Cylindrical roller bearings

According to the rolling element Roller bearing mounted with different number of columns, cylindrical roller bearings can be divided into single row, double row and multi-row cylindrical roller bearings. Which is the application of more cage row cylindrical roller bearings. In addition, single or double row full complement cylindrical roller and other structures of cylindrical roller bearings.Single row cylindrical roller bearings under the ring ribs divided into N-type, NU type, NJ-type, NF-and NUP type. Cylindrical roller bearings under radial load capacity, according to the structure of ring wall can withstand a certain one-way or two-way axial load.
NN and NNU type double row cylindrical roller tapered bearing  compact structure, strong rigidity, load capacity, after the deformation under load, mostly for machine tool spindle bearing.
FC, FCD, FCDP type four-row cylindrical roller bearings can withstand higher radial loads, and more for rolling mills and other heavy machinery.
Spherical Roller Bearings
The bearing outer ring with spherical raceway in the inner ring raceway fitted between double spherical roller, according to the different internal structure, divided into R, RH, RHA and four types of SR. Since the outer ring raceway of circular arc center and bearing center line, with self-aligning properties, it can automatically adjust the shaft or housing deflection or misalignment of axis errors caused. Can bear radial load and axial load. Especially the radial load capacity, suitable to withstand heavy load and shock load.
Tapered bore bearings through the use of fasteners or withdrawal sleeves can make the shaft assembly and disassembly. Spherical roller bearings can withstand greater radial load, but also bear certain axial load. This kind of bearing outer ring raceway is spherical shape, aligning it with the performance, when the axial force leaving the inner bend or tilt tilted relative to the center line and the center line of the outer ring does not exceed 1 ° ~ 2.5 °, the bearing can still work .
Thrust roller bearings
Thrust roller bearings, including spherical roller thrust bearings, thrust cylindrical roller bearings and tapered roller thrust bearings. Axial spherical roller bearings can withstand axial and radial load, but the radial load should not exceed 55% of the axial load. Another important feature of this type of bearing away is a self-aligning performance, so to the degree of misalignment and shaft deflection less sensitive. As long as the load P, and P. No more than 0.05C, and turn rotary shaft, bearings allows a range of self-aligning angle. Small values ​​for large bearings, and load increases to allow aligning angle will decrease.
