Product Description

Heavy Duty Engineering Chains WG781 WG103 WG103H WG140 WB10389 WB9525 WB7900 WB7938 Offset-sindbar Roller Chains

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 against 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.
