MSUB Series Vane Rotary Cylinder | High Precision Compact Oscillating Cylinder

Brand: SOLH by Richge Technology 

1. Product Overview & Core Structural Features

     The SOLH MSUB series is a high-precision single-vane rotary table cylinder designed for light-load precision oscillating applications. It features an integrated compact structure, fine-tunable swing angle, multi-surface mounting and ultra-low backlash performance. Covering 4 size specifications (corresponding to bore φ10/φ15/φ20/φ30), it is widely applied in manipulator rotation, small indexing positioning and workpiece flipping stations, serving as the mainstream high-precision swing solution for automated precision production lines.

  1.1 Integrated Rotary Table & Cylinder Structure

     Integrated design of rotary platform and driving cylinder eliminates gear clearance completely with enhanced overall rigidity. The standard model achieves ultra-low runout tolerance, while the upgraded MSUA high-precision version delivers platform wobble accuracy within ≤0.03mm, ensuring stable and repeatable precision positioning.

  1.2 High-Load Single Vane Design

     Adopting optimized single-vane structural layout, the cylinder features smaller volume and lighter weight. Its load capacity is 2~3 times higher than traditional CRB1 series cylinders of the same size, realizing miniaturization and high-torque output simultaneously.

  1.3 Precisely Adjustable Swing Angle

     • Standard Stroke: 90° / 180° optional for diverse rotary demands.

     • Fine Adjustment Tolerance: Single-vane design supports ±5° fine tuning at both ends; dual-vane type supports ±2.5° fine tuning.

     • Positioning Accuracy: Strict swing angle tolerance of 90°±10′ / 180°±10′, meeting high-precision indexing and flipping requirements.

  1.4 Flexible Mounting & Piping Options

     • Piping Mode: Side piping and axial piping optional; magnetic switch-equipped models only support side piping for stable signal acquisition.

     • Mounting Mode: Multi-face flange structure supports omni-directional installation, effectively saving equipment internal space and adapting to compact layout scenarios.

  1.5 Low Leakage & Long Service Life

     Adopting customized special sealing structure to minimize internal and external air leakage. Standard oil-free operation design adapts to clean production environments and general industrial working conditions, reducing maintenance costs and extending continuous service life.

4. Core Configuration & Selection Guidelines

  4.1 Size Selection (Based on Torque & Load)

     • Size 1 (φ10): 0.3N·m torque output, suitable for micro ultra-light load (≤1kg) and high-frequency precision rotary motion scenarios.

     • Size 3 (φ15): 0.7N·m torque output, ideal for small light-load (1~3kg) applications such as robotic arm joint rotation.

     • Size 7 (φ20): 0.9N·m torque output, perfectly matching small and medium load (3~5kg) indexing positioning and workpiece flipping stations.

     • Size 20 (φ30): 2.9N·m high torque output, applicable for medium heavy-load (5~10kg) heavy-duty rotary positioning tasks.

  4.2 Angle & Precision Selection

     • 90° Swing Angle: Designed for right-angle flipping and directional switching, widely used in workpiece loading/unloading and 90° steering positioning.

     • 180° Swing Angle: Suitable for half-cycle rotation and workpiece flipping, realizing 180° reverse positioning and bidirectional station switching.

     • High-Precision Upgrade: Choose MSUA series for ultra-high precision requirements with platform wobble accuracy ≤0.03mm.

  4.3 Magnetic Switch Configuration

     • MSUB (Non-Magnetic): Basic economical version without magnetic ring, cost-effective for simple cyclic motion without signal feedback demand.

     • MDSUB (Magnetic): Built-in magnetic ring, compatible with D-T791/D-T792 magnetic switches with arbitrarily adjustable sensing positions, supporting automated PLC signal linkage control.

5. Typical Application Scenarios

     • Precision Robotic Systems: Applied to small robot joint rotation and end-effector swinging, featuring lightweight, compact size and high positioning repeatability.

     • Automated Indexing Stations: Perfect for 90°/180° precision indexing, detection positioning and assembly station positioning in electronics and small home appliance industries.

     • Workpiece Flipping & Steering: Ideal for flipping and direction conversion of light-load workpieces (≤10kg) on conveyor lines, achieving zero-backlash and low-impact smooth rotation.

     • Small Rotary Platforms: Widely used in micro rotating platforms, label printing and marking station rotation, with flexible installation and low maintenance difficulty.
