Taper Roller Bearing 30308

Single-row tapered roller bearings have an outer ring and an inner ring assembly of which the inner ring and a set of tapered rollers are enclosed by a basket cage. The outer ring can be separated from the inner ring assembly. According to the ISO tapered roller bearing dimension standard, the outer ring or inner ring assembly of any standard type of tapered roller bearing should achieve international performance with the same type of outer ring or inner ring assembly. exchange. That is to say, the outer ring of the same type must comply with the ISO492 (GB307) regulations in addition to the external dimensions and tolerances, and the cone angle of the inner ring component and the diameter of the component cone must also comply with the relevant regulations for interchangeability.

Single-row tapered roller bearings have an outer ring and an inner ring assembly of which the inner ring and a set of tapered rollers are enclosed by a basket cage. The outer ring can be separated from the inner ring assembly. According to the ISO tapered roller bearing dimension standard, the outer ring or inner ring assembly of any standard type of tapered roller bearing should achieve international performance with the same type of outer ring or inner ring assembly. exchange. That is to say, the outer ring of the same type must comply with the ISO492 (GB307) regulations in addition to the external dimensions and tolerances, and the cone angle of the inner ring component and the diameter of the component cone must also comply with the relevant regulations for interchangeability.

Generally, the taper angle of the outer ring raceway of a single-row tapered roller bearing is between 10° and 19°, which can bear the combined effect of axial load and radial load at the same time. The larger the cone angle, the greater the ability to bear the axial load. Bearings with large taper angle, postcode plus B, and taper angle between 25°~29° can bear large axial load. In addition, single-row tapered roller bearings can adjust the size of the clearance during installation.
