Round objects, like ball bearings, have always been used to make jobs easier. There are many types of rolling bearings that also come in a wide variety of sizes. Most commonly, ball bearings can be held in the palm of your hand. When examining how ball bearings are made, we must first look at the materials used. Most ball bearings are made of steel.

Spanning the globe with specialized precision.

Manufacturing ball bearings is cheap, quick and efficient which is one of the reasons they are used so prolifically in engineering. The main challenge of creating a high quality bearing is ensuring that a near perfect spherical ball is created with a very smooth surface, resulting in fast movement with minimal friction. Although manufacturers have pretty well mastered this art , a group of students in the 80s came up with a method of absolutely guaranteeing the highest quality of stainless steel ball bearings. Their ambitions were beyond sky high; the 12 students proposed travelling into outer space to take advantage of zero gravity and produce a bearing like no other. Little did they know that under ten years after they came up with the idea, four of them would live to see it happen. The experiment began in at the California State University in Northridge. The group had hoped to launch the experiment as soon as , but competition for places was fierce and certain safety requirements had to be met which proved challenging.

The Science Experiment Which Took Off Like A Rocket - Creating Space Ball Bearings

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.

Getting a student-designed science experiment into space is almost as difficult as making a perfect metal sphere. After almost seven years of false starts and bureaucratic delays, their experimental device for making a flawless ball bearing in space has been loaded aboard the space shuttle Columbia, which is scheduled to lift off from Cape Canaveral Wednesday morning. He and the other three members of the team will travel to Cape Canaveral to watch the launch. But now that it is so close I am getting really excited. The experiment began in as a project by 12 CSUN engineering students, who have long since graduated and gone on to other careers. But a nucleus of four graduates, who kept the project going, hope that they will finally see their device go into space. The CSUN group devised a self-contained, battery-powered unit to melt small cubes of metal alloy suspended in wax. Theoretically, in the zero gravity of space the metal should form perfect spheres, which are impossible to create on Earth because gravity inevitably deforms the metal.

Robert Heinlein said that common wisdom is almost always wrong, by a factor of at least ten thousand to one. Harry Stine. Stine believed that access to the space environment, including weightlessness, vacuum, and radiation, would revolutionize manufacturing. Instead, microgravity is viewed as a research tool. The emphasis is on understanding phenomena that can improve processes on the ground. Once we understand how something works in microgravity, we can almost certainly find ways of reproducing the observed phenomenon more cheaply on the ground. In fact, products have already been manufactured in space and sold on Earth. Monodisperse spheres can be made on Earth, but there are difficulties in making them beyond a certain size because gravity interferes. John W. Monodisperse microspheres have a number of medical and research applications. In addition, they can potentially be used to carry drugs and radioactive isotopes for cancer treatments.

Ball Bearing

All moving machines have rotating axes. Those axes are supported by bearings. Ball bearings use the low-friction rolling of balls to realize the smooth rotation of the shaft and the efficient transmission of kinetic energy to the various parts of the machine. This contributes to energy savings, longer life and reduction of breakdowns for the machinery. A precision of the bearings is linked directly to a precision of the machinery. Ball bearings consist of four components — an outer and inner ring, a retainer, and the balls. The outer and inner rings support the rotational motion, the balls reduce the friction from that rotational motion, and the retainer keeps the balls in place. Lubricant is also added to make the movement even smoother, and some form of shielding is applied to prevent the lubricant from leaking. Basic composition of a ball bearing. Multi-function copier-printers used in offices and other situations use many bearings, which need to be highly durable and provide precise, stable motion.

From miniature ball to large-diameter roller and from super duplex to thin section designs, every component is engineered for precision, performance and life-critical reliability. Products include standard catalog bearings, specialty designs for ultra high speed operation , rpm , duplex and super duplex bearings, and custom solutions for demanding applications. A majority of the products we manufacture are nonstandard solutions containing special features that satisfy a variety of mounting and operating requirements. Thin Section Ball Bearings manufactured by MinebeaMitsumi Aerospace companies are utilized in small to very large mechanical systems where bearing size and weight need to be kept to a minimum and when high accuracy, high stiffness less deflection , and low friction are required. Targeted applications include accessory gearboxes, power control actuators, helicopter swash plates, high lift actuators, and space cargo capsule applications. The full product series includes standard catalog items, more complex assemblies like integral duplex thin section bearings and tapered thin section roller bearings, and completely custom engineered solutions.

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.
