Founded in 1993, Shandong Guomao Guotai Reducer Co., Ltd. is a large-scale reducer manufacturer in China. We own a workshop covering an area of 50,000sqm and over 600 machining tools and testing equipment. In our 4,000sqm constant temperature workshop, there are 58 sets of high-efficiency and high-precision NC gear grinding machines and an automatic gear testing center, which represent world-class level. The machine's installation and debugging precision is up to Grade 3, which ensures mass production of Grade 5-6 gears. Our annual sales income is over RMB900 million. Our products sell well all over the world. We have successfully developed various products, including B and X serial cycloidal-pin gear speed reducers, 8000 serial cycloidal-pin gear speed reducers, Z (ZDY, ZLY, ZSY, and ZFY) serial hard gear face cylindrical gear speed reducers, MBY serial side-driven reducers, D (DBY and DCY) serial hard gear face cone gear speed reducers, GR serial helical gear speed-down motors, GS serial helical gear worm gear speed-down motors, GK serial helical gear curved tooth cone gear speed-down motors, GF serial parallel axis helical gear speed-down motors, P and V serial industrial gearboxes, ZLYJ serial hard gear face speed reducers for plastic extruders, and YB serial oil cooling electric drive drums. We also design and manufacture non-standard speed reducers. In addition, we recommend RV and VF serial aluminum alloy worm gear speed reducers, WP serial involute worm gear speed reducers, JWM, SWL and WSH serial screw lifters, CW serial arc worm gear speed reducers, secondary enveloping worm gear speed reducers, and various couplers.
