Bearings keep money flowing after 30 years

Spyraflo bearings remain an integral part of NCR ATMs after 30 years of use.
In 1977 NCR was developing the first of its line of ATM machines, the forerunners of the machines now seen in every bank and on every street corner.
The challenge NCR engineers faced was finding a bearing that required no maintenance, could be securely mounted in the side frames of the cash cassettes and could accommodate mounting hole misalignment.
The application demanded 24-hour operation every single day of the year.
Spyraflo submitted the FSB-375 self-clinch, self-align, oil filled bronze bearing to NCR for in-depth testing.
The bearings handled extreme heat, cold, wet and dry conditions.
To meet the rigours of ATM applications, Spyraflo modified its 0.375in diameter bearing to give NCR environmental protection.
This Spyraflo bearing quickly became the standard choice in the NCR ATM line.
Later NCR added more Spyraflo bearings to its stable, including the FSSD-250 self-clinch, self-align, Delryn bearing which is used in its card reader module.
The bearings have withstood the test of time and have remained the first choice for this demanding application.
NCR ATM customers increased performance demands exponentially going from 1,500,000 transactions in five years in 1982, up to 5,000,000 transactions over three years today.
Thirty years later the Spyraflo bearings remain an integral part of NCR ATMs.
