Individual V-belts do not require exact groove spacing to properly operate. Therefore, both A and B-section single V-belts can be used with Gates Multi-Duty combination sheaves.
However, PowerBand® joined V-belts require very specific groove spacing for proper fit and operation. Gates Multi-Duty® combination sheaves use B-section groove spacing, making only B-section PowerBand V-belts compatible.
Sheaves that may be used with A-section PowerBand V-belts are available through Gates Made-to-Order Metals (www.gates.com/mtometals/).
