The Problem with Oversized Gantry Solutions
Small and midsize automotive manufacturing applications have long faced a mismatch in the gantry automation market. Traditional heavy-duty systems from major equipment suppliers come with premium pricing, extended lead times, and capabilities that far exceed what many production lines actually need. Bell-Everman's ServoBelt technology is positioned to fill that gap, combining the precision of rack-and-pinion drives with cost savings and faster delivery. The company claims lead times often less than half those of larger suppliers, making it an attractive option for manufacturers under pressure to automate quickly.
How ServoBelt Works
The ServoBelt system uses a belt-rack hybrid drive that eliminates belt stretch over any travel distance, a persistent limitation in traditional continuous-loop or OMEGA-type drives. This engineering approach allows longer gantry spans without sacrificing positioning accuracy. The system operates at 3 meters per second, well within its 4 m/s maximum capability, while delivering quarter-millimeter positioning precision. For applications that require reliable, repeatable motion across extended distances, the stretch-free design is a significant technical advantage.
