Our motion control rigs are generally provided with a bearing type rail offering a superior foundation for very high precision shooting. For cost/portability considerations they can also run on industry standard dolly track, however this does not offer the same precision and rigidity as bearing rail. Lightweight bearing track is easy and quick to set up on location or in the studio due to its inherent rigidity and straightness. Mark Roberts Motion Control supply our own linear v-block ball-bearing rail which gives greater stability than any other type of track, while remaining still an easily transportable system.
The lightweight bearing track uses the same high quality bearings as Precision Bearing rail used for the Milo track but are constructed from lighter aluminium extrusion than the purpose built single welded fabrication of the Precision bearing track. As such they are a little lighter and can be taken apart if needed for transportation (although it is recommended they are transported whole).
Light weight track generally comes in 3m lengths, and can be easily joined together. Lengths of 1.2m and 1.8m are also available.
