The GB range of Chains, Sprockets, Couplings and Pulleys has evolved from 20 years expertise in the importation and sale of products locally in Australia. The GB range is proudly imported from China from a group of individually selected manufacturers producing a quality of product that exceeds local expectation and standards. China, like other nations have before them, is fast developing into a quality manufacture of products for the industrial power transmission industry. Amongst the many manufacturers are a small group that continues to strive to better the finished product and reach their goal of equaling the quality and reputation of today's market leaders.

The best of these products will carry the GB brand and are backed by the local importer's vast product experience and expertise. The GB product will be supported by detailed technical and promotional material and like the other leading brands will be warranted to be free from faulty workmanship and materials for a 12 month period. Products now carrying the GB brand are procured from factories using modern, state of the art machines and manufacturing processes. They have all been visited by GB Power and will continue to be on an ongoing basis to ensure their level of quality continues to grow over time. All have quality systems in place and all conform to the standards required by international markets.

TENSIONER & IDLER SPROCKETS

GB adds Chain Tensioner to compliment the range. After being asked by many of our customers, GB Power Transmission is proud to announce that a full range of chain tensioners is now available from stock. The GB branded rubber block tensioners are a proven and effective way for tensioning chain and belt drives in most applications. Properly tensioned drive assemblies ensures maximum service life and reduced maintenance costs.

The new GB Tensioners interchange with leading brands and are virtually maintenance free in most applications. They can be mounted in any position to provide tension to drive in almost any application. They mount via a single bolt onto the body of the main tensioner arm. The new series GB tensioners are a high quality replacement and like all GB Power products are extremely competitive.
