JMG series valve gearboxes with a reduction unit begin with the JMG88 S32 model and go all the way up to the JMG1380-PG540. The highest output torque of these gearboxes is 150000 NM, which allows them to significantly satisfy the majority of the working requirements of any industry. The gears and worms of the JMG series valve gearbox are all created independently by us. They have a high processing precision and tiny machining tolerances, which enables a better engagement between the various accessories. When utilizing our products, customers have the ability to intuitively feel that the handwheel does not jam while that device is being operated.
In addition to this, we use lubricating oil that is low in temperature, which increases the product's service life by a significant amount. Customers are able to save money because they do not have to add any additional lubricating oil while they are using the product. As a matter of course, we are able to provide oil nozzles at no additional cost to our customers.
Torque range: 260N.m to 150000Nm
Capable of guaranteeing a gear contact ratio that is greater than that of a 0.1mm disparity in the process.
Use a ASTM5140 material for the shaft, which has a significantly higher strength.
The surface has been subjected to carbonization treatment.
Unit featuring high efficiency reduction
90° rotation (±5°)
Self-locking device that is stable
Temp range: -45℃ to 180℃, providing a broader temperature range for use
Weatherproof level: IP67 (optional: IP68)
