Heavy Duty Offset Sidebar Roller Chain
The heavy duty offset sidebar roller chain is designed for drive and traction purposes, and is commonly
used on mining equipment, grain processing equipment, as well as equipment sets in steel mills. It is
processed with high strength, impact resistance, and wearing resistance, so as to ensure safety in heavy
duty applications.
Design and Processing Advantages
1. Made of medium carbon steel, the offset sidebar roller chain undergoes processing steps like heating,
bending, as well as cold pressing after annealing.
2. The pin hole is created by impact extrusion, which increases the inner surface smoothness for the hole.
Thus, the matching area between the sidebar and the pin is increased, and the pins offer higher protection
again EPT heavy loads.
3. The integral heat treatment for the chain plates and rollers ensures high tensile strength. The pins
additionally undergo high-frequency induction heating for the surface after integral heat treatment, ensuring
high strength, high surface hardness, and wearing resistance as well. The surface carburizing treatment for
the bushings or sleeves guarantees high tensile strength, superb surface hardness, and improved impact
resistance. These make sure the heavy duty transmission chain has extended service life.
