You might consider banded v-belts as shown here:
McMaster-Carr is the complete source for your plant with over 595,000 products. 98% of products ordered ship from stock and deliver same or next day.

Since banded v-belts are made on the same mold at the same time, they have a much better chance of being the same size. The back binding helps distribute the load better than three individual belts.
McMaster also offers matched belt sets if your pulley will not accommodate the banded v-belts due to pulley dimensions.
From experience, if you are wearing out v-belts, you might consider why. In the big HVAC world, belts wear out due to frequent start/stop cycles. In many cases, installing a soft-start device to the motor reduces the initial full-speed torque on startup (this is evident when you hear the belts screaming for their lives every time the motor was started, and the great pile of carbon-black/rubber dust all over the immediate vicinity).
Soft starters are not cheap ... in fact they can be as much, if not more than a VFD (and YES, for some motors, you CAN get a VFD ... see this link

As a rule, link belts were (in the industries I worked) used as a temporary repair until the correct v-belts arrived (almost in time delivery has been a pain for a number of years, but that's another discussion). They were not recycled or returned to the toolbox, but tossed, as they were usually worn even after only a few hours (again, start/stop cycles tend to stress things). The good thing about link belts is you can install them without tearing equipment down (think about the spindle on a belt-driven metal lathe).
If link belts work for you ... great ... I however recommend applying the correct belt and resolving the wear issues (I completely ignored pulley misalignment, because wars have been fought over less).
Hope this helps,
