characteristics of  deep groove ball bearing :

Single row deep groove ball bearings are the most widely used roller bearing type in the world due to their versatility

 and overall performance. They are characterized by having deep raceway grooves in which the inner and outer rings 

have circular arcs of slightly larger radius than that of the balls. They also have non-separable rings. Their straight forward basic design has many advantages:

• Excellent for high speeds
• Good radial load capacity
• Acceptable axial load capacity in both directions
• Have low torque capacity at startup and running speeds
• Can operate with low noise
• Require little maintenance

As flexible as the performance is, the configurations of single row ball bearing is also as versatile. These bearings often have 

steel shields or rubber seals installed on one or both sides and are prelubricated with grease. Also, 

snap rings are sometimes used on the outside edge. While many different retainers are available, 

pressed steel cages are most commonly used. Even tapered bores are available upon special order.

 Series representing the size and load capacity of each. They are:

• 6000 Series - Extra Light Ball Bearings – Ideal for limited space applications
• 6200 Series - Light Series Ball Bearings – Balanced between space and load capacity
• 6300 Series - Medium Series Ball Bearings – Ideal for heavier load capacity applications

Deep groove ball bearings are the simplest yet the most popular bearing:

• Suitable for very high rotating speeds
• Well suited for medium high radial and axial loads in one or both directions
• Various seals and grease variants available for different operating conditions
• Numerous clearance and tolerance classes available for different operating conditions

Series: 600, 6000, 6200, 6300, 6400, 1600; 

• Application examples: electrical motors, general machinery, industrial gearboxes, pumps, agricultural machinery, et

About us:

Semri has a modern production plant and successfully passed the ISO9001 quality system certification. After years of development, the company has grown strength, bearing the annual output of up to 50000000 sets, the annual output value of more than RMB200000000.

Semri has all kinds of professional advanced production equipment and instrument bearings, through joint ventures, cooperation, complete transplant of bearing the most advanced production technology in Europe, with the new grinding, lubrication, sealing technology, design, research and development as the goal, making general bearings and non-standard bearings, localization of imported bearings. The final realization of fully replace imported bearings.

 In order to meet the market demand, the company increased the technological transformation efforts and funding, a big year, a year to a new level, by the factory in the early production of eight types of the development of multi series of nearly a hundred kinds of structure of outer diameter size 100mm-2000mm 2000 specifications and the self lubrication spherical, conical, slewing bearing, split bearings and so on. The products are widely used in metallurgy, mine, petroleum, water, cement, paper, mill, chemical, engineering machinery, heavy machinery, plastic machinery, rubber machinery, and other industries, Semri products are mainly exported to Europe, Southeast Asia, the Middle East and other regions. Precision workshop newly built production of high speed and high precision, low noise bearing for machine tool spindle, large motor, precision rolling mill, precision machinery, to replace imports or to supplement domestic production, cost savings for the user, reduce the purchase cycle, contributed to the industrial development and technological progress.
Semri has perfect quality system, strict control of product quality, with sophisticated equipment, advanced management system, superb technology, professional staff to provide the best quality assurance. Implementation of ISO9001:2011 quality management system standard of Semri will be as in the past. Strive to become one of the leaders in the field of bearing and engine, look forward to working with friends from all over the world to create more brilliant.
