Product Description
The JMG series high output torque valve gearbox with double stage from Zhejiang Jimai Auto-tech Co., Ltd. is capable of generating a high speed ratio, which allows the product to generate a high output torque with a low input torque.
The JMG88 S32 model is the starting point for the JMG series high output torque valve gearbox with double stage , and they progress to the JMG1280-DS300. These transmissions are capable of meeting the majority of the operational needs of any industry, as they have a maximum output torque of 58000 NM. All of the gears and worms in the JMG series valve gearbox are independently manufactured by us. They possess a high level of processing precision and extremely small machining tolerances, which facilitates a more effective connection between the various accessories. Customers can intuitively detect that the handwheel does not become stuck while operating our products.
Furthermore, we employ lubricating oil that is low in temperature, which significantly extends the product's service life. Customers are able to save money by eliminating the need to add any additional lubricating oil while operating the product. We offer oil nozzles to our consumers at no additional cost as a matter of course.
