Double row Spherical roller bearing with a withdrawal sleeve

The use of the withdrawal sleeves further enhances the adaptability and installation convenience of the double-row spherical roller bearing. By using the withdrawal sleeves, the tapered inner hole self-aligning ball bearing can be easily and quickly assembled on the smooth shaft or stepped machine shaft. This design makes the installation and removal process of the bearing easier, while also improving the service life and performance stability of the bearing.

In general, the characteristics of the double-row spherical roller bearing with withdrawal sleeves make it an efficient and reliable bearing solution, especially suitable for applications that need to withstand heavy loads and impact loads.

Features and advantages of QIBR double-row spherical roller bearings with withdrawal sleeves

QIBR double-row spherical roller bearings with withdrawal sleeves have solved many key problems in various fields, which are mainly reflected in the following aspects:

1. Self-aligning ability

The raceways of the inner and outer rings of double-row spherical roller bearings with withdrawal sleeves are curved, and the bearings have the function of self-aligning, that is, they can automatically compensate for the angular deviation caused by the bending of the shaft or the installation error. Therefore, it can withstand a certain axial load while bearing radial loads, and is particularly suitable for applications with low requirements for installation accuracy.

2. Strong load-bearing capacity

The rollers of double-row spherical roller bearings with withdrawal sleeves are cylindrical or slightly inclined, with a large contact surface, and can withstand large radial loads and bidirectional axial loads. Due to the large number of rollers, it has a higher load-bearing capacity, especially in high-load and high-impact application scenarios, and performs outstandingly.

3. Suitable for harsh working conditions

This type of bearing is often used in harsh environments such as high temperature, high speed, and heavy load, and can operate reliably under relatively harsh working conditions. Double-row spherical roller bearings with withdrawal sleeves are highly adaptable and can accommodate large axial offsets and radial load changes.

4. Easy to install and remove

The design of the withdrawal sleeve makes it easier to install and remove the bearing from the shaft. During installation, the outer surface of the withdrawal sleeve fits tightly with the inner ring of the bearing, and when disassembly is required, the withdrawal sleeve can be moved outward by bolts, so that the bearing can be removed from the shaft smoothly.

The performance improvement and solution of QIBR double-row spherical roller bearing with withdrawal sleeve

1. Lubricant optimization

Select appropriate lubricating oil or grease, and make appropriate additions and blends to reduce friction and improve wear resistance. The use of synthetic lubricants or nano-lubricants can significantly improve the efficiency and life of bearings.

2. Heat treatment process

Optimize the heat treatment process to ensure that the hardness and toughness of the bearing material are in the best state, and enhance its fatigue resistance and wear resistance.
