MA series worm speed reducer HIGH POWER ●Torque has been increased by 60% or more. ●The overhang load has been increased by 80% or more. The high quality Makiace models (MA series) were created by combining Makishinko’ years of experience in the development of s worm gear speed reducers with the latest production technology. The Makiace MA series features high power, high efficiency, reduced size and weight, good design, easy operation and high quality. It is a top-ofthe-line product for use in a variety of fields and for various purposes. ■MA100 (compared to our company’standard products) s...

EASY OPERATION ●Reduced capacity by 50% or more ●50% weight reduction, or more ●Does not require running-in. ●High loads from the start of operation are OK, and costs of running-in were eliminated. (Our comparison of capability with Type MA100) 4. GOOD DESIGN SIMPLE DESIGN ●Backlash is also acceptable for grade BS721-1. (Option) ●The output shaft ends are tapped as standard. ●A new JIS key is standard. ●The adoption of high-grade lubricants reduces the maintenance time. ●Additionally, we have created a truly low-noise and low-vibration worm. ●Slim and simple design without any projections Model...

Precaution for Handling MAKIACE Maintenance check No special running-in is necessary. However, it is recommended that, when first starting to use the product, the operating load should not exceed 80% of the rated load. Then the load can be raised Check the following items during a maintenance check. ●Lubricant changes About 50 hours of operation after first staring, replace the lubricant. Then, check the lubricant every six months. If it is dirty, replace it. ●Rise in temperature The working temperature of the product is due Be especially sure to replace the lubricant after to the sliding transmission...

Shaft Arrangement and Rotation Direction Output shaft direction Output shaft direction Input double shaft Output shaft double Input and output double shaft ●Rotation direction, normal rotation and reversal also being possible, ability is the same. ●An arrow display is the rotation direction for shaft. ●About special installation on side wall or upside-down, please contact us. ●Please decide shaft position based on output position from input position or motor. (In case of double input shaft with motor or adapter, shaft position is deicded based on output position from motor or adapter, so shaft...

Type number selection MAKIACE 3-4） When the product is used at an input rotation speed from 1800 rpm to 3000 rpm, Please pay attention to load coefficiency and thermal rating capacity. Higher temperate by higher rotation speed and continuous driving sometimes damages oil seals and oil gauges, causing leaking oil. In this case, changing specification of oil seals and oil gauges will be necessary. 3-5） control program should start and stop slowly, as much as is possible. The When selecting 1］ Load coefficient Select the load coefficient from the load coefficient table according to the operating...
