Tapered Roller Bearing:31305

Description

Characteristics

1.Can withstand large radial and axial loads at the same time: due to the special shape of the tapered roller, it has a unique advantage when bearing loads.
2. Adapt to high-speed operation: the reasonably designed tapered roller bearing can work at a higher speed.
3. High precision: can provide high rotation accuracy, reduce vibration and noise.
4. Easy installation and adjustment: the clearance of the bearing can be adjusted to meet different working requirements.

Classification

1.Single-row tapered roller bearings: composed of an inner ring, an outer ring and a group of tapered rollers, which can withstand unidirectional radial and axial loads.
2. Double row tapered roller bearings: there are two rows of tapered roller bearings, which have stronger bearing capacity and can withstand two-way radial and axial loads.
3. Four-row tapered roller bearings: mainly used for special occasions such as heavy machinery, with great carrying capacity.

 

Basic Parameters

1.Inner diameter, outer diameter and width: determine the mounting size of the bearing.
2. Rated dynamic load and rated static load: characterizes the bearing capacity.
3. Limit speed: indicates the highest speed that the bearing can safely operate under certain conditions.
4. Contact Angle: The Angle between the tapered roller and the raceway affects the bearing capacity and axial force bearing capacity.

The Working Principle

Tapered roller bearings roll between the inner and outer ring raceways when working. When the bearing is stressed, the roller transfers the load to the raceway, and because of the special shape of the roller, the bearing can bear both radial and axial loads. At the same time, by adjusting the bearing clearance, the normal operation of the bearing can be ensured under different working conditions.

 

Application Fields

1.Automotive field: used in the wheel hub, transmission and other parts of the car.
2. Industrial machinery: such as machine tools, motors, fans, etc.
3. Mining machinery: widely used in crusher, conveyor and other equipment.
4. Agricultural machinery: such as tractors, harvesters, etc.
5. Heavy machinery: such as cranes, excavators, etc.
