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 are the dimensions and typical uses of a 6200 series ball bearing?: A standard 6200 ball bearing has: • 10 mm bore • 30 mm outer diameter • 9 mm width The 6200 series sits within the deep groove ball bearing family and is designed for light to moderate loads at relatively high speeds. You’ll typically find them in electric motors, small gearboxes, pumps, and general industrial equipment. They’re popular because they’re compact, widely available, and cost effective. Different variants exist such as sealed, shielded, or high clearance versions, depending on the application. - 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.
