Exploring Different Types Of AC Gear Motor Lubricants

The 3 main types of lubricants used in AC gearmotors include mineral oils, hydraulic oils, and grease. Bauer GMC, a leading distributor of gear motors, electric gear motors, gear reducers, and related accessories in Mississauga, Ontario, explores these 3 types of lubricants in this blog.

What Are The Main Types Of AC Gear Motor Lubricants?

Mineral Oils

Mineral oils are one of the most prominent lubricants used in AC gearmotors. They are a byproduct of petroleum, particularly that which occurs during the distillation process. The main goal of mineral oils is to reduce friction between the different moving components of the gear motor. These are mainly used in helical and spur gear motors. This is because mineral oils exhibit extreme pressure additive properties, helping reduce wear created by the high-pressure conditions in helical and spur motors.
 

Hydraulic Oils

Hydraulic oils serve a dual purpose in AC gear motors. Primarily, they are used to reduce heat generated during operation. Additionally, these lubricants also help reduce wear and tear between components. Hence, they contribute significantly towards reducing corrosion and improving the lifespan of the gear motor. Moreover, these types of oils also decrease shaft wear in particular.
 

Grease

Grease is fundamentally different from mineral and hydraulic oils. The main difference is their viscosity. Grease is highly viscous in nature, making it a great choice for sealing AC gear motor components. However, this viscosity also has a downside. Grease can be harder to apply uniformly to gear motor components, making its use rather limited.

Conclusion

To conclude, mineral oils, hydraulic oils, and grease are all used in AC gearmotors due to their useful properties.

FAQs:

Which type of lubricant is best for small gear motors?

Grease is best for small gear motors as it prevents leakage.
 

When is it best to use mineral or hydraulic oils for gear motors?

Oils are an excellent choice for high-speed or heavy-duty gear motors.
