Stainless Steel Deep Groove Ball Bearings D/W R3A-2RS1

Stainless Steel Deep Groove Ball Bearings D/W R3A-2RS1

The D/W R3A-2RS1 is a compact stainless steel deep groove ball bearing, measuring just 0.18748″ in bore and 0.625″ in outer diameter. Its sealed design keeps grease in and dirt out, making it low-maintenance.

With a dynamic radial load capacity of 192 lbf, it handles moderate loads while spinning smoothly at speeds up to 28,000 RPM. The all-stainless construction resists corrosion and works in temperatures from -30°C to 120°C.

This bearing is interchangeable with SKF models, offering a reliable replacement option. Its small size (0.19598″ wide) and lightweight (0.0049kg) make it ideal for precision instruments or small machinery.

The P0 tolerance and CN radial clearance ensure consistent performance in applications like dental tools or miniature motors where space is limited. Compliant with RoHS and REACH standards for safe use.
