Technological innovation in the field of hydraulic equipment has seen the increasing introduction of lightweight valve spool parts and a shift from the polish finishing of carburized steel, to anodizing treatment of cut aluminum parts. Miyaki’s treatment is gradually being applied to a greater variety of valves in the ongoing promotion of high quality product creation.

• Suspension / Aluminum Tubes

  Manufacturers have continued to push the boundaries of technology to bring us suspension for two-wheeled vehicles that boasts superb drivability, durability, and is both lightweight and aesthetically pleasing. High aluminum tubes - aluminum tubes treated with Kashima Coat - are attracting attention as a leading-edge material.
  
  Low friction facilitated by lubrication realizes superb drivability and durability.
  Its characteristic color and exterior gives Kashima Coat a high quality finish that is loved by many.

• Engine / Transmission

  The advancement of lean burn technology for engines – a branch of research investigating the reduction of harmful emission gases – demands pistons that can operate under extreme temperatures. It has been demonstrated that Kashima Coat treatment plays a significant role in lubricating under high temperatures. As such, there has been a steady increase in demand for use with parts such as piston ring grooves and pin holes. We are constantly working on new ways to produce more reliable, durable, and light weight moving parts able to withstand the harsh conditions of combustion engines.
  
  Rocker arms are one such example where significant weight and cost reductions were made by making the change from iron to Kashima Coat treated aluminum as its self-lubricating nature alleviates the need for bearings.
