Flanged Deep Groove Ball Bearings W 603 R

Flanged Deep Groove Ball Bearings W 603 R

The W 603 R is a compact flanged deep groove ball bearing, measuring just 3mm by 9mm with a 10.5mm flange. Made entirely from stainless steel, it offers good resistance to corrosion and wear.

It handles radial loads up to 73 lbf and can spin at impressive speeds up to 90,000 RPM. The open design allows for easy lubrication when needed.

The flange provides secure mounting, preventing slippage in tight spaces. Its small size and lightweight (only 0.001kg) make it ideal for precision applications.

Suitable for use in small motors, medical devices, or instruments where space is limited. Complies with RoHS and REACH standards for environmental safety.

Interchangeable with SKF bearings, offering flexibility for replacements or upgrades. Works well in temperatures from -30°C to 120°C.
