Description
As a trusted supplier of high-quality machinery parts, Quanzhou Zhongkai Machinery is committed to delivering superior products that meet the needs of the modern construction and mining industries.
Track roller composition description:
Wheel body: forged from 50Mn/40Mn round steel with good hardenability: The heat treatment process of quenching and tempering and medium frequency surface quenching ensures its strength and wear resistance.
Shaft: 45 # round steel material, heat treatment process of quenching and tempering + medium frequency surface quenching, surface hardnes:HRC52-60. depth of hardened layer 3-6mm, excellent comprehensive performance.
Floating oil seal: made of high chromium and high molybdenum alloy.
Hardness HRC65-72 working surface roughness 0.1uM-0.2uM
O-ring: It is produced from butylene and acrylonitrile, which are copolymerized into butylene and acrylonitrile, and has better oil resistance and high temperature resistance.
