Stainless steel taper roller bearing S30208
Stainless steel tapered roller bearings are in the process of the installation of the secondary cause of the emergence of scars: the bearing is in the installation, assembly of the inner ring, the outer ring askew; Or it may be a surge charge load in the process of installation and assembly, resulting in the emergence of bearing scars.
Tapered roller bearings are installed in accordance with the work specifications to stop, will not form a lot of results, such as the device form or method is not appropriate, will form the raceway surface of the bearing and the bone surface of the bearing to emerge linear wounds. The device of deep groove ball bearing indirectly reflects the precision, life and function of the bearing.
The stainless steel tapered roller shaft mainly bears radial combined radial and radial 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.
Stainless steel 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).
