The 2B two-groove B-section cast iron V-belt sheave is a precision-machined, statically balanced pulley built for higher-load, dual-belt power transmission on air compressors, blowers, fans, pumps and industrial machinery. It runs two matched B (also 5L) V-belts and uses the popular SK-type tapered QD bushing for a secure, concentric grip on the shaft. The bushing is sold separately, letting you match the exact bore you need to your shaft or motor frame.
