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.
