Ball bearings for all uses
Buying new or replacing your industrial metalworking equipment doesn't have to be a complicated process. However, ensuring you have the right type and size of a ball bearing is very important. There are various types of ball bearing, each with their own strengths and available in a number of different sizes.
Replacing old ball bearings and measuring size
If you are replacing an old ball bearing, you should be able to find the size by checking the engraving on the side. This isn't always possible, however, as they get worn off over time. In this case, you will need to measure your ball bearing to determine the exact size for the new one.
Precision is key. Use a vernier calliper for a simple, accurate measurement of your old ball bearing. If you don't have one, then a ruler can suffice, you just need to be accurate. You'll need to determine the ball bearing width, its diameter on the inside, and its diameter on the outside.
Choosing the right ball bearing
You'll then have to choose the right type of ball bearing. The three main kinds of bearing are roller bearings, ball bearings and needle bearings.
There are subcategories in all of these, depending on what the bearing is for, so you will need to identify which type of ball bearings will work for you. The most common types you will find will be the angular contact, axial and deep groove bearings.
The features you can expect from a quality bearing include high speed and heat resistance, ensuring you don't have any problems with your ball bearings down the line. Most ball bearings are made from chrome steel, however, stainless steel bearings can be less corrosive and consequentially, will need replacing less often. "Commercial grade" bearings are made from a carbon allow steel, which is cheaper to manufacture but not corrosive resistant.
