Taper roller bearings
Taper roller bearings which mainly bear with radial primarily diameter, the axial union load. Bearing outer ring rolling bearing capacity depends on the way Angle, the larger Angle bearing capacity is bigger. These bearings are of separated type bearings, according to the roller bearing in the column number to be mounted, double row and four row circular cone roller bearings. Single tapered roller bearing clearance to users in when installation, adjustment, Double row and four row circular cone roller bearings clearance already in product factory according to user requirements are given, not the user to resize.
Taper roller bearings taper inner ring and outer ring have groove, tapered roller are arranged in between. All taper surface projection lines are the same point in bearing axis reunion. This design makes tapered roller bearings specially suitable for composite (bear) radial and axial load. Bearing axial load ability is mostly decided by the contact Angle is alpha, Alpha greater perspective, axial load capacity is higher. Angle size by calculating coefficient e to say, E is, the contact Angle is, the bigger the bearing axial load applicability is greater.
Taper roller bearings are usually separated type, namely the belt roller and maintains a module of the inner ring of conical inner ring and outer ring (components can conical outer ring) apart installation.
Taper roller bearings are widely used in automobiles, rolling mill, mining, metallurgical, plastic machinery, etc.

Cylindrical roller bearing
Cylindrical roller bearing genera, separated type bearings and snuck. Cylindrical roller bearing be mounted, double row and four columns. According to the roller bearing outfit column number with different, cylindrical roler bearings can be divided into separate, double row and multicolumn cylindrical roller bearing. Among them are widely applied to keep the aircraft single cylindrical roller bearings. In addition, still with single or double row of other structures installed roller cylindrical roller bearing. According to single cylindrical roller bearing collar divided into raised edge of n-type, NU type, floatation type, NF type and NUP type, etc. Cylindrical roller bearing radial direction load capacity, according to the structure also raised edge collar we can withstand the one-way or two-way axial load. NN by type and NNU type double row cylindrical roller bearing compact structure, strong rigidity, load carrying capacity, distortion, mostly for spindle support. FC, FCDP type FCD, four row cylindrical roler bearings may withstand the big radial direction load, more for mill, etc. heavy machinery. Cylindrical roller bearing is mainly used in motor, machine tool, oil, mill loading/unloading machine and all kinds of industrial machinery.

Joint bearing
節(jié)軸承.jpg)
Joint bearing is a kind of special structure of sliding bearings. Its structure than rolling bearing simple, its main is by a spherical outside of the inner ring and outer ring inside the ball with a composed, can bear larger load, according to its different type and structure, can bear radial load, axial load or radial, axial and existing joint load. Generally used to speed the lower swing motion (namely Angle motion), with the sliding surface, also can be for spherical shape within the scope of certain Angle for tilt movement (i.e. self-aligning movement), in the axis and shaft shell holes concentricity bigger when, still can work normally. Joint bearing is a kind of special structure of sliding bearings.

Thrust ball bearings
Thrust ball bearings by a list of steel ball (with keep frame), a shaft circle (and shaft tight fit) and a seat ring (and shaft bearing hole with a gap and a tight fit) composition, steel ball on the shaft lap and seat ring between rotation. Can bear a direction of the axial load, cannot bear radial load. Due to the axial load is evenly distributed in each ball, so load capacity bigger; But work, larger, allowed temperature limit speed is low. Thrust ball bearings can limit the radial shaft or shell, but it can limit moving in the direction of axial and shell a axial movement, thus, such bearing usually and deep groove ball bearing joint use. Thrust ball bearings is separated type bearings, according to its structure form into i.e.one-way thrust ball and two-way thrust ball bearings. I.e.one-way thrust ball bearings can withstand a direction of the axial load, two-way thrust ball bearings can withstand the two directions of the axial load. They are unable to bear radial load. Thrust ball bearing and insert pads structure, due to the installation of seat cushion, so bearing angled spherical shape with self-aligning performance, can reduce the influence of installation error. Thrust ball bearings are used in automobile, machine tools, etc.

Deep groove ball bearing
Deep groove ball bearing is the most commonly used rolling bearings. Its simple structure and easy to use. Mainly used to bear radial load, but when increase bearing radial clearance, has certain Angle contact ball bearing performance, can withstand diameter, the axial union load. High in speed and unfavorable use thrust ball bearings, and it can also be used to withstand pure axial load. And the same size as compared with other types of bearings, such bearing small friction coefficient, extreme high speed. But don‘t impact resistance, not suitable for under heavy load. Deep groove ball bearing installed in shaft, in bearing axial clearance can restrict, within the scope of the shaft or shell axial displacement two directions, so it can be axial orientation. Two-way In addition, these bearings are still has certain self-aligning ability, when compared with housing holes‘, ‘tilt 2 and still ~ 10, but can work normally have certain influence to bearing life. Deep groove ball bearing maintains a more for stamping steel wave shape keep frame, large bearings used more car manufacturing metal entity keep frame. Deep groove ball bearing widely used in automobiles, tractors, machine tools, electric motors, pumps, agricultural machinery, textile, machinery, etc.
