what are Deep Groove Ball Bearings？

The ring and outer ring and spherical balls and cage structure. The deep raceway grooves of Deep Gro preferred choice for various mechanical applications. The Deep Groove Ball Bearing exists in two configurations which include single large industrial machinery parts. The Deep Groove Ball Bearing meets various operational requirements through its selection of seals and materials which enable it to operate at high speeds and handle heavy loads and harsh environments. The single. The bearing achieves excellent rotational speed performance and low friction levels of friction which makes it suitable for applications that experience radial forces and combined radial-axial loads and axial-only loads. The main function of together. The contact angle becomes zero when the bearing operates under pure radial loading conditions. The bearing operates Deep Groove Ball Bearing offers low friction performance and high speed operation which helps solve industrial problems by providing

Features of Deep Groove Ball Bearings

Deep Groove ball bearings are the most popular of all the ball bearing types and there are single row deep groove ball bearings and double row deep groove ball bearings types.because they are available in a wide variety of seal, shield and snap-ring arrangements. Designed around a basic geometry, this bearing minimizes friction and is the most common type.Amazingly, even after more than 100 years of use, this bearing is the most widely used push against sliding motion with a rolling motion.

Compact and Robust Geometry：The deep uninterrupted raceway grooves are packed with balls enabling this bearing to accommodate thrust, as well as radial load and combined loads. These grooves are dimensioned closer to the ball diameter to maintain 100% contact under as little as.005” of misalignment or end-float. The geometry generates low contact stress that gives way to low friction and a smooth rotation.

Versatile Load Capacity：It can also be a radial load to bear, more when increasing the radial clearance of the bearing, used as a axial bearing. Through increasing radial internal clearance, or by using a combination of radial and axial fits, it can also operate angular-contact-like in combined-radial-and-axial applications so it is a versatile option for most shaft-support requirements.

High-Speed and Low-Noise Operation：Because of the small particle size and evenly control distribution,high limit speeds could be achieve through lower vibration sound and service life factors. These qualities make it an excellent choice for use in electric motors, precision instruments, fans and in other applications where the avoidance of dissipated power is desired.

Ease of Installation and Low Maintenance：Due to tolerances within DGBB the bearing unit can be mounted with an interference fit. Most of NTN Tapered roller bearings are separated type, that means bearing assembly with roller and cage, the seal or shield can be installed on both side without the inner ring there will be small space between rollers and cage which minimum the contact surface.

Thermal and Misalignment Tolerance：Some types of Deep Groove Ball Bearing can sustain high temperature allowing the usage of in high temperature environment—also they resist to a certain amount of angular misalignment between the shaft and housing (few minutes of arc). That said, too much misalignment, or any amount of shock loading can reduce life and should be optimized.

We can solve your problems

Reduce maintenance costs：Extend equipment service intervals by using durable, high-performance bearing solutions that minimize wear and lower the need for frequent replacements.

Frequently Asked Questions

Find answers to common questions about our bearings. If you don’t find what you’re looking for, please don’t hesitate to contact us.

What is meant by radial versus axial loading?

Loads which are normal to the axis of the shaft are called radial loads as they push or pull from the bearing with respect to the center line of the shaft. Conversely axial loads are forces (parallel to the shaft like pushing it) acting in the same direction parallel to the axis, and these are both typically referred as thrust loads.

In what ways do deep-groove ball bearings differ from single-row angular contact ball bearings?

Deep-groove bearings support lateral loads along their faces because of the raceway geometry, but they also do fairly well under a small amount of axial load. In contrast, a single-row angular contact ball bearing is designed to accommodate axial load in only one direction (bearing whose faces the seal) and it accommodates pure axial load and operate under higher speeds. This axial force capacity and their pre-loadable design make these bearings ideal for use in applications where there are similar high demands on axial control and high speed performance.

How do open, sealed, and shielded deep-groove ball bearings differ?

The primary distinction lies in how they protect internal components from contaminants and retain lubricant:

Open bearings have no seals or shields, offering the least protection. They allow free ingress of contaminants and lubricant escape, but they exhibit minimal friction and heat rise—making them suitable for clean, controlled environments.
Shielded bearings include one or two non-contact metal shields (often designated Z or ZZ) that block larger particles while imposing only a minor drag. They provide moderate protection and are ideal when light shielding suffices.
Sealed bearings feature contact or non-contact elastomer seals (e.g., D, DU, DW, V, DD, DDU) that tightly protect against dirt and retain lubricant within. While offering the highest level of sealing, they cause higher torque and slightly reduce speed limits due to seal drag.

Manufacturers (for example NSK) use suffix letters—like D / DD / DU / DDU / DW / DDW / V / VV—to denote various sealed bearing configurations, whereas shielded variants may carry Z / ZZ designations. Open bearings carry no such suffix. Some advanced designs also integrate labyrinth seals or multi-lip arrangements to balance protection with low-friction performance.

Why are deep groove ball bearings suitable for both radial and axial loads?

Deep groove ball bearings feature curved raceways nearly matching the ball size. Because of this shape, they handle radial forces well, yet can manage some thrust loads either way.The ongoing raceway touch spreads weight better, so it runs smooth even when moving fast.

Why do deep groove ball bearings sometimes fail earlier than expected?

Premature breakdowns usually come from mistakes during setup, dirty parts, wrong grease use, or poor gap choice not because the bearing’s made badly.Misalignment or too much preload might slash bearing lifespan especially if the grease isn’t right even when loads are light.
