RSQ Series Stopper Cylinder | Fixed Mounting Height Pneumatic Stop Cylinder

Brand: SOLH by Richge Technology

1. Product Overview & Core Structural Features

     The SOLH RSQ series is a fixed mounting height stopper cylinder designed for automated conveyor line positioning and workpiece limiting. It covers bore sizes from φ12mm to φ50mm with standard strokes ranging from 10mm to 30mm. Featuring fixed-height rigid structure, built-in buffer, 10 optional rod end types and 4-side magnetic switch mounting, the RSQ cylinder delivers low-cost and high-reliability stopping solutions for conveyor station blocking, pallet positioning and workpiece limiting, serving as a standard core component for automated conveying systems.

  1.1 Fixed Height Rigid Structure

     Different from the height-adjustable RSG series, the RSQ series adopts a non-adjustable fixed mounting height design. It features a simpler structure, higher overall rigidity and faster on-site installation, perfectly matching fixed-height station layouts and eliminating height calibration procedures.

  1.2 Versatile Multi-Rod-End Adaptation

     Equipped with 10 types of rod end options, including round rod, bevel cut, roller and lever structures, fully covering light, medium and heavy load stopping scenarios. Lever types (L/B/C/D/E) adopt built-in hydraulic buffer design with excellent energy absorption and strong impact resistance for high-frequency and heavy-impact working conditions.

  1.3 Flexible Installation & Switch Layout

     The cylinder body supports 4-side magnetic switch installation (compatible with D-A9□/M9□/P3DWA series switches) without extra mounting accessories. Two standard mounting methods are available: B-type through-hole mounting (standard) and A-type double-end threaded hole mounting, adapting to various equipment frames and installation spaces.

  1.4 Oil-Free & Long Service Life Design

     Optional double-acting, spring-return double-acting and single-acting (spring extend) modes meet diverse action requirements. Standard rubber buffer ensures stable operation. The piston rod adopts hard chrome plating treatment, and the cylinder body undergoes hard anodizing process, achieving outstanding wear resistance and impact resistance. The oil-free operation design adapts to clean and dust-free working environments with low maintenance costs.

4. Rod End Types & Applicable Scenarios

5. Typical Application Scenarios

     • Assembly Line Stopping: Applied to pallet stopping, station positioning and anti-shifting for electronic and home appliance assembly lines. The fixed-height design perfectly matches standard conveyor line layouts.

     • Conveyor Line Limiting: Suitable for workpiece stopping on belt and roller conveyors, transfer station positioning, and diverging/merging line blocking. Multiple rod end options adapt to various load grades.

     • Automated Processing Stations: Ideal for machine tool loading/unloading limiting, packaging machine positioning and inspection station stopping, delivering stable and anti-interference cyclic operation.

     • Heavy-Duty Stopping Scenarios: Used for heavy pallet and tooling board stopping, welding station positioning. The hydraulic buffer lever type effectively resists strong impact and high-frequency vibration.

6. 3-Step Quick Selection Guide

  1. Bore Size Selection: Select bore according to actual stopping load. Follow the rule: theoretical stopping force ≥ actual load × 2 safety factor. φ16~φ20 for light load, φ32 for medium load, φ40~φ50 for heavy load.

  2. Stroke Selection: Standard stroke ranges from 10mm to 30mm. Reserve 5~10mm extra stroke margin based on workpiece height to avoid mechanical interference.

  3. Rod End Selection

￮ Light load & low speed: Choose round rod or bevel cut type

￮ High speed & light load: Choose roller type

￮ Heavy load & high-frequency impact: Choose hydraulic buffer lever type (B/C/D/E)
