Product Description
JMG series valve worm gearbox from ZHangZhoug CHINAMFG Auto-tech Co.,Ltd has the advantage of high transmission efficiency and it has the stable self-locking design. Users can adjust the speed ratio based on their real using condition. Also, JMG valve worm gearbox can achieve 90 degree rotation, which can be widely used in ball valve, butterfly valve and other quarter turn valves. JMG series adopts 45cr material shaft, which has the higher level strength. Also, the surface has undergone carbonization treatment, greatly improve the whole strength, and guarantee its ability to work in the hard using condition. CHINAMFG provides wider range of using temprature from -45°C until 180°C. JMG worm gearbox has the superior gear contact ratio, CHINAMFG can guarantee only have 0.1mm process difference.By using our gearbox, it can help to achieve more precise, more confortable valve control.

Can I Use Synthetic Oil in My Gearbox?
Yes, you can use synthetic oil in your gearbox, and in many cases, it can offer several advantages over conventional mineral-based oils:
- Improved Temperature Stability: Synthetic oils typically have a higher resistance to thermal breakdown, making them suitable for gearboxes that operate at high temperatures.
- Enhanced Lubrication: Synthetic oils often have superior lubrication properties, providing better protection against friction, wear, and component damage.
- Extended Oil Change Intervals: Synthetic oils can often withstand longer operating periods without losing their effectiveness, reducing the frequency of oil changes and maintenance.
- Reduced Viscosity Changes: Synthetic oils are less prone to viscosity changes at different temperatures, ensuring consistent lubrication performance in varying conditions.
- Lower Friction and Energy Loss: The smoother molecular structure of synthetic oils can lead to reduced internal friction, potentially improving gearbox efficiency and performance.
- Cold Weather Performance: Synthetic oils generally flow better at low temperatures, making them suitable for gearboxes operating in cold climates.
- Protection Against Oxidation: Synthetic oils often have better resistance to oxidation, helping to prevent the formation of sludge and deposits that can impact gearbox performance.
However, before switching to synthetic oil, it’s important to consider the manufacturer’s recommendations and specifications for your specific gearbox model. Some gearboxes may have specific requirements or restrictions on the type of lubricant to use. If the manufacturer approves the use of synthetic oil, it can be a beneficial choice, but if not, sticking to the recommended oil type is crucial to ensure proper gearbox function and warranty coverage.
