NM series - Rod drive

The NM Series is Broekema’s modular alternative to the traditional N Series sprockets. Designed for applications where a standard cast iron N-type sprocket is unavailable in the required pitch or diameter, the NM Series offers flexibility without compromising performance.

Each NM sprocket consists of four components: a steel outer ring (with or without flange), a reinforced inner ring, riveted hardened drive fingers, and a bolted-on hub. This modular setup allows for easy customization and serviceability. If pitch or diameter changes are required — or in the case of wear — only the gear ring needs to be replaced, while the hub remains in place on the shaft.

The NM Series engages directly with the cams in traction belts (such as EN0900, DN0909, G0505, EN1200P, and DN1209P), ensuring precise drive and optimal grip. Modular construction eliminates the need for welding, increasing reliability and reducing production time for custom sizes.

With a design built for easy assembly, service, and customization, the NM Series is an excellent choice for high-performance belt-driven systems in harvesting and processing applications.
