Overview of Deep Groove Ball Bearings
The basic type of deep groove ball bearing consists of an outer ring, an inner ring, a group of steel balls and a group of cages.There are two types of deep groove ball bearings: single row and double row. Deep groove ball structure is also divided into sealed and open structure. Open type means that the bearing does not have a sealed structure.
The dustproof seal cover is made of steel sheet stamping, which only plays a simple role in preventing dust from entering the bearing raceway.Oil-proof type is contact oil seal, which can effectively prevent grease spillover in the bearing.Single row deep groove ball bearing type code is 6, double row deep groove ball bearing code is 4.Its structure is simple, easy to use, is the production of the most common, the most widely used kind of bearings.
Features of Deep Groove Ball Bearings
Deep groove ball bearings are the most commonly used rolling bearings.Its structure is simple and easy to use.Mainly used to bear radial load, but when the radial clearance of the bearing is increased, it has the performance of a certain angular contact ball bearing, and can bear radial and axial combined load.
Applications of Deep Groove Ball Bearings
Deep groove ball bearings can be used in gearboxes, instruments and meters, motors, household appliances, internal combustion engines, traffic vehicles, agricultural machinery, construction machinery, engineering machinery, roller type roller skates, yo-yo, etc.
Classification of Deep Groove Ball Bearings
According to the size of deep groove ball bearings, they can be divided into:
1. Miniature bearings ---- bearing with nominal outside diameter size range below 26mm
2. Small bearings ---- bearings with nominal outside diameter range of 28-55mm
3. Medium and large bearings ---- bearing with nominal outside diameter size range of 120-190mm
4. Large bearings ---- nominal outside diameter size range of 200-430mm bearings
5. Extra large bearings ---- bearing with nominal outside diameter size range of more than 440mm.
