"Rolling NSK Bearings"
Most representative of the rolling NSK bearings, widely used, affordable, two-way radial load and axial load.
Requirements for high-speed rotation and low noise, low vibration of the occasion with a steel or rubber ring seal Shield type NSK bearing pre-filled with the right amount of grease, the outer ring with snap ring or flange bearing, that is easy to axial location, but also easy to install inside the enclosure.
Maximum load-type bearing the size of a standard bearing the same, but inside and outside the ring there is a slot loading, an increase of the number of loading the ball to improve the rated load.
"Self-aligning ball bearings,"
Self-aligning roller bearings have two raceways in the inner and outer ring raceways between spherical, equipped with drum-shaped roller bearings.
The outer ring raceway curvature center and bearing center line, so has the self-aligning ball bearings the same tone of cardiac function.
In the shaft, shell deflection occurs, you can auto-load and the two axial load direction.
Radial load capacity, applicable to heavy load, shock load conditions.
Inner diameter is tapered bore bearings can be installed directly. Or use the adapter sleeve, demolition tube installed in the cylinder axis. Cage sheet metal stamping cage, polyamide forming cage and copper alloy cage car system.
"Needle Roller Bearing"
Entity-type needle roller bearings
The basic structure of a bearing inner ring and the NU type cylindrical roller bearings the same, but due to the needle, the volume can be reduced, and can withstand large radial loads without bearing inner ring should have the appropriate accuracy and hardness of the shaft of the mounting surface as the raceway to use.
Thrust needle roller bearings
Separate bearing raceway ring from the cage with the needle and the components can be processed with the stamping thin raceway ring (W) or thick-cut system for processing raceway ring (WS) any combination.
Non-separable type bearings are processed by punching through the precision raceway ring and the needle roller and cage components of the overall bearing. Can withstand such a one-way axial load bearing. Space is small, compact machine designed to benefit, mostly using only needle roller and cage assemblies, while the shaft and installation of the shell used as a raceway.
"Tapered Roller Bearing"
Type of bearing is equipped with truncated cone-shaped roller, roller guided by the inner ring large rib. The design makes the inner raceway, outer raceway and the roller rolling surface of the apex of the conical surface intersect at a point bearing center line.
Single row bearings can bear radial load and a one-way axial load, double row bearings can bear radial load and bi-directional axial load applied to withstand heavy load and shock loading.
"Cylindrical roller bearings,"
Rolling bearing mounted in accordance with the number of columns in a different body, cylindrical roller bearings can be divided into single row, double row and multi-row cylindrical roller bearings.
In which applications are more separate cage cylindrical roller bearings. In addition, there is a single column or double row full complement roller and other structures of the cylindrical roller bearings.
Single row cylindrical roller bearings under the ring ribs divided into N-type, NU type, NJ-type, NF-and NUP type and so on. Cylindrical roller bearings to bear radial load capacity, according to the structure of ring wall can withstand a certain degree of one-way or two-way axial load.
NN-and NNU-type double row cylindrical roller bearings compact structure, rigidity, load capacity, deformation under load after the small, mostly for machine tool spindle bearing.
FC, FCD, FCDP-type four-row cylindrical roller bearings can withstand greater radial load, used for rolling mill and other heavy machinery.
"Self-aligning roller bearings,"
Type of spherical bearings in the outer ring raceway and inner raceway fitted between pairs of spherical roller, according to the different internal structure, is divided into R, RH, RHA, and SR four kinds of patterns.
As 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 a different axis errors caused by heart.
Can bear radial load and bi-directional axial loads. In particular, the radial load capacity, suitable to withstand heavy load and shock loading. Tapered bore bearings through the use of fasteners or a withdrawal sleeve allows the shaft of the Assembly and Disassembly.
Self-aligning roller bearings can withstand greater radial load, but also be able to withstand a certain degree of axial load. Type of bearing outer ring raceway is spherical shape, hence the self-aligning properties, when the axial force bending or tilt Ershi inner and outer ring of the centerline of the centerline of the relative inclination of not more than 1 ° ~ 2.5 °, the bearing still working .
"Thrust Roller Bearing"
Thrust roller bearings, including thrust-aligning roller bearings, thrust cylindrical roller thrust bearings and tapered roller bearings.
Thrust Self-aligning roller bearings can withstand axial and radial loads simultaneously, but the radial load shall not exceed 55% of axial load. Another important feature of these bearings away is a self-aligning performance, so make it different and the heart of a less sensitive to the deflection axis. As long as the load P and P. No more than 0.05C, and the shaft ring rotation bearings allows a range of self-aligning angle. Small values for large bearings, and the load increases, to allow self-aligning angle will be reduced.
"Outer Spherical Bearing"
Spherical Bearings priority for applications that require simple equipment and spare parts occasions, such as for agricultural machinery, transportation systems or construction machinery. Is mainly used to bear radial load mainly radial and axial joint load, the general should not alone bear the axial loads, such bearings can be mounted on the inner (with the entire set of roller and cage) and the outer ring.
This kind of bearing does not allow the relative shell-axis has tilted in the radial load will produce the next appointment of additional axial force.
This kind of bearing axial clearance of the size of the normal working relationship between the bearing ability, and when the axial clearance off hours, temperature is higher; axial clearance is large, easy to damage bearings.
Therefore, when installation and operation of special attention to adjust the bearing axial clearance, if necessary, the interference can be pre-installed in order to increase the bearing rigidity.
"Spherical Plain Bearings"
Joint bearings are lubrication-type and self-lubrication type. Articular bearing is a special structure of the sliding bearing.
Its structure is simpler than the rolling bearing, the main by a spherical outer ring within a composition, can withstand a greater load, according to which have outside the sphere of inner ring and its different types and structures that can bear radial load, axial load or radial, axial joint load exist.
Are generally used for slower swing movement (ie angle-shaped transportation is also available at a certain angle to tilt within the movement (ie, self-aligning movement), due to sliding surface of the sphere movement), in supporting shaft axis and a different heart of a shell-hole large, it can still work properly.
"Linear Bearings"
Linear motion ball bearings is mainly used in machinery and equipment in the linear reciprocating motion of the parts, with little friction, exercise flexibility and easy maintenance and replacement and so on.
It is widely used in textile machinery, printing machinery, pharmaceutical machinery, precision machine tools, electrical cutting machine and automatic recorders and other fields.
"Angular Contact Bearings,"
Angular contact ball bearings can bear radial load and axial at the same time the load can also be as pure axial load, the higher speed limit. Type of axial load bearing capacity of the decision by the contact angle, contact angle large, the ability to withstand high axial loads.
"The pressure bearing"
Pressure bearings are separated type bearings, according to its structure is divided into one-way pressure on the ball and two-way stress ball bearings.
A one-way bearings can withstand the pressure of the axial load in one direction, two-way bearings can withstand the pressure of the axial load in both directions.
They can not bear radial load.
