Four-Row Cylindrical Roller Bearings

Four-row cylindrical roller bearings for long steel rolling four-row cylindrical roller bearings are designed to withstand extreme radial loads and high-speed applications. The bearing is optimized according to the common operating conditions in the long mill to improve the performance and reduce the total cost of ownership. Different design combinations of outer ring, inner ring, Edge ring, etc. can be provided to meet different application requirements. An important feature is the detachable design, which facilitates mounting, and the various parts of the bearing can be interchanged. The radial bearing capacity is especially high, the friction is low, the service life is long, the cross section is small, and the two-way axial displacement can be separated and interchangeable parts
