Recently, DLY completed the pre-shipment inspection for a batch of ball screws prepared for overseas customers. Before delivery, our quality control team carefully checked the product appearance, dimensions, nut running smoothness, anti-rust treatment, and packaging condition to ensure that each product was ready for international shipment.
As a professional linear motion components manufacturer in China, DLY understands that stable quality is especially important for distributors, importers, machine builders, and industrial equipment suppliers. For bulk orders, buyers not only care about product price, but also need consistent quality, reliable delivery, and safe packaging.
Ball Screw Appearance Inspection Before Shipment
During the inspection process, our workers checked whether the ball screw surface was clean and smooth, whether the thread was free from visible damage, and whether the nut moved smoothly along the screw shaft.
For precision transmission components, surface quality is not only about appearance. A clean and consistent ball screw surface can help reduce abnormal friction, improve running stability, and support longer service life in machine applications.
Dimension Check for Customized Ball Screws
For customized or machined ball screws, DLY also checks key dimensions according to the customer's requirements. This includes screw length, shaft diameter, end machining dimensions, and other details required for installation with support units, couplings, or machine structures.
Accurate dimension inspection helps customers receive products that are easier to install and more suitable for their equipment design.


Nut Running Smoothness Test
The ball screw nut is also checked before shipment. Our team pays attention to whether the nut runs smoothly along the screw shaft, without obvious jamming, abnormal noise, or uneven movement.
For machine builders and distributors, smooth nut movement is an important sign of stable product quality. It can help reduce installation problems and improve the customer's confidence in bulk purchasing.

Anti-Rust Treatment and Export Packaging
In addition to product inspection, DLY also pays attention to export packaging. Ball screws are precision transmission components, so proper anti-rust protection and strong packaging are necessary for long-distance transportation.
Before shipment, the products are cleaned, protected with anti-rust treatment, packed carefully, and prepared for safe delivery. This is especially important for overseas orders because sea shipping, warehouse storage, and different climate conditions may expose products to moisture.
