Deep groove ball bearings — Versatile for radial and axial loads

Deep groove ball bearings are the most widely used rolling bearings. Easy to set up, self-holding and insensitive to maintenance. Deep groove ball bearings are available in a multitude of sizes and designs.

Versions of deep groove ball bearings

Single row: Main dimensions according to DIN 625-1. Favourable "all-round bearing". Versatile.
Double row: Main dimensions according to DIN 625-3. Considerably higher load carrying capacity than single row bearings at a slightly greater width.
Deep groove ball bearings with a flanged outer ring: For simplified locating bores in which the bearing is supposed to be axially fixed.
With slot and snap ring: Suitable for the form-fitting axial fixing of the bearing in a bore.
Full complement ball set: Without a cage and maximum number of balls, higher load carrying capacity than caged deep groove ball bearings of the same size.

Material description of deep groove ball bearings

Ball bearings made of rolling bearing steel: Extremely economical, withstand high load-ratings and are suitable for temperatures from circa -10°C up to +120°C, in case of rubber seals up to circa +100°C in the long run. The rolling bearing steel is wear-resistant, shock-resistant, conductive and magnetic.
Ball bearings made of stainless steel: are hygienic, corrosion-resistant, mostly lubricated with grease for the food industry, offer high load-ratings, magnetic and are admissible for a temperature range from circa -20°C up to +120°C, in case of rubber seals up to +120°C in the long run.
Hybrid bearings with ceramic balls and rings made of stainless steel or rolling bearing steel: are subject to a lesser wear and tear compared to bearings of similar size with steel balls. The ceramic balls are current insulating. Hybrid bearings are lighter than bearings with steel balls of the same size, withstand higher speeds and operate in a temperature range from circa -20°C up to +130°C, in case of rubber seals up to circa +100°C in the long run. Hybrid bearings are magnetic.
Ball bearings made of ceramic: are extremely wear-resistant by their great hardness, corrosion-resistant and durable. They have good emergency running characteristics, are lighter than steel bearings of the same size, suitable for dry run, current insulating, non-magnetic and operate up to a temperature of circa +250°C. The ceramic-material of the balls and the rings is temperature-resistant up to circa +800°C, the cage-material up to +250°C.
