Double row Spherical roller bearing with an adapter sleeve

The spherical roller bearing with adapter sleeve is composed of an inner ring, an outer ring, rollers and an adjusting ring. There are some tapered holes on the adjusting ring with adapter sleeve, which are used together with the locking nut. By rotating the locking nut counterclockwise, the clearance inside the roller bearing can be reduced, thereby achieving the purpose of tightening the bearing.

The design of the double-row spherical roller bearing with adapter sleeve simplifies the installation and removal process. The tapered bore bearing can be easily installed and removed on the shaft by using fasteners or withdrawal sleeves, which is very beneficial for maintenance and replacement.

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

QIBR double-row spherical roller bearings with adapter 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 adapter 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 adapter 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 adapter sleeves have strong adaptability and can adapt to large axial offsets and radial load changes.

4. Easy to install

Compared with other types of roller bearings, double-row spherical roller bearings with adapter sleeves use adapter sleeves to prevent the bearings from loosening or slipping during operation. The adapter sleeve fixes the bearing to the shaft with bolts, usually with an internal hexagon or external hexagon design, which is easy to disassemble and install.

The performance improvement and solution of QIBR double-row spherical roller bearing with adapter 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.

3. Improve the quality of rolling elements
