Brass Flanged Trapezoidal Lead Screw Assembly - Wear-Resistant Self-Lubricating Transmission Nut, Custom OEM Manufacturer

This assembly combines a high-gloss brushed brass flange with a precision trapezoidal lead screw, forming a critical linear motion conversion unit for mechanical transmission systems. The wide flange face, featuring evenly distributed mounting holes, provides a stable axial reference, effectively dispersing locking stress to prevent loosening. The precisely machined internal threads engage tightly with the high-strength external screw, ensuring smooth transmission and precise positioning under frequent reciprocating motion. It is commonly used in CNC machine feed mechanisms, fine-tuning modules for automation equipment, and lifting control for valve actuators.

Manufacturing utilizes composite CNC turning and milling processes, with strict control over the perpendicularity of the flange face relative to the screw axis, as well as the pitch diameter tolerance and thread profile accuracy. This prevents wobble or binding after assembly. To address the soft nature of brass and its tendency to adhere to cutting tools, cutting parameters are optimized to suppress deformation and eliminate burrs. Fine chamfering on flange edges and thread roots ensures operational safety and meets cleanliness standards. For tight clearance fits, outer diameter tolerances are strictly controlled to ensure smooth insertion without looseness.

Equipped with high-precision CNC lathes, machining centers, and CMMs, we support non-standard customization based on 2D/3D drawings. Options include various materials (e.g., H59/H62 brass, tin bronze) and thread standards (e.g., Metric Tr, Imperial Acme). Adhering to ISO 9001 quality management systems, our production process covers material traceability, go/no-go gauge inspection for key dimensions, and 100% visual inspection. We provide material certificates and test reports, ensuring that batch deliveries meet the stringent standards for fit precision and wear resistance required by mechanical manufacturing, semiconductor equipment, and high-end automated production lines.
