R4-2RS chrome steel rings. It can meet the requirements of skateboard. It ensures smooth rotation of the bearing and provides reliable performance under various operating conditions.
The R4-2RS Deep Groove Ball Bearing is a widely - used and highly versatile component in various mechanical and electrical applications. Its compact size yet remarkable performance makes it an essential part in many devices where space is at a premium but reliable operation is crucial.
Features of R4-2RS Deep Groove Ball Bearing
Deep groove ball miniature ball bearings are also widely used in precision instruments due to their high precision, low friction, and excellent stability. These bearings can ensure the accurate rotation and precise movement of various components in precision instruments, helping to improve the measurement accuracy and working efficiency of the instruments, and reducing energy loss and mechanical wear.
Our advantages
The R4-2RS bearing has a low friction coefficient, which can minimize energy loss, ensure smooth operation and improve efficiency. It is small in size but has a strong load-bearing capacity, and can stably withstand radial and axial loads. It also has high-speed capability and can run smoothly at high speeds to meet mechanical needs.
Rings: High-quality chrome steel inner and outer rings ensure stability and durability.
Seals: Double-sided metal dust cover keeps contaminants out.
