Glossary

A

Axis body

The axis body is a precision aluminum profile.

B

Breakaway torque

The breakaway torque describes the drive torque required to overcome the static friction and that initiates the transition to sliding friction.

C

Cantilever axis

In the case of a cantilever axis, the axis body is stationary while the end plates are moving.

F

Feed constant

The feed constant (feed per revolution) is the distance which the end plates move per toothed belt pulley revolution.

M

Mechanical drive element

Depending on the axis, the mechanical drive element of the axis consists of the toothed belt and the toothed belt pulley or gear rack and rack pinion.

Mounting position

The axis can be installed in any desired mounting position. However, all external forces and torques must be within the ranges of permissible values.

R

Repeatability

Repeatability is the accuracy with which it is possible to move to a previous position again under the same conditions. To determine this value, the end plates are moved to the end position from the same direction.

S

Sensor

Inductive proximity sensors are used as sensors for limit switches or reference switches. These sensors have not a safety function.

Service life

The service life is the distance in kilometers (miles) before the first signs of material fatigue can be seen on the guides, the mechanical drive elements and the bearings. Service life specifications (kilometers covered) relate to the nominal values specified in the data sheet. If the nominal values are exceeded, the service life decreases accordingly.
