RS2H Series Heavy-Duty Stopper Cylinder | Adjustable Hydraulic Buffer Lever Stop Cylinder

Brand: SOLH by Richge Technology 

1. Product Overview & Core Structural Advantages

     The SOLH RS2H series is a new-generation heavy-duty lever-type stopper cylinder, professionally designed for heavy-load conveyor line positioning and limiting. Available in large bore sizes φ50/63/80mm, it features ultra-high stopping force, adjustable hydraulic buffer, lightweight compact structure and superior impact resistance. Specially applicable for 50–500kg heavy pallets and tooling plates, it serves as the core stopping component for heavy-duty automated conveyor lines, widely used in workpiece stopping, transfer positioning and station limiting scenarios.

  1.1 Upgraded Heavy-Duty Performance

     As an upgraded replacement for the traditional RS1H series, the RS2H achieves a more than 30% increase in stopping force. Adopting a combined lever force amplification and hydraulic buffer structure, it perfectly withstands high-frequency impact loads and stably limits heavy workpieces ranging from 50kg to 500kg, solving the problems of insufficient force and easy failure of old models under heavy-load cyclic operation.

  1.2 Compact & Lightweight Optimization

     Compared with the RS1H series, the φ63-30 stroke model reduces overall weight by 22% and shortens total length by 9mm. The optimized integrated structure saves installation space while improving overall structural rigidity, realizing smaller size, lighter weight and higher stability.

  1.3 Core Adjustable Hydraulic Buffer

     Built-in adjustable hydraulic buffer as standard. Users can freely adjust the damping resistance via the rotating adjustment disc to adapt to workpieces of different weights and conveying speeds. The buffer supports tool-free quick replacement by loosening the M4 set screw, greatly improving on-site maintenance efficiency and reducing downtime.

  1.4 High-Rigidity Lever & Dual Roller Design

     The high-strength lever is equipped with an enhanced internal buffer structure. Two roller material options are available: resin (L) and carbon steel (M), featuring wear resistance and anti-cracking performance. The enlarged roller diameter ensures smooth rolling operation and strong anti-deflection capability, effectively avoiding jamming and eccentric load damage during heavy-load stopping.

  1.5 Fully Interchangeable & Diversified Configurations

     The installation dimensions are completely interchangeable with the traditional RS1H series, supporting direct replacement and upgrade without modifying fixture frames. Optional extended functions include anti-rebound locking mechanism, manual release unlock and lever detection switch, meeting the control requirements of complex heavy-load working conditions.

  1.6 Oil-Free & Long Service Life Structure

     Optional double-acting, spring-loaded double-acting and single-acting modes cover diverse operational demands. The hard chrome-plated piston rod and hard anodized cylinder body deliver excellent wear resistance and impact resistance. The oil-free operation design adapts to clean environments and welding splash-proof working conditions with low maintenance costs and long service life.

4. Core Configuration & Selection Guidelines

  4.1 Roller Material Selection

     • Resin Roller (L): Low noise and anti-scratch to pallet surfaces. Ideal for light/medium loads (50–200kg) and high-speed operation (≤0.5m/s) scenarios, protecting workpieces while ensuring stable stopping.

     • Carbon Steel Roller (M): Ultra-high wear resistance and strong impact resistance. Suitable for heavy loads (200–500kg), high-frequency cycling (≥1000 times/day) and harsh industrial working conditions with long service life.

  4.2 Operation Mode Selection

     • Double-Acting (D): Bidirectional controllable clamping and releasing with maximum stopping force. Optimized for heavy-load and high-frequency start-stop working conditions.

     • Spring-Loaded Double-Acting (B): Automatic release upon power failure, prioritizing equipment and personnel safety. Perfect for dangerous stations and power-off protection scenarios.

     • Single-Acting (T): Spring extend, air compression retract mode. Energy-saving and cost-effective, applicable for light-load and low-frequency stopping scenarios.

  4.3 Optional Heavy-Duty Functional Accessories

     • Locking Mechanism (-XC102): Automatic locking after stopping to prevent workpiece rebound and displacement, suitable for high-speed light-load and anti-shifting stations.

     • Manual Unlock Function: Manually release the lever during power failure or equipment failure, ensuring safe and convenient on-site maintenance.

     • Lever Detection Switch: Detects lever extension and reset status, supports PLC linkage control and automated interlock operation for intelligent production lines.

5. Typical Application Scenarios

     • Heavy-Duty Pallet Conveyor Lines: Specialized for stopping, transfer positioning and anti-shifting of 200–500kg heavy tooling plates in automotive, home appliance and logistics industries, delivering stable heavy-load limiting performance.

     • Welding & Machine Tool Heavy Stations: Applied to heavy-load clamping of welding fixtures, machine tool loading/unloading limiting and heavy mold positioning. The buffer structure resists strong impact and prevents welding slag erosion.

     • Automated Warehousing & Transfer Systems: Used for stereoscopic warehouse pallet stopping, AGV docking positioning and heavy-duty flipping mechanism limiting, featuring stable motion and reliable signal feedback.

     • High-Speed Heavy-Duty Conveyor Lines: Suitable for stopping high-speed (≤0.8m/s) heavy workpieces on roller and belt conveyor lines. The adjustable hydraulic buffer ensures smooth and zero-impact stopping process.

6. 3-Step Quick Selection Guide

     1. Bore Size Selection: Select bore according to workpiece weight and conveying speed. Follow the safety standard: theoretical stopping force ≥ actual load × 2. φ50 for load below 200kg, φ63 for 200–350kg load, φ80 for load above 350kg.

     2. Roller Material Selection: Choose resin roller (L) for light-load and high-speed scenarios; choose carbon steel roller (M) for heavy-load and high-frequency cycling scenarios.

     3. Functional Configuration Selection: Select double-acting (D) + carbon steel roller for heavy-load & high-frequency working conditions; add locking mechanism (-XC102) for anti-rebound requirements; adopt spring-loaded type (B) for safety-priority stations.
