Taper roller bearings mainly bear the combined radial and axial loads based on the radial direction. Its capacity depends on outer ring raceway angle.

All You Need to Know about Taper Roller Bearings [Quick]

Taper roller bearings mainly bear the combined radial and axial loads based on the radial direction. The bearing capacity depends on the raceway angle of the outer ring. The larger the angle, the greater the bearing capacity. This type of bearing is a separate bearing.

Users need to adjust the clearance of single-row tapered roller bearings during installation. The clearance of double-row and four-row tapered roller bearings has a fixed value at the factory. So, it does not require user adjustment.

Tapered roller bearings' angle

Tapered roller bearings have tapered inner and outer ring raceways. And tapered rollers are between the inner and outer rings. The projection lines of all cone surfaces converge at the same point on the bearing axis. The contact angle α determines the axial load capacity of most bearings. The larger the α angle, the higher the axial load capacity. Calculate the coefficient e to represent the angle. The greater the e value, the greater the contact angle. The greater the applicability of the bearing to bear the axial load.

Precautions for bearing use

No matter how high performance bearings you use, if you use improperly, bearings will not get the expected high performance. Therefore, there are several precautions for the use of bearings:

(1) Keep tapered roller bearings and their surroundings clean

Even small dust invisible to the eyes can have a bad effect on the roller bearing. Therefore, keep the surroundings clean to prevent dust from entering the bearing.

(2) Use with caution.

A strong impact on the tapered roller bearing during use will cause scars and indentations. So this will be the cause of the accident. In severe cases, it will crack or break, so be careful.

(3) Use appropriate operating tools.

Avoid replacing with existing tools, you must use appropriate tools.

(4) Pay attention to the corrosion of tapered roller bearings.

When handling bearings, sweat on your hands can cause rust. Pay attention to the operation with clean hands, it is best to wear gloves as much as possible.
