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
Sales Department. For more information on Quality
Control for Jet Engines,
please view

classifications for both Standard and SAE Proving Rotors
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. |
