Cuscinetti radiali a sfere

Deep groove ball bearings are the most widely used type of bearing and are commonly used. They have low friction and are optimised for low noise and low vibration, resulting in high speeds. They carry radial and axial loads in both directions, are easy to mount and require less maintenance than other types of bearing.

They are available in two designs: single-row deep groove ball bearings and double-row bearings with two ball bearings. They can also be made in different sizes depending on the application and the different loads, from miniature ball bearings for light loads to large and small assemblies of deep groove ball bearings and deep groove ball bearings for heavy loads.

Deruna Bearings offers a wide range of the best deep groove ball bearings and the Instrument range of ball bearings, with over 500 types to choose from. Precision tolerances from ABEC-1 to ABEC-9 are typically available for most miniature products. Typical bore diameters for miniature ball bearings start at 3 mm and have an outside diameter of 10 mm. Customised miniature bearings are available with bearing sizes as small as 1 mm!

Versions of deep groove ball bearings

• Fila unica of main dimensions in accordance with DIN 625-1. Beneficial “all-round bearing”. Versatile.
• Double row main dimensions in accordance with DIN 625-3. Much higher load carrying capacity than single row bearings, slightly wider.
• Deep groove ball bearings with flanged outer ring
  Simplified locating bore for axial fixing of the bearing.
• With groove and snap ring
  Suitable for shape-fitting axial fixing of bearings in bores.
• Full ball set
  Without cage and maximum number of balls, with a higher load carrying capacity than deep groove ball bearings with cage of the same size.

Deep groove ball bearing material description

• Ball bearings made of rolling bearing steel
  are extremely economical, can withstand high load ratings and are suitable for temperatures from approx. -10°C to +120°C, if rubber seals are used for long periods up to approx. +100°C. Rolling bearing steel is wear-resistant, vibration-resistant, electrically conductive and magnetic.
• Stainless steel ball bearings
  Hygienic, corrosion-resistant, lubricated mainly with grease for the food industry, provide high load ratings, are magnetic and can be used in the temperature range from approx. -20°C to +120°C in the case of rubber seals Up to +120°C in the long term
• Hybrid bearings with ceramic balls and ceramic rings made of stainless steel or rolling bearing steel
  They are subject to less wear and tear than steel ball bearings of similar dimensions. Ceramic balls are currently insulated. Hybrid bearings are lighter than steel ball bearings of the same size, can withstand higher speeds and operate in a temperature range of approx. -20°C to +130°C if the rubber seals are up to approx. +100°C in the long term. Hybrid bearings are magnetic.
• Ball bearings made of ceramic
  They are hard, corrosion-resistant and durable, and therefore very wear-resistant. They have good emergency running characteristics, are lighter than steel bearings of the same size, are suitable for dry running, are current-insulated, non-magnetic and can be operated at temperatures up to around +160°C. The ceramic material of the balls and the rings are heat-resistant up to approx. +800°C and the cage material up to +160°C.

DGBB can withstand axial loads in two directions, while angular contact ball bearings can only withstand axial loads in one direction.

Seals and shields provide additional protection for the bearing components and help to improve and maintain lubrication. In terms of sealing performance, sealed bearings rank best, followed by shielded bearings and finally open bearings. NSK uses supplementary designations D, DU, DW and V (DD, DDU, DDW, VV) for sealed bearings and Z (ZZ) for shielded bearings. No supplementary designations are added for open bearings.
