Description 

300TQOS440-1  Tapered roller bearings are widely used in automotive, mill, mining, metallurgy, plastics machinery and other industries.

300TQOS440-1  Tapered roller bearings are mainly exposed to the radial diameter, axial load. Load bearing capacity depends on the outer ring raceway angle, angle the greater the bearing

300TQOS440-1  Carrying capacity greater. This kind of bearing is a separate type bearings, according to the number of columns bearing rolling elements into single row, double row and four-row tapered roller bearings. Single row tapered roller bearing clearance to be adjusted during installation; double row and four-row tapered roller bearing clearance in the factory based on user requirements given, not to be user adjusted.

Inch Tapered Roller bearing

1. Inch Taper roller bearing mainly bear radial primarily diameter, the axial load. Bearing capacity depends on the Angle of the outer ring raceway, the greater the Angle, the greater the carrying capacity. 

2. Inch Taper roller bearing type belongs to the separation bearing, , according to the bearing the number of columns of the scroll body can be divided into single row, double row and four row circular cone roller bearings.

3. Single row inch taper roller bearing clearance to users in the installation adjustment; Double row and four row circular cone roller bearings clearance has according to user requirements for a given when the products leave the factory, not the user. 

4.Tapered roller bearing are widely used in car: front-wheel, rear wheel, transmission, differential pinion shaft. Machine tool spindles, construction machinery, largescale agricultural machinery, railway vehicles, gear reduction, the rolling mill roll neck and deceleration devices

5. Equipment, instrument, building machinery, rolling stock agricultural machinery and various specialized machineries.
