Stainless Tapered roller bearings S30206
Tapered roller bearings mainly bear combined radial and axial loads. Bearing capacity depends on the raceway Angle of the outer ring, the larger the Angle, the greater the bearing capacity. This kind of bearing is a separation type bearing, which can be divided into single row, double row and four row tapered roller bearings according to the number of rolling bodies in the bearing. Single row tapered roller bearing clearance shall be adjusted by the user during installation. Double row and four row tapered roller bearing clearance has been given according to user requirements when the product leaves the factory.
Tapered roller bearings have conical inner ring and outer ring raceway, tapered roller arranged between the two. The projection lines of all conical surfaces meet at the same point on the bearing axis. This design makes tapered roller bearings particularly suitable for combined (radial and axial) loads. The axial load capacity of the bearing is largely determined by the contact Angle alpha. The greater the Angle, the higher the axial load capacity. The Angle magnitude is expressed by the calculation coefficient e; The greater the e value, the greater the contact Angle, the greater the applicability of bearing to bear axial load. Tapered roller bearings are usually of separate type, that is, the tapered inner ring assembly composed of inner ring with roller and cage assembly can be installed separately from the tapered outer ring (outer ring). Tapered roller bearings are widely used in automobile, rolling mill, mining, metallurgy, plastic machinery and other industries.
The main reasons why tapered roller bearings are causing scratches in the process of installation are as follows: the inner ring and outer ring are askew during installation and assembly of bearings; Or it is in the process of the device and assembly of emerging from the front load, bearing emerging scars that can eventually form. Taper roller bearings are device should work in accordance with the specification when to stop, do not form many achievements, such as device or method not when, in the form of will form the bearing raceway surface formation and bone surface bearing linear scars that are emerging. The device of deep groove ball bearing indirectly reflects the precision, life and function of the bearing.
