Flanged Deep Groove Ball Bearings D/W R144 R

Flanged Deep Groove Ball Bearings D/W R144 R

The D/W R144 R is a compact flanged deep groove ball bearing, measuring just 0.125″ in bore diameter and 0.25″ in outer diameter. Made entirely from stainless steel, it offers good resistance to corrosion and wear.

This bearing handles radial loads up to 37 lbf and can spin at impressive speeds of up to 100,000 RPM. Its open design allows for easy lubrication when needed.

The flange provides secure mounting, helping the bearing stay in place during operation. With a temperature range of -30°C to 120°C, it’s suitable for various environments.

Ideal for small precision instruments or dental tools where space is limited. Compliant with RoHS and REACH standards, it’s a reliable choice for sensitive applications.

Weighing only 0.0003kg, it’s remarkably lightweight yet durable for its tiny size. The bearing is interchangeable with SKF models for easy replacement.
