Aligning ball bearings
Spherical roller bearings between the two raceways of the inner ring and the outer ring raceway is spherical, equipped with a drum-shaped roller bearings. Outer raceway curvature center and bearing center line, and so has the same self-aligning ball bearing self-aligning feature. Shaft shell deflection occurs, you can automatically adjust the load and axial load in two directions. Radial load capacity, suitable for heavy-duty impact load conditions. Inner diameter is tapered bore bearings can be installed directly. Or use tight sets demolition tube installed in the cylinder axis. Cage using steel stamping cage, polyamide forming cage and copper alloy machined cage.
Entity type needle roller bearings
The basic structure of the inner ring bearings NU-type cylindrical roller bearing the same volume can be reduced due to the use of needle, and can withstand large radial load bearing inner ring should have a suitable precision and hardness of the shaft of the mounting surface as raceway use.
Thrust needle roller bearings
Separation-bearing raceway ring and needle roller and cage assemblies, and any combination of processing and stamping thin raceway ring (W) or thick cut processing raceway ring (WS). Non-separable type bearings are constituted by the machining precision stamping raceway ring needle roller and cage assemblies overall bearing. Kind of bearings can withstand axial load. Small footprint, the compact design of machinery, mostly only needle roller and cage assemblies, and the mounting surface of the shaft and housing as a raceway.
Tapered Roller Bearings
These bearings are equipped with a truncated cone-shaped roller, roller guided by the inner ring ribs. Designed so that the inner ring raceway, the outer ring raceway surface and the roller rolling surface of each of the vertex of the conical surface intersecting at the point of the bearing center line. Single row bearings can bear radial load and axial load, double row bearings can bear radial load and bidirectional axial load, applies to withstand heavy load and impact load.
Cylindrical roller bearings
According to the rolling element bearing equipped with a different number of columns, cylindrical roller bearings can be divided into single row, double row and multi-row cylindrical roller bearings. The application of more cage single row cylindrical roller bearings. In addition, there are single-row or double row full complement roller other structure of cylindrical roller bearings.
Single row cylindrical roller bearing divided into N-type ring ribs, NU, NJ, NF and NUP type. Cylindrical roller bearings under radial load capacity, according to the structure of the ring wall can withstand a certain amount of one-way or two-way axial load.
NN and NNU type double row cylindrical roller bearings compact structure, strong rigidity, load capacity, small deformation under load, mostly for machine tool spindle bearing.
FC, FCD FCDP four cylindrical roller bearings can withstand greater radial load, and more for the mill and other heavy machinery.
Spherical roller bearings
Kind of bearing between the the spherical raceway outer ring and the double raceway inner ring fitted with spherical roller different internal structure, divided into R, RH, RHA and SR, four types. Since the outer ring raceway arc center and bearing center line, aligning performance, so you can automatically adjust the axis caused due to the deflection of the shaft or housing or different heart is not right. Radial load and axial load. Radial load capacity, suitable to withstand heavy shock load.
Tapered bore bearings on the shaft through the use of fasteners or withdrawal sets allows assembly and disassembly. Spherical roller bearings can withstand greater radial load, also can withstand a certain amount of axial load. Kind of bearing outer ring raceway is spherical, so aligning performance when curved or tilted axis force leaving the inner ring centerline and the outer ring of the centerline relative inclination of not more than 1 ° ~ 2.5 °, the bearing can still work .
Thrust roller bearings
Thrust Roller Bearings Thrust Spherical roller bearings, cylindrical roller thrust bearings and thrust tapered roller bearings. Thrust Spherical roller bearings can withstand axial and radial load, but the radial load should not exceed 55% of the axial load. Another important characteristic of the type of bearing away with self-aligning performance, so it is not very sensitive to misalignment and shaft deflection. As long as the load P and P. No more than 0.05C, shaft ring rotation bearings to allow a range of aligning angle. Small value for large bearings, but also allow aligning angle will decrease the load increases.
Spherical bearings
Spherical bearings priority for applications that require simple equipment and spare parts of occasions, such as for agricultural machinery, transportation systems or construction machinery. Mainly used to bear radial load mainly radial and axial load, and in general should not alone bear the axial load, such bearings can be installed inner ring (roller retainer with the whole group) and the outer ring. This kind of bearing does not allow the shaft relative to the housing tilt will produce additional axial force, radial load appointment. The size of the bearing axial clearance bearing can work in it, when the axial clearance is too small, the higher temperature; axial clearance is large, easy to damage bearings. Therefore, you want to pay special attention to the installation and operation of adjusting bearing axial clearance, preloaded mounting necessary to increase the rigidity of the bearing
