To extend the lifespan of a motor, one of the most important steps is to address issues within the bearing system. For the bearing to function properly, it must be well-lubricated. Grease plays a crucial role in ensuring optimal lubrication. In this article, Dalan Motor’s expert will guide you on how to select the right grease for vane pump and oil pump motors.
When choosing bearing grease, several factors should be considered:
(1) The grease should have rust protection properties and strong adhesion. It should contain a rust inhibitor that is not easily dissolved by water, allowing it to stick to metal surfaces and form a protective oil film.
(2) A proper sealing mechanism is essential to prevent contaminants and moisture from entering the bearing. This ensures that the lubricant remains clean and the bearing operates smoothly without damage.
(3) Correct maintenance practices are key to prolonging the life of the bearing. Regular inspections should include checking the cleanliness of the grease and using the right tools for maintenance tasks.
(4) Avoid mixing incompatible greases. Combining different types can cause the grease to soften, leading to loss of lubrication and potential bearing failure. If you're unsure about the original grease used, always remove the old grease before applying new lubricant.
Greases are typically classified based on temperature and operating conditions. The performance of the grease depends on its ability to maintain consistency and lubricity at various temperatures. Bearings need to be matched with grease that performs well under their specific operating conditions.
Greases are generally categorized into low, medium, and high-temperature types. Choosing the right type is essential, as improper selection can render all other protective measures ineffective. The base oil viscosity of the grease must be sufficient to provide adequate lubrication at the operating temperature, which changes with heat. As temperature increases, the base oil becomes less viscous, and as it decreases, the viscosity increases.
