Stainless Steel Deep Groove Ball Bearings D/W R4A-2RS1

Stainless Steel Deep Groove Ball Bearings D/W R4A-2RS1

The D/W R4A-2RS1 is a compact stainless steel deep groove ball bearing, measuring 0.25″ by 0.75″ by 0.28118″. Its sealed design keeps grease in and dirt out, making it low-maintenance.

It handles radial loads up to 344 lbf and spins smoothly at speeds up to 24,000 RPM. The all-stainless construction resists corrosion and works in temperatures from -30°C to 120°C.

This bearing is interchangeable with SKF models, ideal for replacements in small machinery. Its small size (just 0.009kg) suits precision tools or medical devices where cleanliness matters.

Compliant with RoHS and REACH standards, it’s a reliable choice for harsh environments. The sealed design also makes it suitable for food processing or marine applications.
