There are several important factors to consider when choosing grease for bearings. Modern frequency converting techniques can reduce the life of grease for bearings. High-frequency variable speed motors, for example, have increased speeds and operating hours, reducing the life of bearing grease. The higher speed capability of an electric motor also exposes bearing grease to greater centrifugal forces, reducing its ability to lubricate bearing contact surfaces. This can result in premature aging of the bearing grease.
The Ultimate Guide To Choosing Grease For Bearings
While there are many options for grease, most published compatibility charts focus on the thickener. The calcium sulfonate-based grease is moderately compatible with other brands. Polyurea, clay, and aluminum complex greases are less compatible. The right grease for bearings requires careful consideration of the entire catalog of elements and measurements. The right choice can prevent costly bearing cleaning and extend the life of the bearing. However, it may not be suitable for every type of bearing.
The types of grease for bearings include synthetic, mineral, and petroleum-based oils. These types of lubricants are designed to be resistant to high temperatures, while those made from plant-based oils can be used in various applications. Silicon lubricants, on the other hand, are water-resistant and safe for most plastics. However, they are not recommended for high-speed operation. Regardless of the type of grease for bearings you select, it’s important to use the right kind of grease for your specific needs.
