Cylindrical roller bearing
Collect
Cylindrical roller bearing rolling body for the cylindrical roller, belong to the separable bearing, convenient installation and disassembly. According to the collar with or without retaining edge, can be divided into N, NU, NJ, NF, NUP and other single row cylindrical roller bearings, and NNU, NN and other double row cylindrical roller bearings, in addition to multi-row cylindrical roller bearings. Cylindrical roller bearings generally use copper alloy turning entity keep frame or engineering plastic keep frame, when the speed is low load, can be designed into no keep frame full roller structure. Cylindrical roller bearing roller and raceway for line contact, load capacity, mainly bear radial load. Rolling body and the sleeve edge friction is small, suitable for high-speed rotation, the use of coaxiality requirements are high. Inner ring or outer ring without baffle cylindrical roller bearing, its inner ring and outer ring can be axially for relative movement, so can be used as a free end bearing. In the inner ring and outer ring of a side of the double edge, the other side of the collar has a single edge of the cylindrical roller bearing, can bear a certain degree of single direction axial load. Product characteristics Separable inner or outer rings for easy mounting and dismounting; Large radial load carrying capacity, suitable for bearing heavy loads and shock loads; small coefficient of friction, suitable for high speed, limit speed close to deep groove ball bearings; N and NU type can be moved axially, can be used as free end support; The processing requirements of the shaft or seat hole are high, to prevent relative deflection, so as not to cause contact stress concentration. Main fields Large and medium-sized motors, rolling stock, machine tool spindles, internal combustion engines, generators, gas turbines, reduction gearboxes, rolling mills, vibrating screens and lifting and transport machinery. |
