HFR Series 180° Pivot-Type Wide Opening Pneumatic Gripper

Brand: SOLH by Richge Technology

Product Overview

     SOLH HFR series is pivot-linkage driven 180° wide-opening 2-jaw pneumatic gripper. Core strengths: full 180° jaw opening for maximum clearance, excellent mechanical avoidance capability, three universal mounting surfaces, integrated dust-proof structure and pre-installed permanent magnet. It is the mainstream actuator choice for light-load stations requiring large swing clearance to eliminate pick-and-place interference and wide-range workpiece gripping.

Core Structure & Working Features

     -- Operating Principle: Piston pushes pivot linkage assembly to drive two jaws for rotary movement. Single jaw swing angle reaches 90°, jaws form straight line when fully opened to maximize avoidance space.

     -- Action Characteristic: Double acting as standard; air supply for clamping, reverse air for opening. Max open angle 180°±2°, overclose angle -2°~-5° for stable positioning.

     -- Dust & Wear Protection: Optimized dust-proof structure at jaw section for dusty environments. Metal separator plates isolate friction surfaces to reduce abrasion and extend service life.

     -- Flexible Mounting: Three mounting faces (side / bottom / rear). Locating pin holes on bottom base improve assembly accuracy and repeat positioning consistency.

     -- Sensor Compatibility: Permanent magnet equipped for all specifications. Circular sensor grooves on side walls support direct installation of CMSH/DMSH(S) magnetic switches without extra brackets.

Core Competitive Advantages

   1. 180° ultra-wide opening for complete mechanical avoidance

     -- Jaws align in straight line at full stroke, delivering maximum clearance to solve workpiece interference issues, ideal for deep cavity & narrow opening component picking.

   2. Lightweight efficient pivot linkage structure

     -- Simplified linkage design reduces body weight by 15% vs equivalent parallel grippers, fast response suitable for high-frequency light-load cycles.

   3. Dust-proof & wear-resistant for harsh workshop conditions

     -- Special jaw sealing prevents debris ingress; anti-friction metal separators ensure cycle life ≥5 million times.

   4. Three-side mounting plus locating pins for easy commissioning

     -- Multi-orientation mounting holes together with bottom locating pins enable fast centering and consistent repeat positioning for complex tooling layout.

   5. Built-in magnet, ready for sensor installation

     -- Standard integrated permanent magnet and dedicated slide grooves eliminate extra mounting fixtures, saving component cost and assembly time.

Mounting Forms & Typical Industrial Applications

   1. Mounting Options

   -- Side mounting: Horizontal wide-opening gripping for wide-size workpiece transfer on assembly lines

   -- Bottom mounting: Vertical lifting plus avoidance movement for deep cavity mold & container picking

   -- Rear mounting: Lateral clearance gripping for confined stations prone to mechanical interference

   2. Typical Application Scenarios

     -- 3C & Electronics: Gripping mobile middle frames, battery compartments and large plastic housings

     -- Automotive Components: Transfer of lamp shells, interior panels and large rubber parts

     -- Packaging & Logistics: Avoidance picking of large cartons, pallets and bagged materials

     -- General Automation: Loading/unloading, turnover and assembly stations requiring 180° clearance

3-Step Fast Selection Guide

   1. Bore selection based on workpiece mass and gripping torque

     -- 10 ≤0.5kg；16 =0.5~1kg；20 =1~2kg；25 =2~3kg；32 =3~5kg. Reserve ≥30% safety margin.

   2. Swing stroke confirmation

     -- Choose HFR if full 180° clearance avoidance is required; select MHW2 if only wide-angle clamping without severe interference.

   3. Configuration matching

     -- PLC interlock control: Install two CMSH switches to monitor fully open & closed status.

     -- Mounting requirement: Standard version with locating pins for bottom positioning; select suffix N for through-hole installation.

One Sentence Summary

     SOLH HFR pivot-type 180° wide opening pneumatic gripper adopts linkage swing mechanism with full 180° jaw clearance, three-side mounting, dust-proof construction and built-in magnet; preferred light-load actuator for automated pick-and-place, turnover stations requiring large mechanical avoidance space in 3C, automotive and packaging equipment.
