MSQ Series Rack & Pinion Rotary Actuator Table (SOLH Richge Technology)

Brand: SOLH by Richge Technology 

Product Overview

     SOLH MSQ series adopts dual piston symmetrical rack & pinion driving structure, split into two sub-series: MSQB standard grade and MSQA high precision grade. It features integrated circular mounting table with central hollow through hole, swing angle continuously adjustable from 0~190°.

Symmetric dual piston rack-pinion delivers 3~4 times larger output torque and superior radial/axial load capacity compared with vane-type CRQ rotary cylinders. Two shock absorption options available: built-in rubber buffer or integrated hydraulic buffer. Dual air port layout (end face / side front) simplifies tubing layout; compatible magnetic reed switches for rotary position signal feedback. Widely used for automated indexing, workpiece flipping and precision positioning stations.

     -- L / H: Hydraulic buffer kinetic energy grade (only for R hydraulic version)

        L = Low kinetic energy hydraulic buffer; H = High kinetic energy hydraulic buffer

     -- Digit 2/3/4/5: Fixed swing angle specification

        2 = Standard 180°; 3 = 90°; 4 = Symmetric 180°; 5 = Symmetric 90°

     -- Middle box: Custom marking X, blank = standard stock model

     -- M9BW: Magnetic switch, blank = no sensor equipped

     -- Penultimate box: Magnetic switch quantity; blank=2pcs, S=1pc

     -- Last box: Air port thread specification

        Blank = M5 thread (only for size 10/20); XF = G1/8; XN = NPT1/8 American thread

Core Structural Advantages

  1. Symmetric Dual Piston Rack & Pinion Drive

     -- Dual synchronous pistons push gear synchronously, eliminating unilateral backlash; uniform torque output with zero rotation jitter, far higher load capacity than single-piston vane cylinders.

  2. Integrated Rotary Table with Locating Pin Holes

     -- Table pre-machined positioning pin holes and standard mounting tapped holes for direct jig/workpiece locking, easy alignment and high integral rigidity. Central hollow through hole (φ6~φ24) allows air tubing and sensor wiring to pass through center, neat internal machine layout.

  3. Dual Air Port Layout

     -- Two piping options: end face air inlet or side front E-type port, flexible tubing routing for compact confined equipment without mechanical interference.

  4. Independent Dual-End Angle Adjustment Screws (Suffix A)

     -- Separate limit screws on both ends to independently restrict clockwise and counter-clockwise stroke; swing range infinitely adjustable within 0~190°, factory default preset to 190°.

  5. Two Optional Shock Absorption Systems

     -- Standard version: Dual-end rubber bump buffer for noise reduction under low-speed light load

     -- -R hydraulic buffer version: Integrated oil shock absorber (L low kinetic / H high kinetic grades) absorbs heavy impact at high speed, minimizes stop vibration and protects fixtures & workpieces

  6. Magnetic Position Feedback Compatible

     -- Built-in permanent magnetic ring inside cylinder body, compatible with M9BW / M9BL reed switches to transmit 0°/90°/180° in-place signals to PLC for automatic interlock logic.

  7. Precision Ball Bearing Support for MSQA

     -- MSQA high-precision model adopts class precision ball bearing assembly; radial & axial runout ≤0.01mm, repeat positioning accuracy ±0.01mm. MSQB basic version meets general automation positioning requirements.

Universal Standard Technical Specifications

  1. Drive Mode: Double acting dual piston rack & pinion

  2. Operating Pressure Range

    -- Rubber buffer type: 0.1~1.0 MPa

     -- -R hydraulic buffer type: 0.1~0.6 MPa

  3. Proof Test Pressure: 1.05 MPa

  4. Ambient Temperature: 0~60℃ (no ice inside air circuit)

  5. Adjustable Swing Range: 0~190° infinitely adjustable, factory preset 190°; fixed angle 90° / 180° optional

  6. Lubrication: Pre-filled long-life grease at factory, lubrication-free design compatible with oil-free clean dry air

  7. Applicable Medium: Filtered dry compressed air (≥40μm filtration precision)
