It features an outside diameter of 7.28 inches and accepts bore sizes from 5\/8 inch up to 2-1\/4 inches through a B-style QD bushing, which is sold separately. The sheave is cast iron construction and is compatible with 5V, A, and B cross-section V-belts. It is installed by licensed HVAC technicians and mechanical contractors on blower assemblies, fan drives, and general power transmission setups where multi-belt torque loads require a robust, field-adjustable mount.\u003c\/p\u003e\n\u003cp\u003eThis sheave fits standard belt-driven blower and fan systems common in commercial and residential HVAC equipment, as well as light industrial machinery. The three-groove configuration allows the drive to handle higher torque loads by distributing tension across multiple belts simultaneously. The B-style QD bushing interface makes field installation and removal straightforward without requiring specialized tooling beyond standard hand tools.
