FAQ

The 'EA' indicates a high-capacity design with a pressed steel cage. The 'E4' denotes a lubrication groove and lubrication holes in the outer ring, which is a standard feature to facilitate effective re-lubrication.

Spherical roller bearings are primarily designed for high loads at moderate speeds. While the steel cage offers good performance, for very high-speed applications, you should consult the manufacturer's documentation for limiting speeds and lubrication requirements.

The appropriate lubrication (grease or oil) depends heavily on the specific operating conditions, including speed, load, and temperature. It is crucial to use a high-quality grease with an appropriate viscosity and EP (Extreme Pressure) additives for most industrial applications.
