The hollow linear shaft is professionally produced by Lishui Hengyuan Bearing Manufacturing Co., Ltd. and is a core transmission component designed specifically for lightweight and high dynamic industrial scenarios. Using high-strength bearing steel, stainless steel or carbon steel materials, combined with precision cold drawing and inner wall polishing technology, the hollow structure of the shaft body ensures rigidity (bending strength ≥ 600MPa) while reducing weight by 40% -60%, suitable for high-speed robotic arms, automated production lines, medical equipment and semiconductor processing machinery and other scenarios. Its unique hollow design supports internal wiring, coolant or gas flow, greatly simplifying equipment structure layout and improving transmission efficiency and functionality.
Specifications and models
Core advantages
Lightweight and high rigidity: Hollow structure design increases bending strength by 20% compared to solid core, reduces weight by 50%, reduces equipment inertia load, and achieves both speed and energy savings
Multi functional integration: The inner hole diameter can be selected from Φ 5mm to Φ 50mm, supporting cable and air pipe passage or coolant circulation, solving the problem of complex equipment wiring and reducing external interference.
Precision motion performance: customized outer diameter tolerance g6 h7, Straightness error ≤ 0.05mm/500mm, surface hard chromium coating (10-30 μ m), friction coefficient as low as 0.002, suitable for smooth operation of linear bearings.
Full scenario weather resistance: Stainless steel models are resistant to acid and alkali corrosion, while carbon steel models are chrome/nickel plated on the surface, suitable for diverse environments such as humidity, high temperature, and clean workshops.
Support customized inner wall polishing (Ra ≤ 0.4 μ m), end processing (threads, flange mounting holes), and special coatings.
