- The standard double-row deep groove ball bearings are type 4200A, 4300A
- Deep groove ball bearings or single row radial ball bearings are the most widely used bearings in all general industries.
They use uninterrupted raceways to make them most suitable for bearing radial loads. Radial ball bearings are usually equipped with a pressed steel cage, but machined brass or molded nylon materials can also be used. Bearings with locating snap rings on the outer diameter are also available. - Bearing types are divided into single row deep groove ball bearings, double row deep groove ball bearings, thrust deep groove ball bearings, centripetal deep groove ball bearings, stainless steel deep groove ball bearings, deep groove ball bearing pullers, and outer ring grooved bearings. Flange deep groove ball bearings, 6001rs ceramic bearings, deep groove ball bearings, slotted ball bearings, high-speed deep groove ball bearings, deep groove thrust ball bearings, sealed deep groove ball bearings, miniature deep groove ball bearings, inch deep groove ball bearings , Hybrid deep groove ball bearings, grooved roller bearings, V-groove deep groove ball bearings, China U-groove roller bearings.
- They are commonly used in electric motors and household appliances, automotive motors, office machinery, automation control, and gardening and household tools. They have deep raceway grooves, and their raceway size is close to the size of the ball running inside.
- Deep groove ball bearings are available in a variety of sizes, materials and varieties according to the needs of consumers, including special industrial uses such as high-temperature applications. High-temperature bearings can withstand temperatures up to 350°C (660°F) and are suitable for machines used in the metal industry or industrial ovens.
- They are divided into two designs: single-row single-row deep groove ball bearings; and double-row bearings, which have two-row ball bearings. They can also be made into different sizes and different loads according to their use, from miniature ball bearings for light-duty and small parts to large deep groove ball bearings and heavy-duty deep groove bearings.
- Replacing deep groove ball bearings with plain bearings can provide a range of benefits, including reduced costs, reduced maintenance, greatly reduced noise at low speeds, and easier installation. Sliding bearings can also have higher load carrying capacity, simplified assembly, longer service life, smaller bearing seat size, assembly size and weight.
- The ball bearing unit consists of a precision wide inner ring bearing assembled in a bearing seat made of cast iron or pressed steel. The device is pre-lubricated and designed to be slidingly fitted to the shaft. The locking method is set screw locking, eccentric self-locking or concentric.
- On cast iron and pressed steel devices, the outer diameter of the bearing and the inner diameter of the housing are spherical, allowing the bearing to rotate within the housing to accommodate the initial alignment.
- There are many combinations of bearings and housings to adapt to various mounting surfaces, load requirements, shaft dimensions and size requirements.
- Locking mechanisms include fixing screws, eccentric self-locking and ConCentra locking.
- The allowable working temperature of deep groove ball bearings is limited by the following factors:
- Dimensional stability of bearing
- rings and balls
- cage
- seal
- Lubricant
- Deep groove ball bearings are the most common type of rolling bearing. A basic deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of cages. There are two types of deep groove ball bearings, single row and double row. Deep groove ball structure is also divided into two types: sealed and open type. Open type is the bearing without sealing structure. Sealed deep groove ball is also divided into sealed and rubber cover seal) and oil-proof seal. The structure is also divided into Open type single row deep groove ball bearings, single row deep groove ball bearings with dustproof cover, single row deep groove ball bearings with sealing ring, single row deep groove ball bearings.

The design of double-row deep groove ball bearings is basically the same as that of single-row deep groove ball bearings. In addition to bearing radial load, double row deep groove ball bearings can also bear axial load acting in two directions. - When there is a misalignment between the inner ring and outer ring of a double row deep groove ball bearing, it will cause additional load.
- This increases the load on the steel ball and cage and shortens the working life of the bearing. Therefore, the allowable angular error is only 2 arc minutes. Any greater angular error will result in an increase in noise.
- Double row deep groove ball bearings are equipped with two glass fiber reinforced nylon 66 cages. Deep groove ball bearings equipped with nylon cages can operate at temperatures of up to 120°C.
- The characteristics of the cages are not affected by the lubricants used in general rolling bearings, except for certain synthetic oils or synthetic oil-based greases and lubricants for high-temperature applications that contain a large number of extreme pressure additives.
- Stainless steel deep groove ball bearings are corrosion resistant when exposed to moisture and some other media. They can be covered (with seals or protective caps) or open. Open bearings with caps are also available, and they may have recesses on one side of the ring.
These bearings have a lower load carrying capacity than bearings made of high chromium steel of the same size.
Single row deep groove ball bearings with filled grooves have a filled groove on the inner and outer ring that can hold more balls than a standard deep groove ball bearing. - Bearings with filled grooves have a higher radial load carrying capacity than bearings without filled grooves, but their axial load carrying capacity is limited. They also cannot run at high speeds like bearings without filled grooves.
Deep groove ball bearings with filled grooves are available in open type or with protective cover on one or both sides. They are also available with or without snap ring grooves. - Open-end bearings with dust caps are also available. The outer ring can have a groove.
Large size deep groove ball bearings can be supplied with filled grooves and without cage on request.

FAQ
Due to their internal design, ball bearings cannot usually be disassembled down to the component level; therefore, they cannot usually be refurbished.
Solid base shells are manufactured without cavities and fillers; they are stronger than hollow bases, and there are no traps for bacteria and fungi to grow. In the thermoplastic shell, the sturdy base will not break under steam or high-pressure washing. The hollow base saves material and weight to reduce costs. Some people use epoxy resin to backfill the hollow base to eliminate the trap of bacteria breeding, but this will not increase the strength, will cause the installation surface to be uneven, and water will seep between the shell and the filling material, causing cracking.
Use particularly thermally stable bearing rings, larger internal clearance (C4), specially selected lubricants that will not decompose at high temperatures, and zinc anodized flinger. There are two basic versions of our high temperature bearings. The suffix “C4HR5” represents the bearing that can withstand 400°F, and the suffix “C4HR23” represents the bearing that can withstand 450°F.
For critical applications such as pulp and paper processing, printing and packaging, material tearing can cause expensive downtime due to excessive torque and vibration.
The two biggest factors affecting the starting and running torque of the bearing are the seal design and lubricant selection. The shaft and bearing seat fit, component accuracy and surface finish, and retainer design also have some influence.
In higher speed applications, non-contact sealing devices are usually required to minimize operating torque and heat generation, so oil baffle rings and secondary sealing devices are usually required. Flowing oil lubrication systems are usually the best solution.
After proper installation, most seated bearings only need to be relubricated regularly with a small amount of grease and checked to ensure that they operate at low temperatures, quietness, and sufficient accuracy.
This depends on many factors, such as the application’s load conditions, operating speed, duty cycle, temperature, and operating environment. The technical information section of this website provides some basic information. Our engineers can help you determine more specific theoretical life calculations.
When noise and/or operating temperature increase or operating accuracy decreases, bearings should be replaced.

The noise emitted by the bearing may be caused by a combination of one or more factors, such as insufficient working clearance, excessive working clearance, changes in working clearance due to temperature, damage to the contact area, contamination, inappropriate lubricants or The raceway is damaged.
Lubricants have five basic functions for bearings:
Reduce friction
Reduce wear
Reduce temperature rise
Minimize corrosion
Seal contaminants
We do not recommend mixing grease. Mixing incompatible greases will cause the mixture to harden, preventing it from releasing any oil. Mixing incompatible greases can also soften the mixture, which releases all the oil. In either case, the mixture will not be able to properly lubricate the bearing. We strongly recommend using the same type of grease originally provided with the bearing.
