Proving
rotors are used to verify the continued accuracy of
a balancing machine, and can also be used to
calibrate a hard-bearing machine. Owning a proving
rotor saves rental costs for similar equipment, and
allows the balancing machine user to verify
performance of his own machine as often as
production, machine usage, and quality programs
require. This can be as often as several times per
day to annually, depending on individual
circumstances.

Standard
Proving Rotors:
Standard rotors allow a known unbalance to
be applied in two separate planes at various
angles. Multiple weight sizes are provided
to accommodate various machine sizes and
speed ranges.
|
SAE Rotors:
SAE rotors are built to SAE (Society of Automotive Engineers)
standard ARP 4162. These rotors are required to evaluate a
balancing machine's performance according to SAE standards (ARO
4048, ARP4050, ARP 5323). Evaluation in accordance with SAE
standards is typically required in aerospace applications. SAE
rotors are available upon request. Please contact our
SalesDepartment. |

Certification:
|
●
|
All rotors are manufactured to tolerances well within Schenck
machine performance specifications, and are thus suitable as
sold for the purposes stated.
|
|
● |
Certification of critical rotor and test weight dimensions,
traceable to NIST (National Institute of Standards and
Technology) is available for an additional charge, please
contact our Sales Department. for more information regarding this
service. Certification data is kept by Schenck Trebel
for a minimum of 5 years from date of certification. |
