Description
JZQ(ZQ) gearbox belongs to two-stage cylindrical gear transmission. It is widely used in crane transportation, machinery, mining machinery and general chemical industry. The internal gears adopts material of high-strength low carbon alloy steel with carburizing and quenching, its hardness reaches HRC 58-62. with high accuracy and good contact. JZQ gearbox has the advantages of small volume, light weight, long service life, high loading capacity, stable operation, low noise, easy to disassemble and install.
Our company has been certified by ISO9001 quality management system. Each cylindrial gearbox will go through strict inspection before leaving our factory.
