These balls are supremely hard, tough and offer exceptional dimensional stability thanks to their high chromium content and a process which subjects them to very high temperatures, quenches and then 'deep freezes' them.
In addition, because they're ferro-magnetic, they make a decent permanent magnet.
Extremely hard, with impressive corrosive resistance to fresh water, steam, crude oil, gasoline, alcohol, food, blood and perspiration, these balls are also resistant to fatigue by rolling contact, making them a good choice for use in anti-friction bearings.
You'll find these balls in valves, fasteners, 'quick-disconnect' couplings (for hydraulic, medical and pneumatic applications) and locking mechanisms; they're also widely used in the aviation and aerospace industries.

Accuracy is our trademark at TN UK. We pride ourselves on our ability to measure and calibrate the products we manufacture. Housing some of the most sophisticated equipment in the world, our annually assessed UKAS lab means we guarantee the precision of the products we supply.
On top of that, we maintain regular and open communication directly with you and any relevant departments to ensure that you get exactly what you need when you need it.
We also offer a recalibrate service for your existing gauges, CMM Reference balls and Master Ball Sets. So you can rest assured that, whether we are supplying a new product or recalibrating an existing one, by meeting our strict standards, your company meets its strict standards (particularly important for other calibration assessed companies).
