Sprockets

Patented sprocket

Nordic Quick Systems’ patented solution may be applied to all types and sizes of sprocket, for example conveyor sprockets, roller sprockets (in single and multiple rows), driving drums and smooth tail wheels. The concept is also applied to cogwheels.

The sprocket is a combination of a body and several wear parts. The wear parts the easily be rotated or replaced while the chain and sprocket still are mounted on the conveyor, which generates decreased maintenance costs, minimized risks for the personnel, increased production efficiency and reduced environmental footprint.

Nordic Quick Systems’ sprockets are available in many different types of material. The wheel body is usually made of standard structural steel and the wear parts of through-hardened steel. However, the wear parts may also be made of technical plastic.

All our sprockets are supplied with wear indicators. One wear part for each sprocket is provided with markings on its sides. When the wear reaches these markings, the wear parts should be rotated or replaced to avoid the risk of breakdown. (The wear indicator is not provided in the USA, Canada or Japan.)

Product specification

    Type of sprockets

    Conveyor sprockets, roller sprockets, drive drums, flat tail sprockets, etc. The sprocket body is supplied split as standard, but solid bodies can also be produced. The sprockets may be equipped with a bearing-mounted hub or tensioning element, upon request.

    Size

    Nordic Quick Systems manufactures sprockets in all sizes, irrespective of diameter, size and hub.

    Type of chain

    We can supply sprockets for most types of chain.

    Materials

    The sprocket body is mostly produced from standard structural steel, S355J. The wear parts are produced primarily from wear plate with a nominal hardness of 400-500 HBW, or alternatively from engineering plastic. All choices of material are adapted to customer requirements.

    Accessories

    The wear parts and sprocket halves are secured with Nord-Lock washers (except plastic wear parts) and 12.9 bolts.

    Contour

    The contour of the wear parts holds a high degree of precision to ensure a low-impact chain drive.

    Miscellaneous

    All split sprocket bodies are equipped with supporting bosses between the sprocket halves, ensuring an optimum split. To eliminate the risk of abrasion, the sprocket body is always slightly narrower than its wear parts.
