Deep Groove Ball Bearings
deep groove ball bearings are one kind of radial bearings widely used. They are simple in structure non-separable cheap in its price. In addition they require little maintenance in service as well as are capable to be operated at high speeds.
Both the inner and outer ring of single row deep groove ball bearings have a deep groove raceway in addition the good sealing quality between raceway and ball can make bearings carry radial loads as well as certain axial loads. After the radial clearance is increased properly axial load carrying capacity will be improved accordingly. That’s the reason why it can replace high speed angular contact ball bearings in some cases.
Sealed Bearings
deep groove ball bearings have various types in structure. Not only open type bearings are provided but also the bearings with shield or seal at one side shields or seals at both sides.
The seal ring can be divided into contact and non-contact (low frication) according to contact ways. Usually the bearings with seals at both sides have been filled with grease lubricant before delivery. The filler amount would be 25%-30% of the effective space in bearings. If customer has special requirements other types of greases can be filled and the filler amount could be adjusted accordingly.
The bearings sealed at both sides are forbidden to wash and heat (oil heating) over the temperature 800 prior to mounting. Otherwise damages to bearing or grease leakage must be caused. The bearings with seals can keep reliable operation at working temperature between -30 Celsius degree and 100 Celsius degree.
Contact sealed bearings should not be chosen to use in high speed working conditions because friction existing between seal and inner ring of the bearing would make the ambient temperature higher than non-contact sealed bearings. As a consequent contact sealed bearings are suitable for middle or slow speed working conditions.
Deep groove ball bearings with a snap ring groove
Deep groove ball bearings with a snap ring groove can be located by a snap ring. When installing they can be fastened in the housing by a snap ring. So when the mounting position is limited a deep groove ball bearing with a snap ring groove is the first choice.
After combined design shields seals and snap ring groove mentioned above can be provided according to different applications.
Low-Noise Bearings
In order to meet users’ special needs of bearings with low noise (or low vibration) can provide users deep groove ball bearings with different levels of vibration. The bearings are identified by suffix and its definition is explained in chapter of bearing designation.
can provide customers deep groove ball bearings with other structures such as insulative deep groove ball bearing ceramic deep groove ball bearing stainless steel deep groove ball bearing and full ball bearing with filling slot etc. If customers need please consult technical department.
also design and manufacture other types of deep groove ball bearings for customers with special requirements.
Cages
deep groove ball bearings are supplied with a pressed steel cage a machined solid cage or glass fiber reinforced polyimide 66 and other engineering plastic cages. Cages of different materials are identified by suffix and the designation is explained in chapter of bearing designation.
