Timken 22318EMW33C3 is a spherical roller bearing with a 90 mm straight bore and C3 radial internal clearance. It features a brass (EM) cage for shock and high-temperature applications up to 400°F, with a W33 lubrication groove and three holes in the outer ring. This self-aligning bearing has a dynamic load rating of 136,000 lbf and is suitable for industrial gearboxes, crushers, and heavy machinery where misalignment is present.

Spherical bearings are designed to manage high radial loads even when misalignment, poor lubrication, contamination, extreme speeds or critical application stresses are present.

Read moreHow 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.
