Deep Groove Ball Bearing Brief Introduction:

Deep groove ball bearings are the most common bearing type. Deep groove ball bearings are most representative of the rolling bearing, widely used.High speed or higher speed operation, and very durable, without regular maintenance. Deep groove ball bearings can be used for transmission, instrumentation, motors, appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, engineering machinery, roller skate style, yo-yo and so on.Deep groove ball bearings generally use pressed steel cage or brass cage. When the outer diameter is less than 400 mm, use steel stamping cage.When the outer diameter over 400 mm,use brass cage with "M" suffix.Bearing function: supporting moving parts, reducing friction.

Deep Groove Ball Bearing basic structure:

Deep groove ball bearing has single and double rows structure, also sealed and open type.Open means bearing without seals.Anti-oil type of contact seal, which can effectively prevent the bearing grease spills.Single row deep groove ball bearing type code of 6, double row deep groove ball bearing code four. Its structure is simple, easy to use, is the production of the most common and most widely used class of bearings.

Deep Groove Ball Bearing working theory:

Deep groove ball bearings mainly take radial load, but also to support radial and axial load. When the only radial load, the contact angle is zero. When the deep groove ball bearings with a larger radial clearance, the performance with angular contact bearings can bear large axial load, deep groove ball bearing friction coefficient is small, speed is also very high.

Deep Groove Ball Bearing Structure Category:

Deep groove ball bearing structure is simple, easy to reach compared with other types of manufacturing high precision, so easily into a series of mass production, and lower manufacturing costs, the use of very common.Deep groove ball bearings according to sizes can be divided into:

(1) Miniature bearings ---- nominal diameter size less than 26mm;
(2) Small bearings ---- nominal diameter size range of 28-55mm;
(3) Small to medium sized bearing ---- nominal diameter size range of 60-115mm;
(4) Large bearing ---- nominal diameter size range of 120-190mm;
(5) Large bearing ---- nominal diameter size range of 200-430mm.
