Ballman Industries

Balls made of this material offer excellent resistance to corrosion in general. The most common uses include various types of industrial pumps and valves. Brass is resistant to corrosion caused by fuel oils, gasoline (petrol), butane, benzene and other similar types of corrosive chemical agents. It is also resistant in environments where air and salt water are present.

the second production step is the rolling between plates with concentric grooves in order to eliminate the heading witness marks and to increase the precision of the ball in this operation the spheres are ground between two concentric pressure plates to correct the spherical shape and remove the seam formed in the cold forging.

Here the hardened balls are ground to improve surface finish and geometrical parameters. Several careful grinding processes with ceramic wheels lead to a higher size precision preparing the balls for the next final lapping operation.

the balls are heat treated, i. E. Hardened and tempered to attain the desired level of hardness and microstructure the heat treatment, when necessary, gives the maximum possible hardness and the desired microstructure to the ball and therefore the best obtainable technical features in compliance with materials used.

to ensure the highest quality each and every parameter of the balls is thoroughly inspected before packing and dispatch. All precision, hardness, material features, etc. Are tested at every stage of the production and again before shipping, at the end of the manufacturing process, in order to assure and guarantee the quality. Each lot of balls is inspected with optical machines effecting a surface visual test, where the defective ball gets rejected at the same time a test of physical integrity of balls is effected by eddy current probes, if required. These are 100% checks by skilled personnel.

the final lapping operation gives the ball a perfect bright, compact surface, without any defect, with a very low surface roughness, very low deviations from spherical form, very low roughness values, very low waviness values and total lack of surface defects assured by optical control machines, are the four basic parameters which guarantee final customer an extremely qualified product for its relevant use.

52100 Chrome alloy steel balls and rollers offer high hardness and excellent resistance to wear and deformation. They are made from the finest bearing quality steel. 52100 material is specified by precision bearing manufacturers where precise spherical and tolerance accuracy are required.

balls made of this material are used for applications requiring extreme hardness and resistance to wear and abrasion, hard shocks and impacts.

the applications include special valves, flow meters, re-circulating ball bearing screws, linear bearings and balls for ball-point pens. They are also used often for minting, as pivots and points of comparators. They are also used for measurements or calibration of holes and measurement checking devices.

Balls of this material have the advantage of being through hardened and will take higher loads and provide longer life than case hardened balls, for such applications as the cycle industry. These balls are substantially cheaper than balls manufactured from high carbon chrome alloy steels.

302 & 304 stainless steel balls are an austentistic, unhardened stainless steel with excellent resistance to corrosion by oxidizing agents, most organic chemicals, food stuffs and sterilizing solutions.

the most widely used type of ceramic due to very high resistance to
wear and abrasion in general. It has a micro - structure specially designed for applications subject to great stress. It does not require lubrication, it is resistant to corrosion, anti magnetic and electrically insulating, and it continues to be efficient at high temperatures up to +1400 oc. It combines extreme hardness with a high precision ball. Si3n4 balls are widely used in high precision bearings in the airspace industry, for machine tools, measurement instruments, mechanical centrifuges, radar and missiles, pumps and compressors.

calculated length of wire is sheared and cold forged in a close die to give it the spherical shape.

the wire rod is drawn to the required size,in closer tolerances so that it can be used in cold forging.

This material has high strength to weight ratio. Also it has excellent heat and electricity conductivity.

Aluminum balls are highly resistance to corrosion but has a low mechanical strength. These balls are used for electronic industry.

Generally low carbon balls (either soft or case hardened) are first copper and then nickel plated in order to achieve good corrosion resistance at lower price than costlier stainless steel balls.

The most common applications include cosmetics (nail polish), stationary products (e.g. anti-drying agent for felt pens and correction fluids), toys (flippers and pinball tables, chinese checkers), and gadgets in general.

This material is universally used in valves and pumps where the greatest resistance is required to corrosion caused by strongly oxidizing acids.

Hastelloy-C276 is resistant to strongly oxidizing agents such as chlorine, nitric, acetic, formic, phosphoric, sulphuric and hydrofluoric acids, zinc chloride and ammonium solutions, water-based solutions containing chlorine or hypo chlorites and acid solutions of ferric and cupric salts.

Hastelloy-D is exceptionally resistant to any concentration of sulphuric acid, up to its boiling point.

Monel is widely used in the chemical, pharmaceutical, maritime, oil, textile and paper industries. 

It is highly resistant to (caustic) alkaline solutions, sea water and diluted sulphuric acid.

Monel-K (500) is often used when higher hardness and resistance are needed.

S-2 Tool Steel balls find most frequent use in oil field equipment and offshore drilling operations. They provide good service in withstanding the abrasion or pulverized rock and mud slurries

Used extensively in check valves for transporting chemicals. They have high resistance to wear, abrasion and heat.

High Technology material used extensively in aircraft applications because of low weight with high strength.
