Buy & Import C7 Ball screw with Double Flange Ballnut from Fbt International Industries Ltd. - Wholesale Supply

The C7 ball screw with double flange ballnut supplied by Fbt International Industries Ltd. is a precision linear motion component made from carbon steel SCM440 and chromium‑molybdenum alloy steel. It conforms to the C7 rolled grade, delivering the positional accuracy required by CNC machines and robotic axes. The double‑flange ballnut provides radial support and maintains axial rigidity during continuous operation. The product is listed under the BSF series covering models from 1605 to 3210.

Each model in the series differs in nominal diameter and lead, allowing selection of a size that matches the load and speed requirements of the machine. The rolled C7 grade offers a balance of precision and cost, while the double flange design reduces deflection under high axial loads. Typical industry practice pairs these screws with mineral‑oil lubrication and standard ISO‑2409 compliant fittings. The supplier highlights reliability, smooth movement and the ability to produce custom lengths on request.

These screws are commonly installed in high‑speed milling, drilling and packaging equipment where repeatable positioning is critical. Buyers such as equipment manufacturers and system integrators usually request certification of material composition and dimensional inspection reports. Trade terms, minimum order quantities and payment conditions should be confirmed directly with the supplier before placing an order.

Frequently Asked Questions About C7 Ball screw with Double Flange Ballnut from Fbt International Industries Ltd.
The shaft is fabricated from carbon steel SCM440 combined with chromium‑molybdenum alloy steel, as specified by the supplier. This composition provides good wear resistance and tensile strength for linear motion applications.

Sourcing C7 Ball screw with Double Flange Ballnut from Fbt International Industries Ltd. - China Import Guide

Before confirming a purchase, importers should obtain the material test certificate for the SCM440/Cr‑Mo alloy and verify the dimensional inspection report for the selected diameter and lead. Request photographs of the double‑flange ballnut to ensure the radial support features are present. Confirm that the supplier can provide a compliance statement for ISO 2409 or an equivalent standard.

Logistics arrangements, including Incoterms such as FOB Wenzhou or CIF Shanghai, need to be agreed in advance, as the supplier does not publish default terms. Lead time for standard BSF models is typically several weeks, but custom lengths may require additional production time; obtain a confirmed schedule from the factory. Payment methods, often a TT advance or LC at sight, should be stipulated in the contract and verified with the supplier’s banking details.

Importers are advised to appoint an independent inspection agency to perform pre‑shipment checks on dimensional accuracy, surface finish and ballnut integrity. Request the supplier’s inspection certificate and, if possible, a third‑party test report covering hardness and wear resistance. Ensure that the shipment includes a packing list, material certificate and a certificate of origin to facilitate customs clearance.
