Cuscinetti radiali a sfere
Deep groove ball bearings are the most common type of rolling bearing. Deep groove ball bearings consist of an outer ring, un anello interiore, a set of steel balls and a cage. Deep groove ball bearings are available in single row and double row. Deep groove ball structure is also divided into sealed and open type. Open type refers to bearings without a sealed structure.
As a leading bearing manufacturer and supplier in China, we can provide various types of deep groove ball bearings, imperial thrust ball bearings, as well as support metric and imperial bearing sizes.
Various sizes can also be customised according to the customer’s requirements for the bearings. If required, please email me.

Product types, designs and variants
Single Row Deep Groove Ball Bearing
single deep groove ball bearings
are the most widely used roller bearing type in the world due to their versatility and comprehensive performance. They are characterised by having deep raceway grooves and the radius of the inner and outer ring arcs is slightly larger than the radius of the ball. They also have non-separable rings. Their straightforward basic design offers a number of advantages.
- Very suitable for high speeds
- Good radial load capacity
- Acceptable axial load capacity in both directions
- Low torque capacity at start-up and running speeds
- Can be operated with low noise
- Little maintenance required
Double row deep groove ball bearing
In terms of design, double row deep groove ball bearings are similar to ball bearing single row deep groove. Their deep, complete raceway grooves are tightly integrated with the balls, enabling the bearings to withstand radial and axial stresses. These ball bearings are ideal for bearing systems when the load carrying capacity of a single row bearing is insufficient. The deep groove double row ball bearing
in the 62 e 63 series are somewhat wider than the single row bearings in the same bore. Two-row deep groove ball bearings can only be used as open type bearings.
Stainless steel deep groove ball bearings
Stainless steel deep groove ball bearings have a higher chemical and corrosion resistance. Like the usual deep groove ball bearings, they are particularly versatile, have low friction and are optimised for low noise and vibration, enabling high speeds to be achieved. They can withstand radial and axial loads in both directions, are easy to mount and require less maintenance than many other types of bearing.
- Greater chemical and corrosion resistance
- Simple, versatile and robust design
- Low friction and high speed capability
- Withstands radial and axial loads in both directions
- Requires little maintenance
Miniature deep groove ball bearings
Single row deep groove ball bearings with a ball filling groove have a ball filling groove on both the inner and outer rings, which can accommodate more balls than standard deep groove ball bearings.
Filled slot bearings have a higher radial load carrying capacity than bearings without filled slots, but their axial load carrying capacity is limited. They also cannot operate at the same high speeds as bearings without filled slots.
Deep groove ball bearings with filled slots are available open or with dust caps on one or both sides. They can also be supplied with or without snap ring grooves. Open type bearings with dust caps may also be supplied with recesses in the outer ring.
We can supply large size deep groove ball bearings with ball filling slots without cages on request.
Characteristics of deep groove ball bearings
Easy interchangeability
Our deep groove bearings are designed as metric bearings, conform to ISO standards and are dimensionally interchangeable with our competitors’ metric products.
Brass cage availability
Deep groove ball bearings with brass cages (available in selected sizes) provide extra strength and durability under the harshest conditions: extreme shock loads, high vibration and high forces from acceleration.
Motor quality for quiet running
Deep groove ball bearings are often used in electric motor applications to minimise vibration and noise. To meet our long-established motor quality guidelines, we have designed.
- Superfinishing of the raceways to reduce friction
- Preferred clearance markings (C3)
- High-performance, low-torque and low-noise premium grease

FAQ
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!

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.
