Main uses and parameters of cylindrical roller bearings
Cylindrical roller bearings are mainly used in compressors, pumps, wind power equipment, gear boxes, unbalanced vibration exciter and other equipment.The main parameters of cylindrical roller bearings are the capacity of heavy load and high speed, and can bear axial displacement; it is separable design.
A lot of cylindrical roller bearing Luoyang Longma Bearing Co. Ltd. cylindrical roller bearing type, according to the structure, N, NF, NJ, NU, NUP, NCL, RN and RNU. There are normal and reinforced cylindrical roller bearings to be distinguished by load capacity. The shape dimension of reinforced cylindrical roller bearings is identical with that of the common type, but the roller diameter, length and quantity are increased, so the load capacity is increased. Single column and multi column cylindrical roller bearings are distinguished by the number of columns in cylindrical roller. Cylindrical roller bearing is divided into four row cylindrical roller and cylindrical roller radial, high bearing capacity, but can not bear the axial force, radial small size, high speed limit, because without inner ring ribs can be installed so that the inner and outer components respectively (with a full set of roller and cage). This kind of bearing has many advantages such as large radial bearing capacity, high rotating accuracy, easy installation and disassembly. The utility model is suitable for working rolls or supporting rolls of various hot and cold mills, blank mills, etc.
