Deep-groove ball bearings resist corrosion

Keywords: Stainless steel, Corrosion resistance, Bearings

A new range of multipurpose stainless-steel deep-groove ball bearings (DGBBs) is resistant to corrosion in moisture and other corrosive environments.

Sealed versions can also be supplied with different grease fillings, which makes them ideal for a wide range of applications, including chemical equipment, paper mills and nuclear technology.

The DGBBs consist of deep raceway grooves, without filling slots, and a close osculation between raceways and balls.

This breakthrough in design means that they can carry axial loads acting in both directions, in addition to radial loads, even at high speeds.The running properties are the same as standard ball bearings although there is a slightly reduced load carrying capacity.

The bearings have been temperature stabilised at 150°C but can withstand temperatures up to 300°C depending on the lubricant used. The ability to use different grease fillings makes the DGBBs highly prized. For example, they can be used in the food industry, which uses non-toxic grease, or industries that require grease with good tolerance levels to high temperatures.

SKF's DGBBs are available in several types and sizes, with diameters up to 50 mm.
