LYC 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.
LYC 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 and 100oC.
