Cylindrical roller bearing

Cylindrical roller bearings are a type of rolling bearing in which cylindrical rollers come into contact with raceways. Their core structure consists of an inner ring, an outer ring, cylindrical rollers, and a cage. The rollers make line contact with the raceways of the inner and outer rings. Compared to point-contact bearings, they offer higher rigidity, greater load-carrying capacity, and the ability to withstand larger radial loads. They are commonly used in medium- to high-speed, heavy-duty rotating applications such as motor spindles, gearboxes, internal combustion engines, cranes, mining machinery, and other medium- to high-speed, heavy-load rotating applications.
