Product Detailed Description：
Our MGPM Series Compact Guided Cylinder is the ultimate solution for applications requiring high precision and anti-rotation performance. Unlike standard cylinders, the MGPM integrates the cylinder body and guide rods into a single aluminum block, significantly reducing space requirements while enhancing structural rigidity.
Available in two bearing types—Slide Bearings (MGPM) for high lateral loads and Ball Bushing Bearings (MGPL) for high-speed, smooth movement—this cylinder is a 1:1 interchangeable replacement for SMC standards. Each unit comes standard with a magnetic piston for easy switch detection and rubber bumpers for noise reduction.
rability, and cost-efficiency.
Product Feature :
1. Integrated Anti-Rotation: Dual guide rods ensure the plate remains stable and resists twisting during extension.
2. High Lateral Load Capacity: The robust slide bearing design is specifically engineered to handle side-impact forces and eccentric loads.
3. Space-Saving Design: Extremely compact axial length allows for installation in narrow machinery pockets.
4. Precision CNC Machined: Hard-anodized aluminum body and high-quality seals ensure zero leakage and long service life.
5. Universal Mounting: Multiple mounting surfaces (top, side, and bottom) provide flexible installation options.

1. Electronics & Semiconductor Assembly (Precision Handling）：
In PCBA (Printed Circuit Board Assembly) and semiconductor testing, the MGPM cylinder acts as the primary actuator for high-speed pick-and-place heads.
The integrated tri-rod structure provides high non-rotating accuracy，ensuring that delicate chips or components are aligned perfectly with the PCB pads. Its compact profile allows it to be mounted in dense arrays on SMT machines where space is at a premium. The ball bushing version (MGPL) is preferred here for its low-friction, jitter-free movement at high cycle rates.
2. Automated Food & Beverage Packaging (Side-Load Diverting)：
Widely used on conveyor sorting lines as a "pusher" or "stopper" to divert bottles, cans, or boxes from one lane to another.
Standard cylinders often suffer from rod bending or seal failure when subjected to the lateral impact of moving products. The MGPM’s Slide Bearing (bushing) is specifically designed to absorb these high eccentric loads and side-impact forces. The hard-anodized aluminum body also offers the necessary corrosion resistance for environments that require frequent wipe-downs.
3. Automotive Body-in-White & Jig Clamping (Structural Rigidity）：
Utilized in welding jigs and assembly fixtures to position car body panels or engine components before robotic welding or bolting.
The structural rigidity of the guide rods ensures that even under the heavy pressure of a clamp, the cylinder will not deflect. This high moment resistance prevents misalignment of the workpiece, which is critical for maintaining the tight tolerances required in modern automotive manufacturing. It serves as a space-saving alternative to using a separate cylinder and external linear guide rail.
Installation and Usage：
1. Precision Mounting: Use the integrated top, bottom, or side holes on a flat surface. Ensure mounting flatness to prevent body distortion or guide rod binding.
2. Speed Control: Always install flow control valves. Maintain piston speeds between 50–500 mm/s to prevent excessive impact and protect internal bumpers.
3. Load Management: Operate within the rated lateral load and moment limits. Avoid eccentric loads that exceed the bearing's capacity to prevent premature wear.
4. Air Quality: Use a 5μm air filter and flush all pipes before connection. The unit is pre-lubricated; if external lubrication is started, it must be maintained.
5. Maintenance: Keep guide rods clean of dust and debris. Avoid applying heavy grease, as it can attract abrasive particles that damage the seals.
6. Sensor Setup: Install auto-switches (sensors) in the built-in grooves for reliable end-of-stroke detection and PLC integration.
FAQ
Q1. What is the difference between MGPM and MGPL?
A1. MGPM uses a Slide Bearing (copper bushing), which is best for high lateral loads and shock resistance. MGPL uses a Ball Bushing Bearing, which is ideal for high-speed applications and smoother linear motion.
Q2. Is this cylinder interchangeable with the SMC MGPM series?
A2.Yes, our MGPM series is designed to 1:1 international standards, meaning the mounting dimensions, port sizes, and performance specifications are fully compatible with SMC models.
Q3. Can I use magnetic sensors with this cylinder?
A3. Absolutely. Every MGPM cylinder is equipped with a magnetic piston as standard, allowing for easy integration with D-M9N, D-M9B, or similar auto-switches.
Q4. Does the cylinder require external lubrication?
A4. No, it is pre-lubricated at the factory with high-grade grease and can operate without additional lubrication. If you start lubricating with an oiler, you must continue to do so.
Q5. What is the theoretical thrust of a 20mm bore at 0.5 MPa?
A5. The theoretical thrust is approximately 157N (approx. 12kg-16kg depending on friction) at an operating pressure of 0.5 MPa.
Q6. Are customized strokes available?
A6. Yes, while we stock standard strokes (10mm to 400mm), we can provide customized stroke lengths to meet your specific machine design requirements.
Q7. How do the guide rods handle lateral loads?
A7.The guide rods are connected to a heavy-duty front plate. The load is distributed through the bearings in the cylinder body, allowing it to handle much higher side loads than a standard rod cylinder.
Q8. What seals are used in the construction?
A8.We use high-quality imported NBR and TPU seals (or Viton upon request) to ensure excellent sealing performance and a wide operating temperature range.
