There are a huge number of variables you need to weigh up when selecting the right types of bearings for your project. There’s no doubt things can get confusing, particularly if your project is non-standard.
That’s why we’ve written this bearing selection guide. With clear sections dedicated to environment, size, speed, load, tolerances and lubrication, we will help you to ask the right questions and look closely at the application and the environment your bearings will be used in.
Whether it’s a high-speed application, or for a product with an axial load, this guide has you covered.
Bearing selection procedure
Getting the right bearings and lubrication combination ensures a long service life for the bearings and rolling elements of machines. The selection procedure is much more than just checking the load rating supplied by the manufacturer, although this is a good starting point!
You need to analyse your application closely, and really consider the many different design factors that make up ball bearings. From varying materials, to high-temperature lubrication, there is a lot to think about.
For example, when selecting bearings for high moisture environments like marine applications, full ceramic bearings are often the go-to option, especially for fully submersed applications. 316 grade stainless steel bearings are also commonly used in moving water or above the waterline. Also known as marine grade stainless steel, this material is an austenitic stainless steel, meaning it has very good corrosion resistance.
Whatever operating environment you’re working with, we’ll help you weigh up your best options in this guide.
Don’t push your bearings beyond their limits
When selecting a bearing, it is sometimes tempting to push them beyond their speed or load ratings, but as this guide explains, that’s a bad idea.
Of course, there are ways to boost a bearing’s capabilities, such as using a bigger bearing for increased loads. Similarly, we believe many design challenges can be overcome with strategic bearing considerations. If you have a bearing conundrum on your mind, get in touch today. We can discuss rotational speed, limiting speed and combined loads to name just a few technical factors.
