Deep groove ball bearings — Versatile for radial and axial loads

Deep groove ball bearings are the most common type of rolling bearings. Deep groove ball bearings are composed of an outer ring, an inner ring, a set of steel balls, and cages. There are two types of deep groove ball bearings, single row and double row. The deep groove ball structure is also divided into two types: sealed and open. The open type refers to the bearing without a sealed structure.

TFL as a leading bearing manufacturer and supplier in China, We can provide various types of deep groove ball bearings, imperial thrust ball bearings, and bearing sizes support metric and inch.
Various sizes can also be customized according to customers’ needs for bearings. If necessary, please email me.

Further Information


Deep groove ball bearings are the most widely used bearing types, prevalent use. They have low friction and are optimized for low noise and low vibration, thereby realizing a high speed. They are subjected to two directions of radial and axial loads, are easy to install, and require less maintenance than other types of bearings.

They are divided into two designs: Single-row deep groove ball bearings and double row bearings with two ball bearings. They may also be made in different sizes depending on the application and the different loads, miniature ball bearings from a light load to large and small components of deep groove ball bearings and deep groove bearing heavy loads.

TFL Bearings has a huge selection of the best deep groove ball bearings and Instrument Series Ball Bearings with over 500 types available. Precision tolerances from ABEC-1 through ABEC-9 are generally available for most miniature products. Typical bore sizes of miniature ball bearings start at 3 mm with an outside diameter of 10 mm. Custom-made miniature bearings can have borne sizes as small as 1 mm!

Versions of deep groove ball bearings

  • Single row Main dimensions according to DIN 625-1. Favorable “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 a 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, offers high load-ratings, is magnetic, and is 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
    They are subject to lesser wear and tear compared to bearings of similar size with steel balls. The ceramic balls are currently 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
    They 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, are suitable for a dry run, are current insulating, non-magnetic, and operate up to a temperature of circa +160°C. The balls’ ceramic material and the rings are temperature-resistant up to circa +800°C, the cage-material up to +160°C.
