YDTech® manufacturer of four row cylindrical roller bearings, rolling mill bearings! supplier of four row roller bearings for cylindrical rollers,spherical rollers,tapered rollers in china.

four row rolling mill bearings are a type of specialized bearings used in rolling mills to support heavy radial and axial loads and ensure the smooth operation of the rolling process. these bearings have four rows of rollers arranged in a specific pattern to distribute the load evenly across the bearing.

the four row rolling mill bearings typically consist of an inner ring, an outer ring, and four rows of cylindrical or tapered rollers. the inner and outer rings are designed with raceways to accommodate the rollers and provide support for the rotating shaft.

these bearings are commonly used in applications steel, aluminum, and copper rolling mills, where the high loads, shock loads, and high temperatures associated with the rolling process can cause significant wear and tear on conventional bearings. The design of the four-row rolling mill bearings allows them to handle these extreme conditions while maintaining the accuracy and efficiency of the rolling process.

roll mill bearings accommodate extreme radial loads and in order to carry huge draught pressure, the journal diameter of the mill roll should be broader, in the mean time, the external diameter of bearings couldn't be too bigger. Thus, roll neck bearings must improve the loading capacity of bearings according to the width of the mounting position and always adopt multi-row bearings.

cylindrical roller bearings are a type of rolling-element bearing that use cylinders (or rollers) with a slightly modified shape to reduce friction between rotating and stationary components. Unlike needle roller bearings, which have long, thin cylindrical rollers, cylindrical roller bearings have short, thick cylinders that are slightly crowned or tapered to reduce stress concentrations.

cylindrical roller bearings are designed to handle high radial loads, and in some cases, moderate axial loads as well. they are commonly used in applications such as machine tools, rolling mills, electric motors, pumps, and gearboxes.
