Browning 40P20 Chain Sprocket With AP Bushing

Browning 40P20 chain sprocket is a steel roller-chain sprocket for 40‑chain drives with 20 teeth, designed to accept a Browning P1 split-taper bushing (often described in listings as an AP bushing). The “40” denotes the 40-chain size and “20” the number of teeth, placing this part squarely in Browning’s 40‑chain family. This sprocket mounts on a drive shaft via the P1 split-taper bushing to provide secure, removable attachment and precise alignment in power-transmission or conveying equipment. Installation requires selecting the correct Browning bushing to match bore size and shaft diameter, ensuring square mounting and stable operation. The tooth profile is engineered for compatibility with standard Browning 40‑chain geometry, delivering reliable engagement with chain pins and consistent wear behavior, and it is typically paired with other Browning 40‑chain components to complete a serviceable drive train.
