Deep groove ball bearings are versatile, self-retaining bearings with solid outer rings, inner rings and ball and cage assemblies. These bearings with their simple design, high resistance and low-maintenance, are available in single-row and double-row designs, as well as sealed and unsealed. Due to the manufacturing processes used, open bearings can have turned recesses in the outer ring for seals or shields.
Axial deep groove ball bearings comprise shaft locating washers, housing locating washers and ball and cage assemblies. The bearings are not self-retaining; the ball and cage assembly and bearing washers can therefore be fitted separately. In addition to the series with flat washers, series are also available with spherical housing locating washers for the compensation of static angular misalignment. These designs are normally used in conjunction with seating washers.
Deep groove ball bearings of generation C were specially developed in relation to low noise levels and low frictional torque. They are particularly suitable, for example, for use in electrical machinery, ventilators, washing machines and power tools. Design changes such as improved bearing kinematics, new seals and cages, as well as a refined manufacturing process generate several benefits for the generation C deep groove ball bearings.

They are commonly used in electric motors and in household appliances, car motors, office machinery, automation control, and garden and household tools. They have deep raceway grooves and their race dimensions are close to the dimensions of the balls that run inside.
Deep groove ball bearings come in many sizes, materials and varieties according to consumer needs, including special industrial uses such as high-temperature applications. High-temperature bearings are made to withstand temperatures up to 350C (660F) and are suitable for machines used in the metals industry or for industrial ovens.
They fall under two designs: there are single-row deep groove ball bearings with a single row ; and there are double-row bearings, which have two rows of bearing balls. They can also be made in different sizes and for different loads according to their application, from miniature ball bearings for light loads and small assemblies to large deep groove ball bearings and heavy load deep groove bearings.
Replacing deep groove ball bearings with plain bearings can offer a range of benefits, including lower cost, less maintenance, greatly reduce noise at low speeds and easier installation. Plain bearing can also have a higher load capacity, simplified assembly, increased longevity, reduced housing dimensions and assembly size and weight.
Deep groove ball bearings are suitable for moderate radial or thrust loads and combined radial/thrust loads. The metric DGB series follows ISO design practices for boundary dimensions, Bore, O.D., width and corner radii. Both metric and inch series bearings are supplied with a two-piece machined brass cage, ball centered in most sizes and land riding in the very large bearings. Unless otherwise specified by the end-user, these extra large ball bearings will automatically be supplied with a C3 clearance for metric bearings and B3 for inch series ball bearings. This is necessary to provide some mounted clearance since these bearings are typically mounted on a shaft with an interference fit.
These deep groove radial ball bearings are suitable for low and heavy radial loads. The 6000 series can accommodate low to moderate thrust loads in either loading direction.
We stock bearings for practically any running precision requirement and application speed: our bearings come in Abec tolerance grades 1-9, internal clearances from C2 to C4, and several different cage designs including J-type, W-type, RJ-type, TW-type, and more.
Deep groove bearings have race dimensions that are similar to their ball dimensions. These bearings can be used in a wide variety of applications. They have grooved raceways on the inner and outer rings allowing them to sustain moderate radial and axial loads in both directions. They are well suited to high speed applications and can maintain their precision tolerance during high speed operation. Click above to see our selection of deep groove bearings with inch dimensions.

Deep Notch, sometimes West Kill Notch,[1] or Echo Notch,[2] is a mountain pass in Lexington, New York, United States. It divides two Catskill peaks, both subpeaks of high peaks of the range. The narrow groove between the steep, high slopes on either side is traversed by state highway NY 42 and the Shandaken Tunnel, part of the New York City water supply system. It has been called "striking"[3] and "a marvel of grandeur and beauty".[4]
The crystal structure of a complex of spermine with the DNA octamer d(GTGTACAC) has been determined at 2.0-A resolution. The alternating sequence adopts an A-DNA conformation with a novel purine-purine extra-Watson-Crick hydrogen bond involving the central guanine G3 (G11) and adenine A13 (A5) in the deep groove. The oligocation spermine binds in the floor of the deep groove by interacting with the bases and assumes an S-shape. Its dyad is coincident with that of the DNA, reminiscent of repressor binding to B-DNA. The terminal and central ammonium groups of the top half of spermine form hydrogen-bonding interactions to the 5'-bases, GTG, of one strand; then the spermine winds across the groove to interact with the corresponding set of bases on the other strand. The methylene groups of spermine form a hydrophobic cluster with the methyl groups of the thymines and the O6 atoms of the guanines of the TGT sequences on either side of the dyad. The observed mode of binding of spermine to A-DNA can serve as a model for deep groove binding in RNA and DNA-RNA hybrids that show a propensity also for the A-conformation. It will be of interest to see if base binding of spermine to DNA is involved in the regulation of gene expression, since spermine and other oligocations are ubiquitous in cells and their concentration is coupled to stages in cell cycle.
These characteristics match our high-precision radial deep groove ball bearings perfectly! This type of ball bearing is self-retaining and operates both at low and high speeds. They can be used in various applications, for example in machine design for excavators and cranes.
Our high precision miniature radial deep groove ball bearings are very efficient and designed to take in radial as well as, to a lesser extent, an axial load. While radial forces act perpendicularly to the shaft axis, axial forces pass along the axis of the shaft or body.
The radial deep groove ball bearings made by GRW are single row radial ball bearings. They are available in open as well as sealed or shielded versions. They are composed of the following parts and materials:
Classification of radial deep groove ball bearings in the standard-versions is secured by DIN/ISO or ANSI/ABMA norms. As always, we offer you the possibility to buy individualized ball bearings. We are looking forward to your request.
This paper deals with detection of local defects existing on races of deep groove ball bearing in the presence of external vibrations using envelope analysis and Duffing oscillator. Experiments have been carried out using a test rig for capturing the vibration signals of test bearing. The external vibration has been imparted to the housing of the test bearing through electromechanical shaker. In envelope analysis the centre frequency has been selected using the spectral kurtosis for the filters length of 32 and 64 for different bandwidths. Through this study, it has been revisited and confirmed that the defect detection in envelope analysis mainly depends on the selection of centre frequency and bandwidth. The spectra of selected centre frequency with several bandwidths have been studied and compared for identification of defective frequency. The system defined by the Duffing equation entered into the periodical state from the chaotic state at the critical value of disturbing periodic force in the presence of defective bearing signal. The state change has been identified using the phase plane trajectories and Lyapunov exponents of Duffing equation. It is worth to mention here that envelope spectrum reveals the information about the defect frequencies and their harmonics. However, the Duffing oscillator only confirms the presence of defect frequencies by indicating closed phase plane trajectories and negative Lyapunov exponents. Authors believe that for speedy assessment about the presence of defects on races of rolling element bearings, the use of Duffing oscillator may be preferred.
