Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
This component is essential for the following industrial systems and equipment:
| speed: | Up to 5 m/s with proper lubrication, acceleration up to 50 m/s² |
| pressure: | Not applicable (mechanical component, not fluid pressure) |
| temperature: | -20°C to +80°C (standard), up to +150°C with special seals/lubrication |
| load capacity: | Dynamic load rating: 5-50 kN typical, static load rating: 10-100 kN typical |
Indicative industry ranges for design and RFQ preparation. Confirm the exact figures and applicable standard with the manufacturer before specifying.

1 company lists this product among what they make. Company figures are quoted from each company's own website; every card states where the relationship came from.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
Common materials include hardened steel, stainless steel, and aluminum alloy. Hardened steel is standard for most applications, stainless steel offers corrosion resistance, and aluminum alloy is used for lightweight or low-load applications.
Accuracy grades range from C1 (highest precision) to C5. Choose based on the required positioning accuracy and repeatability of your application. Higher grades have tighter running parallelism and are more expensive.
Preload eliminates internal clearance, increasing rigidity and reducing deflection under load. It is specified as clearance (C) or preload classes P0 to P3. Higher preload improves stiffness but may increase friction and reduce speed.
Regular lubrication is essential. Use the recommended grease or oil and re-lubricate at intervals based on operating conditions. Keep the rail clean to prevent contamination, and inspect for wear or damage periodically.
