FAQ

The suffix provides key details. 'EA' signifies a high-capacity design with a pressed steel cage. 'E4' indicates that the outer ring has a lubrication groove and holes for effective relubrication. 'C3' denotes a radial internal clearance that is greater than standard, which is necessary for applications with high temperatures or tight fits.

Spherical roller bearings like the 22218EAE4C3 are primarily designed to handle very heavy radial loads and significant misalignment. They can also accommodate moderate axial loads in both directions, typically up to 25 percent of the radial load. For predominantly axial loads, a thrust bearing would be a more appropriate choice.

The appropriate lubrication depends on the operating speed, load, and temperature. For most industrial applications, a high-quality lithium-based grease with an EP (Extreme Pressure) additive is suitable. For high-speed or high-temperature environments, oil lubrication might be necessary, utilizing the E4 lubrication groove and holes for circulation. Always consult the machine manufacturer's manual for specific recommendations.
