When it comes to selecting the right grease for your application, there are several factors to consider. Here are some guidelines to help you make an informed decision:
Exposure to Water and Moisture
If your application is exposed to water and moisture, it’s essential to choose water-resistant grease to prevent it from washing off or absorbing moisture. Otherwise, the grease can drop out of the lubrication point, leading to ineffective lubrication.
Operating Temperature
Consider the operating temperature of your application. If it operates above 80°C, select heat-resistant grease to prevent it from seeping out of the lubrication point.
Contact with Both Water and Heat
For applications in contact with both water and heat, multipurpose or complex grease can be a good option. They are less expensive than water-resistant grease but still offer adequate protection against heat and water.
Strong Pressure
If your application experiences strong pressure, choose a grease mixed with impact-resistant additives (EP Additives) to ensure it can handle the pressure.
General Environment
If your application is exposed to dust, dirt, or very high temperatures, you may need to grease it more frequently.
Selection of Grease Numbers and Application Method
The type of grease and application method will depend on the specific lubrication points. For centralized systems that use a pump, use a soft grease like No. 0 or No. 1. If compressing by hand or with a press gun, use No. 2 or No. 3 or harder. If labeling or painting by hand, softness is not crucial. For gearboxes that use grease lubrication, soft grease like No. 0 or No. 1 is the best option.
