The 2BK double-groove (2-groove) B-section cast iron V-belt pulley is a precision-machined, statically balanced sheave built for higher-load, dual-belt power transmission on air compressors, electric motors, and industrial belt drives. This is an H-bushing (bushed) design: the pulley is bored to accept a separate two-piece "H" style bushing that clamps firmly onto the shaft as the bolts are tightened — a more secure and serviceable mount than a one-piece fixed-bore pulley. Running two belts spreads the load and increases drive capacity. The H bushing is sold separately, so a single pulley can be matched to a range of shaft diameters.
Key specifications
- Double (2) groove, B-section — also runs 4L, A, and 5L (B/BX) V-belts
- Fine-grained cast iron, statically balanced for smooth, vibration-free running
- Outside diameters from 3.35" (2BK32H) up to 12.75" (2BK130H)
- H-bushing type — requires a separate "H" bushing (sold separately)
- Two grooves for higher drive capacity and load sharing across belts
Choosing the right bushing
Each pulley needs a matching "H" bushing bored to your shaft diameter. Not sure which bushing size you need? Simply add your shaft diameter or motor frame to the end of the pulley part number and we'll include the correct bushing — for example, 2BK32H-145T.
Typical applications
Air compressor drives, electric motor and engine drives, fans and blowers, pumps, conveyors, and heavier-duty industrial power-transmission equipment where a two-belt drive is specified.
Available across the full 2BK range, this double-groove B-section cast iron V-belt pulley combines a durable, statically balanced casting with the flexibility of the H-bushing system for a secure, shaft-matched, higher-capacity drive.
