CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
Dynamic load rating (per ISO 14728-1) indicates the load that provides a rated service life under repeated motion. Static load rating (per ISO 14728-2) is the maximum load without permanent deformation. Both are reference values; confirm for your application.
Accuracy grades (C1–C5) per ISO 10242 define the precision of the carriage's movement. C1 is the highest precision, while C5 is standard. Choose based on the required positioning accuracy of your machinery.
Preload (classes Z0–Z3) adjusts the internal clearance between rolling elements and raceways. Higher preload increases rigidity and reduces play but may increase friction and wear. Select based on load and stiffness requirements.
The operating temperature range is -40°C to 85°C. Outside this range, lubrication may degrade, affecting performance. For extreme temperatures, consult the manufacturer for suitable lubricants and seals.
