Description
Overview:
The Engine Chain Sprocket 1/2" Pitch 21 Tooth with 1 1/2" Bore and Keyway is a genuine Benford drive component designed for reliable power transmission on construction and garden machinery. It is a robust steel sprocket with 21 teeth, set to a 1/2 inch pitch (12.7 mm) for consistent chain engagement and smooth running. The 1 1/2 inch bore (38.1 mm) includes a machined keyway for a secure, positive drive on keyed shafts, helping maintain alignment under load. Suitable for use across Benford plant and compatible with selected Terex and Mecalac machines where the same specifications are required, it is ideal for maintaining or refurbishing older equipment. Supplied as unused old stock, it may show light tarnish or storage marks that do not affect performance.
