Product introduction
30311 ability of single row tapered roller bearing to bear axial load depends on the contact angle, that is,the outer ring raceway angle, the larger the angle, the greater the axial load capacity. Tapered roller bearings are mainly used to bear radial load mainly radial and axial combined load. Compared with the angular contact ball bearing,
Application of Inch tapered roller bearing:
Inch tapered roller bearings are widely used in automotive, rolling mills, mining, metallurgical,
plastic machinery, etc.
