sheaves for wear, misalignment, or debris that can shorten belt life.
Check sheave grooves for wear, rust, or foreign material. Worn or damaged grooves can cause the belt to slip or seat incorrectly, even when the belt itself is in good condition. Confirm that all sheaves are clean and aligned so the 3PK 1120 runs as intended.
Verify that the replacement belt matches the original in profile and rib count. This belt has a PK profile and 3 ribs. If the old belt is stretched, glazed, or has missing ribs, replace it and address any drive issues before installing the new belt.
When requesting a quote, provide the part number 3PK 1120 and the quantity needed. If you are unsure whether this is the correct belt for your drive, send photos of the old belt and sheaves. Our team can help confirm the right belt or suggest an equivalent.
