Guideway provides quiet operation
Monorail BM can provide load support for direct-drive linear motor or servo-driven ballscrews, where accuracy, stability and precise velocity control are application requirements.
Schneeberger's Monorail BM series, four-row recirculating ball guideway provides automation machine builders with a high- load, high-rigidity linear bearing system that is optimised for exceptionally smooth and quiet operation The low-friction bearing can provide load support for direct-drive linear motor or servo-driven ballscrews, where moderate to micron-level accuracy, high in-position stability and precise velocity control are application requirements

Tables position cost-effective performance
UniSlide and BiSlide positioning tables are aimed at medium precision manufacturing and research applications where cost and performance are highly important considerations.
It is used in a wide range of manufacturing and test applications in electronics, semiconductors, biomedical, scientific equipment and general purpose assembly automation.
A two-point contact bearing preloading system, coupled with a very efficient ball recirculation system, ensures extremely low friction with minimal dynamic push force variation, even under full load.
A trapezoidal rail profile design also allows uniform rigidity and load to be equally distributed in all directions.

Eval kits check out motion controllers
Agile Systems offers evaluation kits to help customers determine performance and functional requirements for their motion control applications.
Rails are available in six standard widths from 15 to 45mm in lengths of up to 6m with matching carriages supplied in a number of styles, some with standard or heavy-duty versions.
Through the range, four accuracy and three preload classes are available to ensure maximum flexibility and cost optimisation for the customer's application.
The running accuracy of the best precision class for an individual carriage and rail is around 3um over 1000mm.
Under normal operating conditions, speeds to 5m/s and acceleration to 100m/s are attainable, with higher values available on request.
The standard carriage design includes double-lipped cross wiper and longitudinal wiper seals, ensuring that lubrication is retained over the maximum useable period.
To further improve sealing, a cover strip is available for the rails.
Serviceability is made easy with lubrication points at the front, top and both sides of the carriage.
A wide range of rail and carriage options include nonstandard hole spacing, special coatings to improve corrosion resistance, vacuum-compatible preparation, wipers and bellows for added environmental protection and brakes and clamps to make installation easier for the customer.
The range can also be supplied with integrated racks for rack/pinion drives and with a length measurement system comprising a directly integrated magnetic scale to combine load carrying, precision alignment and position feedback functions in one convenient package.
