Great bearings, great price!

I am rebuilding an old Delta/Rockwell drill press and was having trouble finding the correct replacement bearings at a reasonable price from my usual go-to online dealers; from those that even had them available. Shipping times where reasonable. Competitively priced at time of purchase. Stock status was available, had to use contact link to make sure they were available to ship. Would be very nice if real-time in-stock status could be available while hunting down need parts, but in the long run it's not that big of deal. The stock status email back following the inquire was quick with a quoted price and purchase link.

Motor bearings

Of all the bearings I have purchased in the last 45 years, these look to be top quality.

How do I choose the right type of bearing for my application?

Start with the load and how it’s applied. You need to know if you’re dealing with radial loads, axial loads, or a mix of both. Then look at speed, operating environment, and space constraints. For example, ball bearings are great for high speed and lighter loads, while roller bearings handle heavier loads but usually at lower speeds. If there’s contamination, moisture, or heat involved, you may need sealed bearings or specific materials. In most cases, the right choice comes down to matching load type, speed, and environment to the bearing design.

What is the difference between deep groove and angular contact ball bearings?

Deep groove ball bearings are the most common type. They’re designed to handle mainly radial loads, but they can also take some axial load in both directions. They’re simple, versatile, and used in everything from motors to conveyors. Angular contact ball bearings are built for combined loads, especially where there’s significant axial force in one direction. They’re often used in pairs and are common in higher precision or higher load applications like pumps and gearboxes. If your load is mostly radial, go deep groove. If axial load matters more, angular contact is usually the better choice.
