Deep Groove Ball Bearing

1. High Load Capacity: The inner and outer rings of the 6028 deep groove ball bearing have deeper grooves, which improve the stability of the rolling elements and enhance the load-carrying capacity. The structural design of the deep groove can better maintain the position of the rolling elements and prevent the rolling elements from falling off due to eccentricity and improve the load-carrying performance. 

2. Low Friction: The 6028 deep groove ball bearing adopts a high-precision manufacturing process to ensure that the geometry and surface finish of the rolling elements and raceways reach high standards. The smooth surface reduces friction at the contact points and reduces the friction coefficient.

Spherical roller bearing

1.  Self-aligning ability: The outer raceway of the 22207 spherical roller bearing is spherical in shape, which can automatically compensate for the coaxiality deviation caused by installation errors or shaft bending, and is suitable for railway vehicles to work in complex environments. 

2. High load-carrying capacity: It can bear large radial and axial loads, evenly distribute the load in multiple directions, and reduce wear and damage caused by uneven load to ensure the safety and stability of train operation.

Additional Notes:

Spanish customers decided to purchase 22207 spherical roller bearings and 6028 deep groove ball bearings from QIBR company to meet the safety and stability requirements of their railway vehicle axles. Both the 22207 spherical roller bearings and 6028 deep groove ball bearings of QIBR adopt high-quality materials and advanced manufacturing processes to ensure excellent performance even in high-load and high-vibration environments. For railway vehicles, reliability is crucial and safety is improved. The 22207 spherical roller bearing has superior self-aligning ability and can automatically compensate for deviations caused by installation errors or shaft bending. The 6028 deep groove ball bearing has a lower friction coefficient and performs well when the axle is running at high speed, making the railway vehicle run more smoothly during operation.
