Dear customers,

  Paralloid Gear Co., Ltd. possesses design, analysis, manufacturing and three-dimensional measurement technology for teeth of various gear such as helical gear, bevel gear, hypoid gear, face gear, worm gear, cycloid gear, harmonic drive, scroll compressor, screw compressor, etc. Also, it is possible to design and process simulation of tools for rolling, milling, hobbing, skiving, etc. for the manufacture of various gears. Based on those technology, we are trying to provide the best solution by responding actively to any needs of customers.

  In particular, we have the world-class technology in worm gears, which enables production of cylindrical worm gear, roller gear cam and hourglass worm gear, and are also developing injection molds / sintering molds for double enveloping worm wheel, and rolling die / hobbing tool for hourglass worm. In addition, we invented and developed the Paralloid Gear, which is a hourglass shaped gear that enables parallel axes power transmission, beyond the worm gearing that transmits the power between intersecting axes. The new invented gear can surpasses and replace the existing helical gears.

  All of our employees are constantly striving to maintain and develop the world's best technology. As part of this effort, we have developed the screw rotor, a key part of the single screw compressor, and continue to develop the world's best products in this field.

  In the Fourth Industrial Revolution that has already begun, we hope that our efforts will help a little to enhance the competitiveness of customers’ products which use our gears, and we will do our best to realize it.
All employees of Paralloid Gear Co., Ltd.
