Servo Belt Linear Drive (SBL), Medium


Servo Belt Linear Drive (SBL), Medium

ServoBelt Linear Medium
Type Rotary Drive Linear, NEMA 23, 34 or user motor.

Recommended Maximum Payload (lb)Payload x Acceleration = Linear Force

Linear travel per motor revolution (mm)
Bearing type
Preloaded 4-row ricirculating ball, standard or corrosion resistant
Maximum Length
5.5 m with single-piece chassis
Virtually limitless travel distances with chassis splices

Motor type 3-phase brushless servo or user supplied of any type

Accuracy (µm)Linear accuracy at stage centerline, after two point temperature scale correction.

Linear optical encoder: ±4/meter
Rotary encoder: ±135/full travel

Uni-directional repeatability (µm)Achievable under ideal conditions.

Bi-directional repeatability (µm) ±25 to ±125 depending on deceleration profile.

Angular deviation (±arc-sec)Yaw angle maximum in the plane of the base. Most chassis are flexible enough that this value is generally the achievable number when the unit is straightened on user surface.
