{"product_id":"2bk-double-groove-b-section-cast-iron-pulley-h-bushing","title":"2BK Double-Groove B-Section Cast Iron V-Belt Pulley — H-Bushing Type (Bushing Sold Separately)","description":"\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch3\u003eKey specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDouble (2) groove, B-section — also runs 4L, A, and 5L (B\/BX) V-belts\u003c\/li\u003e\n\u003cli\u003eFine-grained cast iron, statically balanced for smooth, vibration-free running\u003c\/li\u003e\n\u003cli\u003eOutside diameters from 3.35\" (2BK32H) up to 12.75\" (2BK130H)\u003c\/li\u003e\n\u003cli\u003eH-bushing type — requires a separate \"H\" bushing (sold separately)\u003c\/li\u003e\n\u003cli\u003eTwo grooves for higher drive capacity and load sharing across belts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eChoosing the right bushing\u003c\/h3\u003e\n\u003cp\u003eEach pulley needs a matching \"H\" bushing bored to your shaft diameter.
