YIDI MOTION Unveils HM90B Sealed Ball Screw Linear Module

The HM90B is a fully integrated, double-shaft linear stage housed within a 90 mm-wide sealed aluminum extrusion. Its enclosure protects the internal ball screw, linear guide rails, and bearing blocks from dust, metal chips, cutting fluid, and other airborne contaminants—extending service life and maintaining positioning accuracy over time in demanding production environments. The module accepts a NEMA 23 (57 mm) stepper motor as standard and is offered with three C7-grade flanged ball screw options: 1204 (12 mm diameter, 4 mm lead), 1605 (16 mm diameter, 5 mm lead), and 1610 (16 mm diameter, 10 mm lead), each with dust-proof and rust-proof treatment.

At a maximum running speed of 300 mm/s, the HM90B supports a horizontal load of up to 50 kg and a vertical load of up to 20 kg. Its dual-track bearing-steel linear guide design eliminates longitudinal clearance, ensuring smoother operation and greater load capacity compared with single-rail alternatives. The sliding platform features six M6 mounting holes on a 115 × 100 mm pattern, while the base provides four Ø5.2 mm mounting holes and movable M6 T-nuts for flexible limit-switch installation.

• Fully Enclosed Dust-Proof Housing: The sealed aluminum extrusion body isolates the ball screw and linear guides from dust, metal chips, and contaminants, ensuring long-term accuracy and reliability in harsh industrial settings.
• C7-Grade Precision Ball Screw: Flanged-nut ball screw with accuracy up to 0.05 mm, available in 1204, 1605, and 1610 specifications—all with dust-proof and rust-proof surface treatment.
• Dual Bearing-Steel Linear Guides: Double-shaft, dual-track drive eliminates longitudinal clearance, improves overall stability, enhances bearing smoothness, reduces noise, and increases load capacity.
• Movable Nut System: Side-mounted M4 nuts can be installed at any position along the rail; bottom M6 movable T-nuts on the sliding platform enable flexible and convenient limit-switch mounting.

• High Precision: C7-grade ball screw and dual linear guides deliver ±0.03 mm repeat positioning accuracy for consistent, reliable motion.
• Silent and Smooth Operation: Dual-track bearing-steel guides and precision ball screw ensure low-noise, vibration-free travel across the full speed range.
• Durable Construction: Sealed aluminum housing with dust-proof and rust-proof treatment protects internal components, extending service life in harsh environments.
• Strong Load-Bearing Capacity: Supports up to 50 kg horizontally and 20 kg vertically, suitable for heavy-duty automated loading/unloading and material handling.
• Easy Installation: Pre-assembled and pre-aligned module with movable M4/M6 nuts, standardized mounting patterns, and flexible limit-switch placement reduces setup time.
• Manufacturer Warranty & Fast Shipping: Backed by direct-from-manufacturer quality assurance and flexible logistics, with customizable stroke lengths and invoicing support.
