Gördülcsapágy

Gördülcsapágy translates to "rolling-element bearing" in English. It is a type of bearing that reduces rotational friction and supports loads by placing rolling elements between two rings. The rolling elements are typically balls or rollers.

There are several main types of gördülcsapágy. Ball bearings use spherical rolling elements. They are good for high speeds and light to moderate loads. Roller bearings use cylindrical, tapered, spherical, or needle-shaped rolling elements. Roller bearings can generally support heavier loads than ball bearings. Common types include deep groove ball bearings, angular contact ball bearings, self-aligning ball bearings, cylindrical roller bearings, tapered roller bearings, and spherical roller bearings.

The inner and outer rings of a gördülcsapágy are called the races. The rolling elements are kept separated by a cage or retainer, which prevents them from rubbing against each other. The design of the bearing depends on the type and direction of the loads it needs to support, as well as the required speed and precision.

Gördülcsapágy are widely used in a vast array of applications, from small appliances and power tools to automotive components, industrial machinery, and aerospace equipment. Their widespread use is due to their efficiency, reliability, and ability to handle both radial and axial loads, depending on the bearing type. Proper lubrication is crucial for the longevity and performance of gördülcsapágy, as it reduces friction and wear, and helps dissipate heat.
