Components of our new INSPIRE SERIES SBR® roller chains are coated with a film of stainless steel achieved through a proprietary blast treatment. The film works with the high quality pre-lubricant to protect the chain from corrosive attack and extend life. The blast also gives the chain an enhanced silver color appearance.
Compressive stress has long been known to improve fatigue strength. Sources of compression in existing chain products include shot peening, high interference fits between pins, bushings and side plates, and the carburized zone found on pins and bushings. Our unique patent pending "Hi-Energy Mechanical Process" imparts substantial compressive stresses to the chain components (see chart right) resulting in a 45%-50% increase in fatigue strength. Horsepower ratings as well as the rated working loads are the highest in the world.
A residual, but important benefit of Hitachi's new "Hi-Energy Mechanical Process" is that an ultra-high hardness shell is developed on the surface of carburized pins and bushings. This effectively gives these wearing components three layers of hardness protection: 1.Ultra-high hardness shell (Black Zone-See Below). 2. High hardness carburized case (Blue Zone-See Below). 3. Core Hardness (Orange Zone-See Below).
In 1987, Hitachi introduced the first premium line of solid bushing/solid roller (SBR) industrial chain products to the North American marketplace. Technologically advanced manufacturing and part finishing techniques allow this series to competitively replace traditional curled components and extend chain life. This idea gained in popularity during the 1990s.
In 1997 Hitachi added a unique coating to pins and bushings. The coating assisted lubrication and protected against corrosion. A 5% to 10% increase in wear life was achieved.
New innovations in manufacturing technologies and part processing have led to the development of INSPIRE SERIESTM SBR chains.
A unique Hi-Energy Mechanical Process is performed on all of the chain's components and has yielded surprising benefits in both fatigue strength and wear performance of this remarkable series. INSPIRE SERIESTM SBR chains possess the highest working load and horsepower capacity ratings in the world.
Today, Hitachi continues to invest heavily in developing advanced product solutions for industry. Our innovations in the area of chain strength, wear performance, corrosion protection and maintenance free operation are solving problems, and providing value to our customers and partners.
Whether for power transmission or conveying, in the food and beverage, packaging, forest product, mining, pharmaceutical, automotive, or high-speed printing industries, count on Hitachi to provide the ultimate in performance and value in industrial chain products... and the next...
