Stainless Steel Deep Groove Ball Bearings D/W R3A

Stainless Steel Deep Groove Ball Bearings D/W R3A

The D/W R3A is a compact stainless steel deep groove ball bearing, measuring just 0.18748″ in bore diameter and 0.625″ in outer diameter. Its single-row design and open seal make it simple to maintain, while the all-stainless construction ensures corrosion resistance.

It handles radial loads up to 192 lbf and spins smoothly at speeds up to 56,000 RPM, suitable for high-speed applications. The bearing operates reliably in temperatures ranging from -30°C to 120°C.

With a lightweight design at only 0.0044kg, it’s easy to handle and install. The P0 tolerance class and CN radial clearance provide consistent performance for precision needs.

This model is interchangeable with SKF bearings, making it a practical choice for replacements. Ideal for small machinery, medical devices, or instruments where durability and hygiene matter. Compliant with RoHS and REACH standards for safe use.
