MK Series Rotary Clamp Cylinder | 90° Rotation & Linear Clamp 2-in-1 Pneumatic Cylinder

Brand: SOLH by Richge Technology 

Product Overview & Core Structural Features

     The SOLH MK series is a standard 2-in-1 rotary clamp cylinder integrating 90° rotation and linear clamping motion. It covers bore sizes from φ12mm to φ63mm with standard clamping strokes ranging from 5mm to 50mm. Featuring ultra-compact installation, 3 times upgraded allowable inertia torque, 4-side magnetic switch mounting and optional left/right rotation, this cylinder is ideal for space-constrained automated stations for workpiece positioning, clamping and fixing, serving as a core pneumatic component for standard automated fixture systems.

1. Compound Rotation & Clamping Motion

• Working Sequence: Retract → 90° left/right rotation → extend for clamping; Reverse sequence: Retract to release clamp → reverse 90° rotation → extend for reset.

• High-Precision Positioning: Fixed 90° rotation angle with ±5° tolerance, delivering excellent anti-rotation performance and reliable repetitive positioning accuracy.

2. Upgraded High Load Capacity

• 3X Higher Inertia Torque: The new upgraded MK series triples the allowable inertia torque, matching the heavy-load performance of traditional MK2 series, perfectly adapting to high-speed operation and large-inertia workpiece clamping scenarios.

• Powerful Clamping Force: The maximum φ63 bore model provides a strong clamping force up to 12.4kN at 0.5MPa, ensuring stable and firm clamping for heavy-duty applications.

3. Compact Body & Flexible Multi-Directional Installation

• Slim & Shortened Structure: Ultra-thin body design with overall length 3~10mm shorter than conventional MK2 cylinders, greatly improving space utilization for narrow and compact equipment layouts.

• Multi-Side Switch Mounting: Supports 4-side magnetic switch installation (φ20/φ25 for 2-side only). Embedded switch design avoids external exposure and interference, enabling flexible and tidy circuit layout.

• Universal Mounting Method: Equipped with through holes and double-end threaded holes, compatible with direct fixed mounting and flange mounting to meet various assembly requirements.

4. Reliable & Durable Performance

• Stable Buffering: Double-acting structure with bilateral rubber buffers effectively reduces operating impact, vibration and running noise for long-term stable cyclic operation.

• Oil-Free Operation: Adopts professional oil-free lubrication design, suitable for dust-free and clean working environments.

• Standard Magnetic Configuration: Built-in magnetic ring with reserved mounting grooves for magnetic switches, convenient for stroke position detection.

Typical Application Scenarios

• Workpiece Positioning & Clamping: Widely used for machine tool fixtures, welding positioning, stamping fixing and assembly station clamping. The integrated 2-in-1 rotation and clamping design simplifies mechanical structure and saves installation space.

• Electronic & Precision Component Fixing: Oil-free and low-dust characteristics perfectly suit semiconductor tray clamping, phone shell positioning and micro precision part fixing, meeting high cleanliness and high-precision requirements.

• Automated Transfer Limiting: Ideal for rotary table limiting, flipping mechanism positioning and short-stroke rotary clamping stations, delivering stable and repeatable compound motion performance.

• Heavy-Duty Fixing Stations: Equipped with high clamping force and excellent anti-deflection capacity, it is applicable for heavy workpiece clamping, mold fixing and large-load precision positioning scenarios.

3-Step Quick Selection Guide

1. Bore Size Selection: Select bore size according to actual clamping load. Ensure the theoretical clamping force ≥ actual load × 1.5 safety factor; prioritize φ40 or larger bore for heavy-duty working conditions.

2. Stroke Selection: Standard clamping stroke ranges from 5mm to 50mm. Select stroke based on actual workpiece height, and reserve 3~5mm margin to avoid mechanical interference.

3. Configuration Selection

￮ Rotation Direction: Choose RZ (clockwise right rotation) or LZ (counterclockwise left rotation) to match on-site station layout.

￮ Position Detection: Select 2S dual-switch configuration to acquire dual position signals for clamping and releasing status.
