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.

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
