| Mounting Type | Fixed–supported | Affects rigidity and critical speed |
| Shaft Material | GCr15 | High carbon chromium bearing steelGB/T 18254 |
| Nut Material | GCr15 | Same as shaft for hardnessGB/T 18254 |
| Weight | 1–50 kg/m | Depends on diameter and lead |
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:
| pressure: | Not applicable (mechanical component, not fluid pressure) |
| other spec: | Max axial load: 5-500 kN (depending on diameter), Max speed: 1-5 m/s, Accuracy grade: C0-C10 (ISO 3408) |
| temperature: | -20°C to 120°C (standard), up to 200°C with special seals/lubrication |
Indicative industry ranges for design and RFQ preparation. Confirm the exact figures and applicable standard with the manufacturer before specifying.
Quoted from the published standard.
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.
Accuracy grades range from C3 to C7, with C3 offering higher precision. The specific grade required depends on the application's positioning accuracy needs. Always confirm the grade with the manufacturer.
Backlash is minimized through the use of recirculating ball bearings and preloading techniques. The specified backlash is ≤0.02 mm, but actual values depend on the model and preload. Verify with the supplier.
Common materials include high-carbon chromium bearing steel (GCr15), stainless steel, and ceramic-coated steel. Material selection affects corrosion resistance and hardness. Confirm material availability with the manufacturer.
Key parameters such as diameter, lead, and accuracy are referenced to ISO 3408. Shaft and nut materials are referenced to GB/T 18254. These standards serve as procurement references; compliance must be verified with the supplier.
