New SBR and Neo-SBR roller chains offer up to a 30% increase in Maximum Allocable Load (M.A.L.) compared to Hitachi’s previous range.
By using a high energy mechanical process, Hitachi have improved fatigue strength in their new range of roller chains by improving compressive residual stress zones.
Heat treatment has also been improved with the introduction of triple zone hardness wear protection for pin and bushing.
Hitachi has achieved maximum wear capacity of the heart of the new roller chains by better balancing the heat treatment to exact depths.
Components are treated with a unique stainless steel blast to address issues of corrosion. This film works with a high quality pre-lubrication to protect the roller chains from corrosive attach and extend life.
