In the precision world of bearings, the cage is not obvious, but it is a key component that determines the performance of bearings. This seemingly simple component performs the important function of isolating the rolling element, guiding the movement, and distributing lubrication.
The quality of cage directly affects the overall performance of bearing. A high-quality cage can effectively reduce the friction coefficient of bearings, reduce energy loss, and improve operating efficiency. It also ensures the uniform distribution of the rolling element and prevents biased load, thus extending the service life of the bearing. Under high-speed operating conditions, the stability of the cage determines whether the bearing can work normally.
High quality cages must meet stringent technical requirements. Material selection, need to have excellent mechanical strength and wear resistance, but also consider corrosion resistance and self-lubrication properties. Machining accuracy is the key, the dimensional tolerance is usually controlled in the micron level, the surface roughness to achieve the mirror effect. These technical requirements directly determine the running accuracy and service life of the bearing.
ZWA understands that the bearing cage is the core component to ensure bearing performance, and its quality directly determines the overall reliability of the bearing.
As a result, ZWA uses cages designed with high precision and manufactured with advanced technology to accurately separate rolling elements and maintain uniform load distribution.
In this way, the bearing can be endowed with excellent operating stability and durability, and become a reliable guarantee for high-end mechanical equipment.

One of the most critical components is the bearing cage, When the rolling bearing is working, especially when the load is complex and the rotating speed is high, the cage has to withstand great centrifugal force, impact and vibration, and there is a large sliding friction between the cage and the rolling body, and generate a lot of heat.
By combining high-end technology with the best materials, ZWA provides customers with the highest quality steel and brass bearing cage, improving the quality and the service life of roller bearings.
