The design gives equal right- and left-thread lengths by default, with about 20 mm reserved for the middle joint to enhance synchronization between opposing motors. Built for smooth operation and stable axis travel, it’s a solid upgrade for DIY printers and custom builds. The screw uses a 2 mm lead and 8 mm diameter, with stainless steel rods for durability and brass nuts for reliable mounting. Custom lengths and end-machining options are available on request via Amazon message.\u003c\/p\u003e \u003cp\u003e✅ Lead screw diameter: 8 mm (0.315 in) \u003cbr\u003e\n✅ Lead \/ Pitch: 2 mm (0.079 in) \u003cbr\u003e\n✅ Total length: 200 mm (7.87 in) \u003cbr\u003e\n✅ Right\/Left hand thread length: 90 mm each \u003cbr\u003e\n✅ Middle joint reserve: ~20 mm \u003cbr\u003e\n✅ Material: 304 stainless steel rod \u003cbr\u003e\n✅ Nut: 2x brass nuts (T8) \u003cbr\u003e\n✅ Bi-directional with dual nuts for better synchronization\u003c\/p\u003e \u003cp\u003e💡 What is a lead screw used for in precision motion control systems?\nIt's a handy component that converts rotation into controlled linear travel for accurate positioning. - High-precision linear motion for 3D printers, CNCs, and automation. - Reduces backlash with dual-nut arrangements and careful mounting. - 2mm lead provides fine resolution for smooth stepping. - Durable stainless steel screw with brass nuts for long life and easy installation.\u003c\/p\u003e \u003c\/div\u003e","brand":"Amazon","offers":[{"title":"Default Title","offer_id":48077461094635,"sku":"VXB0B711ZD85","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/3268\/0683\/files\/51goQMjNbrL.jpg?v=1775865821","url":"https:\/\/vxb.com\/products\/8mm-lead-screw-200mm-length-bi-directional-with-2","provider":"VXB Bearings","version":"1.0","type":"link"}
