Deep groove ball bearings The most representative of the rolling bearings, versatile, can withstand radial load brass bushings and two-way axial load. Suitable for high-speed rotation and the requirements of low noise, low vibration occasions with steel dust cover or rubber seal seal bearing pre-filled with the right amount of grease, the outer ring with a retaining ring or flange bearings, To the positioning, but also easy to install within the shell. The maximum load bearing size and standard bearing the same, but inside and outside the deep groove ball bearing the most representative of the rolling bearing, versatile, can withstand radial load and two-way axial load.

Suitable for high-speed rotation and the requirements of low noise, low vibration bronze hole bearing occasions with steel dust cover or rubber seal seal bearing pre-filled with the amount of grease, the outer ring with a ring or flange bearing , That is easy to axial positioning, and easy to install within the shell. The maximum load bearing size is the same as the standard bearing, but the inner resin-based steel ball retaining ring outer ring has a trough, which increases the number of balls and improves the rated load. Self-aligning ball bearings Spherical roller bearings in the two raceway inner ring and raceway for the spherical outer ring, equipped with drum roller bearings. The center of curvature of the outer raceway surface is the same as that of the bearing center, so it has the same self-aligning function as the self-aligning ball bearing.

In the shaft, the shell appears to flex, you can automatically load and the two directions of the axial load. Radial load capacity, suitable for heavy load, the impact of the situation. Inner diameter is the tapered bore, can be installed directly. Or the use of adapter sets, the removal of the cylinder mounted on the cylindrical shaft. The cage uses steel plate stamping cage, polyamide forming cage and copper alloy car cage. Needle roller bearings Solid type needle roller bearings with inner ring bearing the basic structure and NU cylindrical roller bearings the same, but due to the use of needle roller, the volume can be reduced, and can withstand large radial load without inner ring bearings should have the appropriate accuracy And the mounting surface of the hardness of the shaft is used as the raceway surface.

Thrust needle roller bearings Separate bearings are made up of roller rings and needle roller and cage assemblies, and can be combined with stamping machined thin raceway (W) or cut machined thick raceway (WS). Non-separable bearings are made of precision stamping of the roller ring and needle roller and cage components of the overall bearing. Can withstand one-way axial load of this type of bearing. Space is small, is conducive to the mechanical compact design, most of the use of needle roller and cage components, and the shaft and shell mounting surface as a raceway surface use. Tapered roller bearings This type of bearing is equipped with rounded roller, the roller is guided by the inner ring.

So that the vertex of the conical surface of the inner raceway, the outer raceway surface and the roller rolling surface intersects the point on the center line of the bearing. Single row bearings can withstand radial load and unidirectional axial load, double row bearings can withstand radial load and two-way axial load, suitable for heavy load and impact load. Cylindrical roller bearings According to the number of roller bearings installed in different bearings, cylindrical roller bearings can be divided into single row, double row and multi column cylindrical roller bearings. Which is more applications are a single row of cylindrical roller bearings.

In addition, there are single or double row full complement roller and other structures of the cylindrical roller bearings. Single row cylindrical roller bearings are divided into N type, NU type, NJ type, NF type and NUP type according to the different ring rims. Cylindrical roller bearings bear the radial load capacity, according to the structure of the ring rib can also bear a certain one-way or two-way axial load. NN type and NNU double row cylindrical roller bearings compact structure, strong rigidity, load capacity, by the load after the deformation is small, mostly for the machine tool spindle support.

FC, FCD, FCDP four-row cylindrical roller bearings can withstand large radial load, and more for heavy machinery such as rolling mill. Spherical roller bearings The bearings in the spherical roller raceway and double raceway between the inner ring There are spherical roller, according to the internal structure of the different, divided into R, RH, RHA and SR four types.

As the outer ring raceway center of the arc and the center of the same bearing, with self-aligning performance, it can automatically adjust the shaft or shell deflection or disorientation caused by the axis of the incorrect. Can withstand radial load and two-way axial load. Especially radial load capacity, suitable for heavy load and impact load.

Tapered bore bearings can be mounted on the shaft by using fasteners or withdrawal sleeves. Spherical roller bearings can withstand a larger radial load, but also can withstand a certain axial load. This type of bearing outer ring raceway is spherical, it has a self-aligning performance, when the axis of bending or bending force so that the inner ring center line and the outer ring centerline relative tilt of not more than 1 ° ~ 2.5 °, the bearing can still work The Thrust Roller Bearings Thrust Roller Bearings include thrust spherical roller bearings, thrust cylindrical roller bearings and thrust tapered roller bearings. Thrust spherical roller bearings can withstand axial and radial loads at the same time, but the radial load must not exceed 55% of the axial load. Another important feature of this type of bearing is that it has self-aligning performance, so it is less sensitive to different heart and shaft deflections. As long as the load P and P.

Not more than 0.05C, and the shaft rotation, the bearing allows a certain range of aligning angle. Small values ​​apply to large bearings, and when the load increases, the centering angle is allowed to decrease. Spherical bearings Spherical bearings are preferred for applications where equipment and components are simple, such as for agricultural machinery, transport systems or construction machinery. Mainly used to bear the radial load-based radial and axial joint load, generally not alone to bear the axial load, such bearings can be installed inner ring (with the whole group of rollers and retainers) and outer ring. The bearing does not allow the shaft to be tilted relative to the housing, with additional axial force under radial load. The bearing axial clearance of the size of the bearing can work a great relationship, when the axial clearance is too small, the temperature rise higher; axial clearance is large, the bearing is easy to damage.

So in the installation and operation should pay special attention to adjust the bearing axial clearance, if necessary, can be pre-installed to increase the rigidity of the bearing. Spherical plain bearings are lubricated and self-lubricated. Spherical plain bearings are a special type of plain bearings. Its structure is simpler than the rolling bearing, which is mainly composed of an inner spherical outer ring, can withstand a larger load, according to a spherical outer ring and its different types and structures, can withstand radial load , Axial load or radial, axial simultaneous co-load.

Generally used for low-speed swing movement (ie, angular shape, can also be tilted within a certain range of motion (ie, self-aligning movement), due to the sliding surface of the spherical surface), the support shaft and shaft shell hole Larger, still able to work properly. Linear bearings Linear motion ball bearings are mainly used in the mechanical equipment in the linear reciprocating parts, with a small friction, flexible movement and easy to replace the advantages of maintenance.

It is widely used in textile machinery, printing machinery, pharmaceutical machinery, precision machine tools, electrical cutting machine and automatic recorder and other fields. Angular contact bearings Angular contact ball bearings, which can withstand radial load and axial load, can also be with the pure axial load, the higher the speed limit. The ability of such bearings to withstand axial loads is determined by the contact angle, with high contact angles and high axial load capacity.

Pressure bearing pressure bearing is a separate bearing, according to its structure is divided into one-way pressure ball and two-way pressure ball bearings. Unidirectional pressure bearings can withstand axial load in one direction, and two-way pressure bearings can withstand axial loads in both directions. They can not withstand radial loads.
