BAHR ALLM

Mechanical linear unit with two external roller guides, driven by a linear motor integrated into the unit.



This unit consists of an aluminium profile with hardened steel spindles mounted on top of the profi le. The carriage, which has internal linear ball bearings that can be adjusted free of play, moves along the unit. The linear-motor ALLM unit is based on the principle of a linear, synchronous AC motor. The guiding profi le is fi tted with permanent magnets as stator. 

The carriage is fitted with the actuator. The magnetic attraction causes a force between carriage and guiding profi le also in the absence of current. This force can be used for the initial tension of the bearings. Several carriages can be driven independently on one guiding profile.    

Fitting position: As required. Max. length 6.400 mm without joints.

Carriage mounting: By tapped holes.    

Unit mounting: By T-slots and mounting sets. The linear axis can be combined with any T-slot profi le

Carrigaue Support: In the standard version, the carriage runs on 8 rollers which can be adjusted and serviced. For longer carriages the number of rollers can be increased. Repeatability ± 0,05 mm.

Repeating accuracy: ± 0.05 mm
Travel speed: max. 8 m/s
