MHW2 Series 180° Rack & Pinion Swing Pneumatic Gripper

Brand: SOLH by Richge Technology 

Product Overview

     SOLH MHW2 series is rack & pinion driven 2-jaw swing gripper with total 180° opening angle. Core strengths: precise gear synchronous movement, ultra-wide 180° swing angle, space-saving outline, four-side sensor mounting slots and dust-proof durable construction. Widely adopted for workpiece flipping, loading/unloading, large-size part gripping and confined-space stations, and becomes mainstream selection for large-angle swing gripper applications.

Core Structure & Design Features

     -- Working Principle: Cylinder pushes rack to drive pinion for synchronous rotation; two jaws swing symmetrically. Gear meshing ensures excellent synchronization, uniform clamping force without offset deviation.

     -- Swing Characteristic: Each jaw rotates up to 90°, total bilateral opening 180°. Fully opened jaws stand perpendicular to cylinder body, occupying minimum projection space, ideal for material handling requiring mechanical avoidance.

     -- Body Layout: Square hard anodized aluminum housing with built-in magnetic ring. Four-side (top/bottom/left/right) sensor grooves support direct fitting of M9B / A93 magnetic switches, unrestricted sensor arrangement.

     -- Material & Protection: Hard oxidation cylinder, high-strength alloy steel jaws and dust-proof sealing structure. Narrow clearance prevents foreign matter intrusion, stable performance under dusty workshop conditions and extended service life.

     -- Operation Mode: Double acting (D). Bidirectional cylinder thrust drives forward/reverse gear rotation to realize jaw opening and closing.

Core Competitive Advantages

  1. 180° ultra-wide swing angle & excellent space utilization

     -- Jaws stand vertical to body at full opening, only occupying cylinder projected space, suitable for narrow stations and process requiring workpiece avoidance & flipping movement.

  2. High precision gear synchronous transmission

     -- Rack & pinion meshing drive, synchronous error ≤0.1°, balanced symmetrical clamping, effectively prevents workpiece slipping caused by unilateral force.

  3. 360° flexible sensor layout

     -- Magnetic switches can be mounted on four body surfaces to achieve all-direction position monitoring, convenient installation and commissioning for any mounting orientation.

  4. Dust-proof structure for harsh environment

     -- Optimized sealing and small internal gap block dust ingress; mechanical service life ≥5 million cycles, stable for long-term high-cycle automated production lines.

 Mounting Forms & Typical Industrial Applications

  1. Mounting Options

     -- Axial horizontal mounting: Horizontal clamping for assembly line loading & unloading

     -- Longitudinal vertical mounting: Vertical lifting for workpiece flipping stations

     -- Lateral side mounting: Side clamping for narrow confined equipment space

  2. Typical Application Scenarios

     -- Electronics & Home Appliance: Gripping and flipping housings, panels and large-size components

     -- Automotive Parts: Transportation of lamp housings, interior trims and small castings

     -- Logistics & Packaging: Handling boxes, pallets and barreled materials

     -- Machine & Injection Molding Automation: Picking large workpieces from machine tools and molding machines

Selection Comparison: MHW2 Gear Swing VS MHY2 Cam Swing VS MHT2 Toggle Gripper

3-Step Fast Selection Guide

  1. Bore selection based on workpiece mass

     -- 20 ≤ 3kg；25 = 3~5kg；32 = 5~10kg；40 = 10~15kg；50 = 15~20kg. Reserve ≥30% load safety margin.

  2. Swing angle verification

     -- Standard single jaw swing angle 90°, total opening 180°. Confirm sufficient clearance to accommodate workpiece dimension and avoidance travel.

  3. Configuration matching

     -- Position signal feedback: Utilize four-side mounting slots with M9B series magnetic switches for flexible layout regardless of installation orientation.

     -- Dusty workshop environment: Prioritize MHW2 due to superior dust-proof sealing structure.

One Sentence Summary
