Double Rod Type Dual Rod Cylinder

 

1. Superior Lateral Load Stability Without External Guides

The built-in dual piston rod guiding structure reinforces anti-torsion and anti-deflection performance. Unlike ordinary cylinders that rely on external slide rails, the STM slide pneumatic cylinder achieves high rigidity and stable positioning independently, avoiding positioning deviation caused by loose guide installation or long-term wear.

2. Dual Mounting Styles for Flexible Installation

This compact slide cylinder supports two practical mounting configurations to match different mechanical designs. The STMB type features a fixed cylinder body with a moving slide platform, while the STMS type adopts a fixed slide structure with a movable cylinder body. Both styles greatly improve layout flexibility for automated machinery.

3. Customizable Cushioning for Smooth Operation

Standard STM pneumatic slide cylinders come with durable rubber bumpers for conventional low-speed and light-load scenarios. For high-speed cycling or heavy-load applications that require reduced end-stroke impact, the optional hydraulic cushion effectively decelerates the platform, lowers mechanical vibration, and extends equipment service life.

4. High-Temperature Resistant Custom Option

Custom high-temperature configurations allow the STM dual rod slide cylinder to operate steadily in harsh environments up to 150°C. Specialized sealing materials and structural upgrades replace standard components to adapt to continuous high-temperature working conditions.

5. Precise Position Feedback for Automatic Control

Compatible with DMSG, CMSG, and EMSG magnetic sensors, the STM slide pneumatic cylinder supports real-time position signal output, seamless connection with PLC systems, and highly repeatable automated cycle control.

The STM slide pneumatic cylinder is widely adopted in precision automation scenarios that require stable linear positioning and repeated pushing motion:

• Industrial automation: Automatic feeding, workpiece positioning, material pushing, sorting, and handling systems

• Pick-and-place equipment: Component transfer, loading and unloading, and precision workpiece displacement

• Packaging machinery: Product positioning, feeding, stopping, and packaging auxiliary mechanisms
• Electronics precision assembly: Compact-space automated assembly, inspection fixtures, and micro-positioning equipment

 

 

• Bore size: Select according to actual load weight and required thrust; larger bore sizes provide stronger output force under the same working pressure
• Stroke length: Choose standard stroke specifications based on mechanical travel requirements; confirm standard/maximum/permissible stroke limits before ordering
• Mounting type: Select STMB for fixed cylinder body installation; choose STMS for fixed slide platform installation
• Cushion configuration: Rubber bumpers suit low-speed and light-load operation; upgrade to hydraulic cushion for high-speed cycling and heavy-load working conditions
• Position sensing: Equip DMSG, CMSG, or EMSG magnetic switches if automatic position feedback and PLC linkage are required
• High-temperature working: Custom high-temperature versions are required for environments above 70°C to ensure sealing stability and service life

 

Q1: What is the difference between STMB and STMS?

A1: STMB refers to body-fixed mounting where the slide platform moves independently. STMS adopts slide-fixed mounting where the cylinder body moves back and forth. Users can select the type according to mechanical fixing requirements.

 

Q2: Can the STM slide cylinder bear lateral loads?

A2: Yes. The symmetrical dual-piston-rod structure greatly improves anti-torsion and anti-deflection capacity compared with single-rod cylinders. Actual allowable lateral load depends on bore size, installation method, and load direction.

 

Q3: Is hydraulic cushion optional?

A3: Yes. Standard models use rubber bumpers. Hydraulic cushioning is optional to reduce end-stroke impact, suppress vibration, and adapt to high-speed and heavy-load cycles.

 

Q4: Does STM support high-temperature working conditions?

A4: Custom high-temperature configurations support continuous operation up to 150°C, adopting special heat-resistant seals and materials different from standard models.

 

Q5: Can magnetic sensors be installed for automatic control?

A5: Yes. The STM slide pneumatic cylinder reserves installation positions for DMSG, CMSG, and EMSG magnetic switches, realizing real-time position detection and automated system linkage.
