FATIGUE STRENGTH

Development History-SBR®

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 SERIES™ SBR® chains.

Stainless Steel Blast Treatment

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 coor appearance.

COMPRESSIVE RESIDUAL STRESS MEASUREMENTS

Compressive stress measurements. The deeper trough of the INSPIRE SERIES™ SBR® pin means that the part has more compressive residual stress and is therefore more resistant to fatigue failure. Link plates, rollers and bushings undergo the same treatment with similar results.

Compressive Residual Stress Zones

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.

Triple Zone Hardness Wear Protection

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).

MICRO HARDNESS MEASUREMENTS

Micro hardness measurements of the pins and bushings reveal an ultrahard shell which fights chain elongation far beer than can be achieved with conventional carburized parts.
