Engineers, makers, and CNC hobbyists working on motion-sensitive assemblies rely on all-plastic linear shaft bearings to keep their systems running quietly and cleanly — without the maintenance headaches of steel.\u003c\/p\u003e\n    \u003cp\u003eThese RLM-01 series nylon linear shaft bearings are machined from engineering-grade nylon (PA66 or equivalent), offering a self-lubricating, corrosion-resistant sliding surface. Available in bore sizes from 6 mm (0.24 in) to 30 mm (1.18 in), they are designed to fit standard metric linear shafts across the full RLM-01-06 through RLM-01-30 model range. Each unit is a single-piece all-plastic construction — no metal inserts, no rust, no conductivity.\u003c\/p\u003e\n    \u003cp\u003eTypical use cases include low-noise 3D printer Z-axis carriages, CNC router gantry slides requiring non-magnetic components, laboratory automation linear stages where corrosion resistance is critical, and DIY robotics joints needing lightweight reciprocating motion.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"hdiy-compat\"\u003e\n    \u003cspan class=\"hdiy-compat-icon\"\u003e⚙️\u003c\/span\u003e\n    \u003cstrong\u003eCompatibility:\u003c\/strong\u003e Fits standard metric linear shafts — 6 mm, 8 mm, 10 mm, 12 mm, 16 mm, 20 mm, 25 mm, and 30 mm diameter.
