Browning BK120X1 is a finished-bore, single-groove V-belt pulley from the BK Series designed for 4L/A and 5L/B cross-section belts. It measures 11.75 inches (11-3/4") in outside diameter with a 1-inch bore and 18 teeth, forming a 1-groove configuration for compact power transfer. Cast-iron construction provides rigidity and durability for industrial belt drives, making it a common choice when a 1" bore, 11.75" OD BK120X1 pulley is required.
