Browning 1122654 Min Plain Bore Sprocket 11T 5/8in

Product Description

The BROWNING 1122654 is a minimum plain bore sprocket designed for roller chain drive systems in industrial and commercial mechanical applications. Built from steel, this sprocket features 11 teeth and accepts chain with a 5/8 inch pitch (Chain Trade Size 50). The plain bore design allows the installer to finish-bore and key the sprocket to the required shaft diameter within the specified bore range. The outside diameter measures 2.5 inches and the hub diameter is 1.75 inches. Licensed millwrights, maintenance technicians, and mechanical contractors typically install this component on conveyor, drive, or power transmission assemblies.

This sprocket suits Chain Trade Size 50 roller chain systems found in light-to-medium duty industrial drives, conveyor systems, pump drives, and similar power transmission equipment. The minimum plain bore configuration is intended for shops or installers who will machine the bore to a custom fit within the allowable bore range of 5/8 inch minimum to 1 inch maximum. The Bushing Series B designation indicates compatibility with standard B-series bushing and bore finishing practices.
