Flanged Deep Groove Ball Bearings D/W R4 R

Flanged Deep Groove Ball Bearings D/W R4 R

The D/W R4 R is a compact flanged deep groove ball bearing, measuring 0.25″ in bore and 0.625″ in outer diameter, with a flange extending to 0.69″. Made entirely from stainless steel, it offers good resistance to corrosion and wear.

It handles radial loads up to 192 lbf and can spin at speeds up to 60,000 RPM, making it suitable for high-speed applications. The open design allows for easy lubrication if needed.

The flange provides extra stability, helping to keep the bearing securely in place during operation. Its lightweight design, at just 0.0042 kg, makes it easy to handle and install.

Ideal for small machinery or instruments where space is limited but performance is key. Compliant with RoHS and REACH standards, ensuring safe and environmentally friendly use.
