Essential deep groove ball bearing parameters
The most popular kind of rolling bearings are deep groove ball bearings. An outer ring, an inner ring, a set of steel balls, and a set of cages make up a basic deep groove ball bearing. Deep groove ball bearings come in two varieties: single-row and double-row. There are two varieties of deep groove ball structures: sealed and open. and seals that are oil-proof. The steel plate imprinted on the cover material of the sealed and dust-proof deep groove ball serves merely to keep dust out of the bearing raceway.
As a contact oil seal, the oil-proof deep groove ball bearing can successfully stop the grease in the bearing from spilling out. Two codes are assigned to deep groove ball bearings: 6 for a single row and 4 for a double row. It is the most extensively used and well-liked bearing due to its easy usage and straightforward construction.
The deep groove ball bearings’ functioning
In addition to being able to support both radial and axial loads simultaneously, deep groove ball bearings primarily support radial loads. The contact angle is zero when only radial loads are applied to it. A deep groove ball bearing functions like an angular contact bearing and can support a significant axial load when it has enough radial clearance. The deep groove ball bearing has a high maximum speed and a minimal coefficient of friction.
Characteristics of ball bearings with deep grooves
The most widely used rolling bearings are deep groove ball bearings. It has an easy-to-use, straightforward framework. Its primary function is to support radial loads; however, if the bearing’s radial clearance is increased, it may also support combined axial and radial loads due to its absolute angular contact ball bearing performance. In situations when a thrust ball bearing is not appropriate due to high speed, it can also be utilized to support pure axial loads.
Deep groove ball bearings are a type of bearing that has a minimal friction coefficient and a high limiting speed when compared to other bearing types that meet the same parameters. However, it cannot withstand impact and is not appropriate for large weights.
The axial displacement of the rod or housing can be restricted in the axial clearance of the deep groove ball bearing once it is mounted on the shaft, allowing it to be axially positioned in both directions. Furthermore, this kind of bearing possesses a particular capacity to self-align. It can generally still function when inclined 2′ to 10′ concerning the housing hole, but the bearing life is significantly affected.
Deep groove ball bearing structure
Deep groove ball bearings are widely used, inexpensive to produce, and easy to attain greater manufacturing precision than other varieties. Their straightforward design makes them suitable for mass production in series. Deep groove ball bearings come in a variety of modified structures in addition to the basic model, including dust cover, rubber seal, retaining groove, ball notch, large load capacity, and double row deep groove ball bearing.
Deep groove ball bearings: benefits
Deep groove ball bearings don’t require regular maintenance and can be utilized in high- and very-speed applications. These bearing varieties are not only adaptable but also have several advantages, such as:

3. Minimal need for upkeep or servicing
Unlike other bearing types, deep groove ball bearings have a prolonged shelf life due to their low friction, simple construction, and lowered operating temperature. There will be reduced maintenance downtime because they don’t require further lubrication or greasing after installation.
4. Silent functioning
Ball bearings with deep grooves are designed to minimize noise and vibration while reducing friction. They provide outstanding performance with a guaranteed quieter operation.
Deep Groove Ball Bearing Types
Deep Groove Ball Bearings with Single-row
Deep groove ball bearings, which come with a single raceway, have a longer service life since they are robust and composed of long-lasting materials. Single-row deep groove ball bearings, available in diameters ranging from 3 mm to 400 mm, are a versatile option that may be utilized in many applications.
Deep Groove Ball Bearings with Double Rows
These bearing types are meant for applications that require a larger load-carrying capacity while maintaining low friction because of their double-row construction. These bearings are more useful and adaptable than single-row bearings because they are somewhat broader.
Deep groove ball bearing features
They are sturdy in operation, easy to maintain, and have a basic design with a wide dimensional scope.
High rotating speed: For superior performance in demanding applications with heavy loads and high rotational speeds, deep groove ball bearings are composed of premium steel.
Able to withstand both radial and bidirectional axial load: Deep groove ball bearings can withstand both radial and bidirectional axial forces. They were able to support heavier weights and were adaptable enough to be utilized in a variety of settings.

Installing deep groove ball bearings
Approach 1: Press-fit
Both the shaft and the bearing’s inner ring are firmly fitted. A press can be used to force the bearing onto the pole once the outer ring and bearing seat hole have been loosely fitted. Next, the shaft and bearing are put into the bearing seat hole. There is a soft metal material assembly sleeve (made of mild steel or copper) that cushions the end face of the bearing inner ring. The bearing seat hole is securely fitted with the outer bearing ring. The bearing can be forced into the bearing initially when the shaft and inner circle are loosely fitting.
The mounting sleeve’s outside diameter in the seat hole has to be somewhat less than the hole’s width. The inner and outer rings must be forced into the shaft and the seat hole simultaneously if the bearing ring is to be snugly fitted with the shaft and the hole. The mounting sleeve’s construction should be able to simultaneously tighten the outer and inner rings of the bearings.
2. Heat-based
Thermal expansion is utilized to change a tight fit into a loose fit by heating the bearing or bearing seat. It is a popular and time-saving installation technique. Bearings with a high interference quantity can be installed using this approach. The detachable bearing’s ferrule is inserted into the oil tank and uniformly heated to 80 to 100 °C. It is then removed from the oil and quickly mounted on the shaft.
axial compression. A hot mounting method with a heated bearing seat can be utilized to avoid scratches on the mating surface when the outer bearing ring is firmly matched with a light metal bearing seat.
A grid should be positioned at a specific distance from the oil tank’s bottom for heating the bearing, or the bearing can be suspended using a hook. To avoid contaminants getting inside the bearing or uneven heating, the bearing cannot be positioned on the bottom of the tank. A thermometer has to be present in the tank. To stop the tempering effect and lessen the ferrule’s hardness, strictly regulate the oil temperature so that it does not rise over 100 °C.
