2>Tapered Roller Bearings structural features:

    1.Separate bearing with conical rolling elements.

    2.Suitable for bearing large axial load and combined radial load.

    3.The conical surface of each rolling element of the bearing intersects at the same point on the axis,       so that the rolling elements can achieve pure rolling and reduce friction and wear;

    4.One inner (outer) ring of the same brand product can be used with several different outer (inner)          rings

    5.Double-row and four-row bearings can withstand higher loads and are mainly used in rolling mills       and trains in steel processing and copper processing plants;

3>The main applicable cages of tapered roller bearings.


The main applicable cages are: stamped steel cage (bowl shape...single row; shape, S crown shape...double row) copper alloy Or phenolic resin cutting cage, synthetic resin molding cage Main purpose: single row: machine tool spindle, high frequency motor, gas turbine, centrifugal separator, small car front wheel, differential pinion shaft, double row: oil pump, roots Four-point contact ball bearings for blowers, air compressors, various transmissions, fuel injection pumps, and printing machinery can withstand radial loads and bidirectional axial loads. 

A single bearing can replace the front combination or back combination angular contact ball bearings, suitable for bearing pure shafts A composite load with a large axial load or axial load component can form a contact angle (α) when bearing axial load in any direction. Therefore, the ring and the ball are always in contact with three points on both sides of any contact line. Mainly applicable cage: copper alloy cut cage. 

Main purpose: aircraft jet engine, gas turbine self-aligning ball bearing. Because the outer ring raceway surface is spherical, it has self-aligning performance, so it can automatically adjust due to the deflection of the shaft or shell. Bearings with an out-of-center tapered hole caused by curvature or misalignment can be easily installed on the shaft through the use of fasteners. Stamped steel cage: chrysanthemum
