MHL2 Series Wide Opening Parallel Pneumatic Gripper

Brand: SOLH by Richge Technology 

Product Overview

      SOLH MHL2 series is wide-stroke rack & pinion synchronous parallel gripper. Core advantages: powerful clamping force, ultra-wide opening travel, high structural rigidity and versatile mounting options. Suitable for heavy & large workpiece transportation, wide-size part gripping and high-load parallel clamping. Widely adopted in automated loading/unloading, machine tool fixtures and packaging machinery.

Core Structure & Working Principle

     -- Transmission: Rack & pinion mechanism ensures synchronous jaw movement without offset; dual piston layout delivers strong clamping force within compact outline.

     -- Construction: Aluminum alloy body, stainless steel jaws, built-in magnetic ring. All rotating shafts adopt oil-impregnated resin bearings plus integrated dust wiper seals, good dust resistance and extended service life.

     -- Operation Mode: Double Acting (D) only, no single acting variant. Built-in adjustable throttle for smooth speed control. Four magnetic switch mounting slots for flexible position detection layout.

     -- Stroke Selection: 3 standard strokes per bore: D(Short) / D1(Medium) / D2(Long), compatible with outer diameter clamping and inner diameter gripping for various workpiece widths.

     -- Position Accuracy: Repeat positioning accuracy ±0.1mm, stable clamping performance under heavy load conditions.

Stroke & Clamping Force Reference Table (0.5MPa, Standard Clamping Point)

⚠️ Note: Reference clamp distance: 40mm for ø10~25; 80mm for ø32~40. Effective clamping force declines when jaw extension increases. Safety factor ≥1.5 must be reserved during load verification.

Preferred Application Scenarios for MHL2

     -- Heavy / oversized workpieces requiring strong clamping force and wide opening stroke, such as heavy pipes, plates and material trays

     -- Applications demanding synchronous parallel movement without deflection, with flexible multi-direction mounting layout

     -- Dust-prone harsh working conditions (machine tool loading, casting part handling), requiring reliable dust resistance and long service life

     -- Systems needing both outer diameter clamping and inner diameter gripping, compatible with multiple part sizes via 3 stroke options

Key Selection & Application Guidelines

     -- Determine load first before bore selection: Calculate required clamping force based on workpiece weight, jaw extension length and safety factor ≥1.5, then match corresponding bore size.

     -- Select stroke according to workpiece width: Priority sequence D(short) → D1(medium) → D2(long), avoid redundant excessive stroke.

     -- Position detection: Equip with D-M9□ series magnetic switches (NPN/PNP/non-contact) for jaw open/closed feedback; four mounting slots allow flexible arrangement.

     -- Mounting & port configuration: ø10~25 adopt M5×0.8; ø32~40 select Rc1/8 with TN/TF/NPT thread. Choose tapped / through / side mount base according to installation surface.

     -- Dust protection & maintenance: Standard integrated dust scraper. Add -X85/-X86 dust-resistant custom version for heavy dust environments; regularly clean bearings and sealing rings.
