Surface treated drive chain APP Series
- Protects pins from pitting corrosion that occurs outdoors and on the shore.
- The surface treatment chain which uses a special surface coating on the pin that does not lower its strength for protection against pitting corrosion, which leads to fatigue breakage.
- Outstanding performance in atmospheres where corrosion is easily accelerated, such as outdoors and coastal areas.
Features
-
・Outstanding protection in an atmosphere where pitting corrosion is likely to occur
Uses a special surface coating on the pin that does not lower its strength, making it perfect for use along coasts, rivers, and other outdoor applications, and where regular lubrication is difficult.
-
・Same strength as RS Roller Chain
APP Series chain features the same tensile strength and allowable load as RS Roller Chain, with no reduction in strength.
-
・Environmentally friendly chromium-free
The special pin surface treatment uses no harmful hexavalent chromium.
When selecting sprocket specifications
It is necessary to select a sprocket specification that corresponds to the customer's operating environment and the chain specification used.
Dedicated sprockets are required for surface treated Drive chain APP Series.
Please consult us for details.
Galvanic corrosion may occur when this chain is used with stainless steel sprockets, promoting premature roller wear.
