In modern automated machinery, ball screws serve as the core transmission component that converts rotary motion into precise linear movement. Standard ball screw models fit universal equipment, yet many specialized automation, medical, micro-electronic, and precision instrument projects demand customized dimensions, materials, and load performance. Our SHUNTAI custom miniature grinding ball screws (MIA0401, MIA0401b, MIA0601) are engineered exclusively for non-standard industrial motion scenarios. Built from premium GCr15 bearing steel with both rolled and ground machining processes, these compact ball screws deliver long service life, ultra-smooth operation, and customizable specs to match your unique mechanical design constraints. What Makes Non-Standard Custom Ball Screws Indispensable? Unlike off-the-shelf standard ball screws, custom non-standard ball screws are fully adjusted to your project’s exact engineering requirements. They solve pain points that generic transmission parts cannot address: Customized dimensional limits for tight spaces Many miniature automation devices, lab testing equipment, and compact actuator systems have strict spatial restrictions. We fully customize core parameters including screw diameter, overall length, lead, and nut outline size to fit confined installation layouts without sacrificing motion precision. Our MIA mini series specializes in ultra-small diameter micro screw structures ideal for compact machinery. Specialized material matching for harsh working environments Our base material is high-strength GCr15 bearing steel for standard precision applications. For special working conditions such as corrosion exposure, high-temperature operation, or medical clean environments, we support custom material upgrades including stainless steel and high-temperature wear-resistant alloys to extend component lifespan under extreme conditions. Custom load & speed performance design High-load industrial actuators and high-speed precision inspection equipment have divergent motion demands. We redesign the ball circulation track, thread profile, and nut structure for custom ball screws, boosting load capacity, lowering friction, and enabling stable high-speed reciprocating movement for your equipment. Custom manufacturing & surface finishing processes Beyond standard rolling and grinding machining, we provide exclusive custom processing solutions: special thread grinding tolerances (C3/C5/C7 precision grades), customized surface hardening, anti-rust coating, and tailored end-machining features to match your coupling, bearing, and assembly structure perfectly.
