Nachis new BMBU 40 degree angular contact ball bearings have a counter bored inner ring and new optimized cage for better lubricant flow, especially in vertical shaft electric motor applications. Lower rotating mass results in better energy efficiency. The raceways of both the inner and outer rings of this bearing type are made with a set contact angle. Single row angular contact ball bearings can sustain radial, axial or composite loads, however any axial load must be in one direction.
Larger contact angle type has better axial load capability. Small contact angle type has higher permissible speed capability. This bearing type is generally used in adjacent positions.
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.
