How Ball Bearings Are MadeVIDEO ON THE TOPIC: 1 Minute Produces 1000 Bearings - German Automatic Bearing Assembly Line - Global Technology
The company manufactures and supplies bearings, seals, lubrication and lubrication systems, maintenance products, mechatronics products, power transmission products, condition monitoring systems and related services globally. SKF is the world's largest bearing manufacturer,  and employs 44, people in manufacturing units.
It has the largest industrial distributor network in the industry, with 17, distributor locations encompassing countries. Sven Wingqvist , at the time a thirty-year-old plant engineer responsible for repairs and maintenance at Gamlestadens Fabriker, was dissatisfied with the performance of the ball bearings then in use. These were rigid ball bearings, imported from Germany , and if the long shafts on the machinery in a textile mill were the least bit misaligned, the ball bearings would become overheated and break down, bringing production to a costly halt.
In spring , Wingquist presented a breakthrough — a double row self-aligning ball bearing with a spherical raceway in the outer ring, shared by both rows of balls.
This allowed the inner ring to align freely in relation to the outer ring, with no negative impact on the function of the bearing. The new bearing solved the problem associated with misalignment of the shafts and thus did away with the frequent production stops.
Self-alignment was particularly useful in the less-than-perfect machinery of the times and in buildings with subsidence problems, which was the case at Gamlestadens Fabriker, since much of the land on which Gothenburg has been built is clay. On 16 February , Wingqvist applied for Swedish patent No. The Patent was granted on 6 June in Sweden coinciding with patents in 10 other countries. The new ball bearing was successful from the outset. Three years after SKF was founded, the company had employees and a subsidiary in the United Kingdom.
Manufacturing operations were later established in multiple countries. By , SKF was represented in 32 countries and by , a staff of over 21, were employed in 12 manufacturing facilities worldwide with the largest in Philadelphia , United States. SKF began its operations in India in by establishing a trading outpost in Calcutta. The early operations involved importing of automotive bearings.
Ltd and Investment Corp. In the beginning, the company functioned as a subsidiary automobile company within the SKF group. SKF funded the production run of the first thousand cars, built at Hisingen in Gothenburg , beginning in SKF used one of the company's trademarked names: AB Volvo, which derives from the Latin "I roll", with its obvious connotations of bearings in motion. The ownership of Volvo lasted until when the last shares were divested.
In the s SKF embarked on a massive production rationalisation program in Europe. A visionary project, "Production Concept for the 80s" was launched with the aim to run the night shifts practically unmanned. To increase productivity and safeguard the product quality, a continuous, automatic flow of bearing rings was needed, so SKF developed the Flexlink brand.
FlexLink created the multiflex plastic chain conveyor system to solve the business requirements. SKF divested FlexLink as a separate company in Since its founding, SKF's company headquarters have been located in Gothenburg. It also supplies bearings for Ferrari racing vehicles, used in Formula One races,  and is a sponsor of F1. Another focus area is the energy sector, including wind turbines which generate electricity.
SKF runs its own business excellence program for continuous improvement Kaizen of its business processes in all parts of the company. The program is based on previous initiatives like TQM and integrates with lean management also statistical methods of Six Sigma along with related project management. Its operations are also certified to either ISO or applicable customer industry standards, e.

A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It achieves this by using at least three races to contain the balls and transmit the loads through the balls. In most applications, one race is stationary and the other is attached to the rotating assembly e.

Rotary bearings, whether they are ball, roller, plain or needle bearings, are used in almost any application involving rotary motion, such as automobile wheels, dentist drills, machine tool spindles, draw bridges, motors, pumps and thousands of other applications. Ball bearings are rolling element bearings that use balls to separate the bearing races and provide smooth, low friction motion in rotary applications. Ball bearings are manufactured in hundreds of sizes, from the ultra-small 1. How are ball bearings made, and how do they get the balls so round? The answer is a multi-step manufacturing process involving machining, heat treating, grinding, honing, lapping and assembly. Although there may be variations, the following process applies to the vast majority of standard ball bearings produced today. Components Ball bearing construction Ball bearings are comprised of two bearing rings or races , balls and depending on the type a retainer to maintain ball separation.
How do they get the balls in ball bearings so perfectly round and smooth?
Special bearings, complete assemblies or optional lubrication — we have the solution for you. Standard roller bearings usually represent a compromise between speed, load rating and an economically justifiable production quantity as well as the manufacturing effort. In addition to our product portfolio, we develop and manufacture roller bearings for high ambient temperatures; custom-made for each application. With our high-temperature bearings, we offer premium products that we equip or manufacture for the corresponding temperature range.

How ball bearings are manufactured
Ever since man began to need to move things, he has used round rollers to make the job easier. Probably the first rollers were sticks or logs, which were a big improvement over dragging things across the ground, but still pretty hard work. Egyptians used logs to roll their huge blocks of stone for the pyramids. Eventually, someone came up with the idea of securing the roller to whatever was being moved, and built the first "vehicle" with "wheels. It wasn't until the late eighteenth century that the basic design for bearings was developed. In , Welsh ironmaster Philip Vaughan patented a design for ball bearings to support the axle of a carriage. Development continued in the nineteenth and early twentieth centuries, spurred by the advancement of the bicycle and the automobile.
The extended product line includes a complete offering of open, shields, seals and snap ring combinations.

B bearing has a double row structural architecture, Inside diameter : 2 in Outside diameter : 0.
If you have ever rolled a couple of those little metal balls found in a ball bearing around in your hand, you have noticed how perfectly round and incredibly smooth they feel. You might have wondered how anything could be made that perfect. It's actually a pretty neat process that starts with a metal wire and ends with a perfect shiny ball. The first stage in the process is a cold or hot forming operation.
Hefei JD Bearing Co. We manufacture bearings for a variety markets, such as, agriculture, construction, health, machine tool and general industry. That is the reason for our continuing growth and success.
