YIDI MOTION, a manufacturer of linear motion modules and positioning solutions, today announced the H300BD dual-slide ball screw linear module. Engineered for heavy-load automation, the H300BD combines a dual linear guide rail architecture with a precision ball screw in a one-piece aviation-grade aluminum body, delivering up to 500 kg of horizontal payload and repeat positioning accuracy of ±0.03 mm across strokes up to 3000 mm.

Engineered for Heavy Loads and Long Strokes

The H300BD is built around two parallel linear guide rails that flank a central precision ball screw. This dual-rail configuration provides exceptional operational accuracy and significantly greater load capacity compared with single-rail designs. The extrusion housing is formed from aviation-grade aluminum using integrated stamping technology, making the body resistant to rust and corrosion with high structural stability. Its brushed and polished surface resists dirt accumulation for clean operation in industrial environments.

Key Features and Benefits

· Dual linear guide rail system delivers higher running accuracy and greater load capacity, supporting up to 500 kg horizontal and 200 kg vertical payload.

· Aviation-grade one-piece aluminum extrusion body provides rigidity, corrosion resistance, and a brushed surface that stays clean.

· C7-class precision ball screw with front and rear end machining accuracy up to ±0.05 mm; available in five lead configurations — 2005, 2010, 2020, 2505, and 2510 — to match speed and thrust.

· Dust-proof and quiet operation; the sealed option protects the screw and rails from chips, dust, and coolant in harsh shop environments.

· Smooth and fluent travel with stable operation; available in motorized and manual hand-wheel versions to suit automated and setup applications.

· Fully customizable stroke, motor mounting, and screw specification to fit specific machine requirements.
