DFM Three Rods Cylinders

DFM three rod cylinder is a guiding rod cylinder that integrates linear drive and high-precision guidance functions. Its core design integrates the driving unit and guiding structure into a single housing, achieving high rigidity and anti torsion mechanical characteristics through a three rod layout (with the driving piston rod in the middle and the guiding rods on both sides). This cylinder combines a compact structure with strong load capacity, making it suitable for automation scenarios that require precise linear motion and high lateral force bearing, such as clamping, lifting, blocking, and other working conditions.

High load and anti torsion performance

100% increase in effective load: Compared to competitors, the DFM three bar cylinder has an average movable load that is 100% higher, with a maximum lifting capacity of over 200kg, and excellent dynamic performance.

Anti lateral force and torque: The design of large-diameter guide rods and four sliding bearing sleeves (or circulating ball bearing guide rail options) significantly improves rigidity and adapts to high torque load scenarios, such as stamping, die-casting, and other working conditions.

High rigidity structure: The integrated design of the cylinder body and guide unit reduces assembly errors and ensures long-term operation without deformation.

Precise guidance and stability

Dual guide rod structure: The two side guide rods and the middle drive rod form a stable triangular support, eliminating motion deflection and achieving micrometer level positioning accuracy.

Sliding/ball bearing guide rail optional: Sliding bearing guide rail is suitable for low friction, maintenance free scenarios; Ball bearing guide rails support higher torque loads and meet heavy-duty requirements.

Compact Design and Space Optimization

Integrated structure: The driver and guide rail share the same housing design, which shortens assembly time, reduces external connectors, and saves installation space.

Multiple installation methods: Supports multiple installation interfaces such as front/rear flanges, footrests, hinge shafts, etc., flexibly adapting to different device layouts.

Lightweight and high-strength: The cylinder body is made of aluminum alloy material (some models are made of stainless steel), which balances corrosion resistance and lightweight requirements.

Durability and reliability

Maintenance free design: wear-resistant and anti-aging materials are selected for seals to reduce lubrication demand and extend maintenance cycle.

Strong environmental resistance: Suitable for temperatures ranging from -20 ° C to+80 ° C, with optional high-temperature resistant seals (up to 120 ° C), suitable for humid, dusty, and corrosive gas environments.

Impact resistant design: Some models are equipped with hydraulic buffers or adjustable pneumatic buffers (PPV) to effectively absorb braking impacts and protect equipment.

Rich derivative models to meet personalized needs

DFM-B series: supports advanced functions such as precise adjustment of terminal position, hydraulic buffer, ATEX explosion-proof certification, etc., suitable for special scenarios such as lithium-ion battery production and clean rooms.

Special Material Options: Provides corrosion-resistant coatings without copper, zinc, or nickel, meeting the cleanliness requirements of industries such as semiconductor manufacturing.

Automatic production line

Clamping and positioning: used for precise clamping of workpieces before processing, ensuring the stability of assembly, testing and other processes.

Tray stop: Replace traditional mechanical stops, achieve contactless braking, reduce equipment wear, and improve production efficiency.

Logistics conveying system

Goods blocking and diversion: In sorting machines and conveyor lines, efficient diversion of goods is achieved through rapid response.

Lifting and Transfer: Easily transfer loads weighing over 200kg, suitable for automated warehouse stacking scenarios.

Machining equipment

CNC machine tools and machining centers: withstand cutting forces and vibrations, maintain workpiece positioning accuracy, and improve machining quality.

Stamping and die-casting equipment: adapted to high torque loads, ensuring the stability of mold opening and closing.
