Rolling Bearing-Four Row Cylindrical Roller Bearing FC3248124

Rolling bearing-four row of cylindrical rollers are in contact with the bearing. Load capacity, mainly bear radial load.

The four row of cylindrical roller bearing have a conical inner ring and the outer ring, and the conical roller is arranged between the two. All the projection lines on the surface of the cone are gathered at the same point of the bearings axis. This design makes the conical roller bearing is particularly suitable for to withstand the load (radial and axial) load. Most of the axial load capacity of the bearing is determined by the contact angle α; the larger the α angle, the higher the axial load capacity. The angle size is represented by the calculation coefficient E; the larger the E value, the greater the contact angle, the greater the applicability of the bearing receiving axial load.
Rolling bearing-four row cylindrical roller bearings are usually separated, that is, the cone inner ring component consisting of the inner ring of the roller and the inner ring of the holding frame can be installed separately from the outer ring (outer ring).
Rolling bearing-four row of cylindrical roller bearing are widely used in industries such as cars, rolling machines, mines, metallurgy, plastic machinery and other industries

It is usually installed on the neck of the roll, which is particularly suitable for rolling machine applications with high rolling speed. The low cross -section of these bearing allows the diameter of the roller neck with a relatively large roller neck of the roller diameter. Because it can be loaded with a lot of rollers, its radial load capacity is very high. Four columns of cylindrical roller bearings can only withstand radial loads. Therefore, these bearing with deep groove ball bearings or angle contact ball bearings, or cone roller bearings with radial structure or stop structure, will be installed together, and the latter bears the axial load. The four -column cylindrical roller bearing is a separate structure, that is, the bearing ring with the overall gear edge, the roller and the kernel component can be installed separately with the separation of the bearing ring.
