Standard single row Spherical roller bearing

‌Single-row spherical roller bearings‌ are widely used in various mechanical equipment due to their unique self-aligning ability and ability to withstand radial and axial loads. The design of this bearing allows slight misalignment of the shaft or housing, thereby reducing mechanical damage caused by installation errors or vibration during operation. In addition, single-row spherical roller bearings also have good lubrication properties, usually do not require maintenance, and are suitable for high-speed operation environments.

Single-row spherical roller bearings have a wide range of applications, including motors, reducers, power tools, air conditioners, automotive gearboxes, agricultural machinery, textile machinery, food industry and other fields.

Features and advantages of QIBR single-row standard spherical roller bearings

QIBR single-row standard spherical roller bearings solve multiple key problems in various fields, mainly reflected in the following aspects:

1. Self-aligning ability

The raceways of the inner and outer rings of single-row spherical roller bearings 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 installation errors.

2. Strong load-bearing capacity

The rollers of spherical roller bearings are cylindrical or slightly inclined, with a large contact surface, and can withstand large radial loads. Due to the large number of rollers, they have a higher load-bearing capacity, especially in high-load and high-impact application scenarios.

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 harsh working conditions.

4. Easy to install

Compared with other types of roller bearings, single-row spherical roller bearings can simplify installation requirements and reduce the risk of bearing failures due to installation errors due to their self-aligning function.

The performance improvement and solutions of QIBR single-row standard spherical roller bearing

1. Lubricant optimization

Select appropriate lubricating oil or grease, and make appropriate additions and blends to reduce friction and improve wear resistance. Using 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

Reduce friction and wear by improving the surface finish and hardness of the rolling elements. Using high-precision rolling elements (such as ceramics) can significantly improve the operating performance of the bearing.

4. Cage design optimization

Use a more optimized cage structure, such as using high-temperature and corrosion-resistant materials and designs to improve the durability of the cage and the stability of the bearing.

Main application areas of QIBR single-row standard spherical roller bearings

1.Mining machinery

Such as crushers, conveyors, ball mills and other equipment, due to their harsh working environment and heavy loads, single-row spherical roller bearings can provide high load bearing capacity and avoid failures caused by installation errors.

2.Metallurgical equipment

Such as rolling mill equipment and roller tables in steel plants, single-row spherical roller bearings can effectively withstand heavy loads and impacts generated in metallurgical production.

3.Hydro power generator sets

Bearings of large power equipment such as turbines and generators. Since power equipment needs to bear a large amount of load and long-term operation, single-row spherical roller bearings have good self-alignment and are suitable for this type of equipment.

4.Shipbuilding industry

Single-row spherical roller bearings are often used in key parts of ships due to their excellent load-bearing capacity and durability in the rudder shaft, transmission shaft and other parts of ships.
