Product description Technical parameter
Deep groove ball bearings
Deep groove ball bearings are widely used bearing type and are particularly versatile. They have low friction and are optimized for low noise and low vibration which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than other bearing types. 

The WTOO bearing catalogue lists a large range of designs, variants and sizes of deep groove ball bearings. Beyond our catalogue offering, the WTOO Explorer deep groove ball bearings are customizable to offer advantages for applications with specific performance needs.

How do capped deep groove ball bearings perform under high speed operating conditions?
Capped deep groove ball bearings stand out for their excellent performance characteristics under high-speed operating conditions. One of the key advantages of its cover design is to effectively reduce the friction generated by the bearing during operation, thereby reducing the heat generated by friction. This property is critical to the bearing's performance at high speeds, as heat generated by friction can negatively affect bearing stability and life. Through a carefully designed capping structure, the bearing is able to reduce friction losses when rotating at high speeds, thus improving its efficiency and performance.
The design of the cover can also effectively protect the grease or oil inside the bearing. This means that under high-speed operating conditions, the bearings can always maintain good lubrication and avoid increased friction and wear caused by insufficient or uneven lubrication. Superior lubrication performance is one of the key factors for bearings to operate reliably for a long time in high-speed operating environments.
In addition, the design of the cover is also important to maintain the stability and balance of the bearing. Under high-speed conditions, the forces and torques experienced by bearings may be more complex, easily causing vibration and noise. By using a properly designed capping structure, the bearing can better handle these forces, ensuring smooth operation even at high speeds, improving overall performance and reliability.
Covered deep groove ball bearings pay more attention to the structural rigidity of the bearing in design, and can withstand large radial and axial loads during high-speed operation, ensuring that the bearings still maintain excellent performance under high load conditions. This makes this bearing type the first choice for many high-speed, high-load applications.
Under high-speed operating conditions, bearings often need to face frequent loading and unloading, which poses a challenge to the life of the bearing. The design of the cover helps slow down the occurrence of fatigue wear and improves the fatigue resistance of the bearing, thereby extending its service life.
