Saige Wholesale Threaded Steel Balls Low Friction High Hardness Spheres 4.5mm 8mm 10mm 12mm in Stock

Saige Wholesale Threaded Steel Balls Low Friction High Hardness Spheres 4.5mm 8mm 10mm 12mm in Stock. Precise CNC drilling, regular hole shape and smooth hole wall, strictly controlled concentricity and position tolerance. Through holes, eccentric holes and multi-directional porous processing are available to meet special structural needs such as diversion, flow splitting and limiting. The sphere maintains stable structure after drilling without deformation and stress cracking, no burst under high pressure working conditions. Customizable hole sizes, both small-batch samples and large-scale standardized production are available. The porous structure optimizes fluid velocity, reduces pipeline medium eddy current and internal impact wear of valves. Convenient positioning during assembly, fast combination with valve stems and positioning buckles to reduce manufacturers' assembly labor cost. Integrated thread forming by precise thread rolling and turning, regular smooth thread profile, tight occlusion without thread slipping and decoupling. Custom internal thread, external thread, single thread and double thread, applicable to valve stem fastening, connecting rod connection and fixed limit. High coaxiality between thread and sphere, no skew after tightening, smooth valve rotation without jamming. Hardened thread, thread teeth will not wear flat after repeated disassembly and tightening, long-term stable fastening performance.
