corresponds to the wheel rotation axis.
CONE
Conical element with a central hole which, when inserted on the wheel balancer shaft, is
used to centre the wheels having central holes with a diameter ranging between maximum
and minimum values.
DYNAMIC BALANCING
Procedure for unbalance compensation by applying two weights, one on each of the two
wheel sides.
FLANGE (of the wheel balancer)
Circular crown-shaped disk against which the disk of the wheel mounted on the wheel balancer
rests. Also used for keeping the wheel perfectly perpendicular to its rotation axis.
FLANGE (adapter - centring accessory)
Device for supporting and centring the wheel. Also used for keeping the wheel perfectly
perpendicular to its rotation axis.
Mounted on the shaft of the wheel balancer by means of the central bore.
FSP
Fast Selection Program acronym
LOCKING DEVICE
Wheel clamping device on the wheel balancer only used for versions with the automatic
wheel clamping system.
OPT
Optimisation abbreviation.
RING NUT
Wheel blocking device on the wheel balancer, fitted with elements for coupling with the
threaded hub and side pins for tightening it.
RPA
Acronym of Ricerca Posizione Automatica (Automatic Position Search).
SELF-CALIBRATION
This procedure calculates suitable correction coefficients starting from known operating
conditions. It improves the machine accuracy by correcting to a certain extent the calculation
errors that may result from the alteration of the machine's features over the course of time.
SENSOR (measuring arm)
Mobile mechanical element that, when brought into contact with the rim in a specific position,
measures the geometric data: distance, diameter. Data can be measured automatically if the
sensor is equipped with suitable measurement transducers.
SPIN
Procedure starting from the action that causes the wheel to rotate and the subsequent rota-
tion of the wheel.
STATIC BALANCING
Procedure for correcting only the static element of the unbalance, by applying only one weight,
usually at the centre of the rim well. Accuracy increases as the width of the wheel decreases.
THREADED HUB
Threaded part of the shaft on which the ring nut is engaged to lock the wheel. It is supplied
disassembled from the machine.
