Professional production CHROME STEEL 30311 30311RS 30311C2 55*120*31.5mm TAPPER ROLLER BEARING
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.
