Tapered 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, greater perspective carrying capacity is bigger. These bearings are separated type bearings, according to belong in the roller bearing the column number to be mounted, double row and four row circular cone roller bearings. Taper roller bearing clearance single user when installation should adjust; Double row and four row circular cone roller bearings clearance has the products leave the factory based on user requirements are given, not the user to resize.
A conical taper roller bearing outer ring groove and inner circle, tapered roller are arranged in between. All the conical surface in bearing axis projection line the same point again. This design makes tapered roller bearing composite (particularly suited to bear radial and axial) load. Bearing axial load ability most is decided by the contact Angle is alpha; Alpha greater perspective, axial load capacity is higher. Angle size by calculating coefficient e to say; E value, the greater the contact Angle, the bigger the axial load bearing the greater the applicability.
Taper roller bearings are usually separated type, namely the belt roller and maintains a component within the cone of circles within circles conical outer components can and outer ring) apart installation (.

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.

Angle contact ball bearing
Angle contact ball bearing can be both radial load and axial load. Can work under at higher speed. Contact Angle is, the greater the axial bearing capacity is higher. High precision and high-speed bearing usually take 15 degrees contact Angle. Under the action of the axial force, contact Angle increases. Single Angle contact ball bearing can only carry axial load in one direction, in radial load, will cause additional axial force. And only limit shaft or shell in a direction of the axial displacement. If quality.the installation, make a pair of bearings, namely the outer ring relatively wide wide end, narrow face the narrow end face. So we can avoid cause additional axial force in both directions, but also in the shaft or shell limit axial clearance range. Angle contact ball bearing outer ring inside the groove because there can be in a horizontal axis relative displacement, so can both radial load and axial load - union load (single Angle contact ball bearing single direction can only carry axial load, so usually paired often adopted installed). Maintains a material has brass, synthetic resins, the bearings form, in accordance with the using conditions and divisional. Angle contact ball bearing are: 7000C type (∝ = 15 °), 7000AC type (∝ = 25 °) and 7000B ∝ = 40 °) (several types. The bearing outer ring in the lock on the mouth, generally can‘t be separated from internal and external circle and can withstand radial and axial load and a combination of direction of the axial load. Axial load capacity by contact Angle, contact Angle decision is the ability of axial load high. The bearing can restrict shaft or shell in a direction of the axial displacement.
