Why do we need to choose tapered roller bearings?

In some machine tool applications with heavy loads and certain speed requirements, such as forgings, threading machines for oil pipelines, heavy-duty lathes and milling machines, it is an ideal solution to choose precision tapered roller bearings.

What are the usage parameters of tapered roller bearings?

1. Allowable installation inclination: Generally, tapered roller bearings are not allowed to incline between the shaft center line and the seat hole, and the maximum cannot exceed 2'. Otherwise, it will cause uneven force on the contact surface between the rolling element and the raceway during operation, which will affect the bearing life.

2. Allowable temperature: Under normal working load conditions, the lubricant with high temperature resistance is selected and the lubrication is sufficient. Generally, the bearing is allowed to work at an ambient temperature of -30°C~+150°C.

3. Working clearance: The working clearance of the bearing has a great influence on the friction temperature rise, the running accuracy and the rigidity of the bearing. Adjusting to a suitable working clearance has an important influence on the service life of the tapered roller bearing. During the installation process, it is necessary to measure the internal clearance of the bearing at any time to ensure that the bearing obtains the most suitable working clearance or preload.

What are the common tapered roller bearings on the market?

1. The outer ring (or inner ring) of a double row tapered roller bearing is a single piece. The small end faces of the two inner rings (or outer rings) are similar, and there is a spacer in the middle. The clearance is adjusted by the thickness of the spacer. The thickness of the spacer can also be used to adjust the pre-interference of the double-row tapered roller bearing.

2. Four-row tapered roller bearing, the performance of this type of bearing is basically the same as that of double-row tapered roller bearing, but the radial load is larger than that of double-row tapered roller bearing, and the limit speed is slightly lower, mainly used for heavy machinery.

3. Multi-sealed double and four-row tapered roller bearings. These are long-life, multi-sealed double, four-row tapered roller bearings. We carry out a new personalized design for bearings, change the traditional design method of fully sealed bearings, and adopt a new type of sealing structure that combines sealing and dust-proofing to improve the sealing effect and improve the sealing performance. Compared with the open structure bearing, the multi-sealed double-row and four-row tapered roller bearings have a 20% to 40% increase in service life and an 80% reduction in lubricant consumption.

What are the characteristics of the use of tapered roller bearings?

1. It is suitable for heavy-duty mechanisms or mechanisms with shock loads.

2. Can bear radial load and axial load at the same time

3. The tapered roller bearing will have an axial force component, so it needs to be used in pairs

4. The running speed is not suitable for high speed

5. Good lubrication is required, preferably oil bath lubrication
