Single row bearings can bear radial load and unidirectional axial load, and double row bearings can bear radial load and bidirectional axial load.Suitable for bearing heavy load and shock load. This type of bearing is equipped with a round platform roller, the roller by the inner ring of the large rim.
Main applications of taper roller bearing：
Front wheel, rear wheel, transmission, differential pinion shaft. Machine tool spindles, construction machinery, large agricultural machinery, railway vehicle gear reducer, rolling mill roller neck and reducer.
Tapered Roller Bearings are designed to reduce friction and, in turn, reduce the heat that can cause bearing structures to fail. This bearing is used in many industrial applications and is optimal for those undergoing excess loads.
What types of loads can tapered roller bearings handle?
The angled and tapered shape of tapered roller bearings minimizes the stress caused by a combination of radial and axial loads. Radial and axial loads often combine to create different loads upon a bearing assembly. The ability to handle angular loads and changing angular loads – makes tapered roller bearings indispensable to various technical designs and industries. The tapered shape essentially concentrates radial and axial loads into a unified load that is more easily harnessed. Which angular loads can be harnessed depends on the precise angle of the tapered bearing. They can harness a comprehensive range of forces by configuring two or even more tapered bearings.
The steepness of the roller bearing's gradient increases the thrust/axial load it can handle, while a shallow angle increases the radial load capacity. As the radial load increases, the bearing experiences more stress against the sides of the bearing raceways. A more shallow angle minimizes stress, reducing pressure on the rollers. Increased axial load contributes to the stress applied to the top of the rollers. A steeper angle will distribute the pressure more towards the center of the bearing and less onto the rollers themselves.
Common uses of tapered roller bearings
A tapered roller bearing is appropriate wherever a bearing must handle combination loads. One of the most common uses is maintaining axial balance, achieved with multiple tapered roller bearings along an axle or shaft. The tapered bearings will evenly distribute loads when adequately aligned, minimizing wear and tear on the components. With higher surface area, tapered roller bearings can distribute friction and heat from combination loads more efficiently than non-tapered rollers (which are more efficient than tapered bearings only with the most straightforward non-combination forces). This reduced friction increases the rotational speed of interfacing parts and makes tapered roller bearings ideal for use in:
Engines
Motors
Gearboxes (especially those with helical gears)
Wheels & axles
Turbines & propellers
This equipment must combine many different angles and utilize them to drive motors, driveshafts, and other rotational components.
