Baomain MAL 20×25 Mini Pneumatic Air Cylinder
The Baomain MAL 20×25 is a compact single-acting cylinder designed for tight spaces. It features a 20 mm bore with a 25 mm stroke and a single rod. The aluminum body provides lightweight strength, while standard 1/8″ PT ports enable easy integration with common pneumatic fittings. The piston rod measures 8 mm, supporting reliable, precise linear motion in automation tasks with limited footprint. This model is well-suited for small pick-and-place, clamping, and positioning applications where space is at a premium.
INTBUYING Air Cylinder SC 100 x 450
The INTBUYING SC 100 x 450 cylinder offers a large 100 mm bore with a 450 mm stroke, enabling extended linear travel. Constructed from aluminum alloy, it emphasizes durability and resistance to corrosion in industrial environments. It is a double-acting design with a single-rod piston and a piston port size of M20X1.5, delivering adjustable speeds in a broad range (50–800 mm/s). Its high-temperature tolerance and robust construction support prolonged life in production lines requiring frequent extended strokes and high-duty cycles.
VIILOCK Pneumatic Air Cylinder 32×200
VIILOCK’s 32×200 bore and stroke offer a balanced option for mid-range automation tasks. The aluminum alloy construction provides a durable, lightweight frame, while standard 1/8″ PT ports ensure straightforward piping and compatibility with existing systems. The cylinder supports reliable, repeatable extension and retraction in production lines, fixtures, and automation modules where space permits a slightly larger bore for greater force output than smaller micro cylinders.
TAILONZ PNEUMATIC 10mm Bore 15mm Stroke
The TAILONZ single-acting micro cylinder uses a 10 mm bore with a 15 mm stroke. It employs a copper-nickel plating for the rod and features an external thread for straightforward mounting. This compact option prioritizes simplicity and space savings, suitable for micro-action tasks, precise positioning in limited spaces, or actuator integration in compact automation setups where only light travel is required.
HNJPC SC Air Cylinder 40×100
The HNJPC SC 40×100 cylinder provides a 40 mm bore with a 100 mm stroke in a robust aluminum body. It features a double-acting design with PT1/4 threads and is built to operate within a typical industrial air pressure range. Its broader bore yields higher force output, making it suitable for applications requiring stronger push actions, clamp mechanisms, or material handling where a compact but powerful cylinder is needed in automation lines.
Baomain MAL 32×250 Mini Pneumatic Air Cylinder
The Baomain MAL 32×250 combines a 32 mm bore with a lengthy 250 mm stroke, delivering extended travel in a compact body. The unit uses a single rod and aluminum construction with 1/8″ PT ports for easy integration with standard pneumatic fittings. Its larger stroke is beneficial for applications requiring extended reach, longer feed paths, or spacing between workpieces in automated lines where space is constrained but travel distance is essential.
Buying Guide: Key Purchase Considerations
- Application requirements: Determine the required bore (for force) and stroke (for travel) to select a cylinder that meets load and distance needs without overbuying size and weight.
- Action type: Choose single-acting for simple push-only extension with external return or a double-acting option when both extension and retraction are needed with consistent force in both directions.
- Mounting and ports: Verify port size (PT or metric) and mounting standards (clevis, foot, flange) to ensure compatibility with existing hardware and fittings.
- Material and build: Aluminum bodies are lightweight and corrosion-resistant; stainless variants offer better protection in harsh environments. Rod plating (chrome, copper-nickel) affects wear resistance and longevity.
- Operating environment: Consider temperature and pressure ranges, especially in high-temperature or high-dust settings, to select a cylinder that maintains performance and longevity.
- Maintenance and availability: Look for cylinders with common seal kits and readily available spare parts to minimize downtime.
- Cost vs. lifecycle: While compact micro cylinders may be cheaper upfront, larger bore and longer strokes can offer better performance in industrial cycles, reducing cycle times and increasing throughput over time.
- Compatibility: Ensure the cylinder’s port thread, mounting style, and rod diameter align with your existing pneumatic system and actuators to avoid adapters or redesigns.
Comparison At a Glance
- Small, compact options (20–32 mm bore) excel in tight spaces and light automation tasks with straightforward control and installation.
- Medium-to-large bores (40–100 mm) provide higher push forces for clamping, lifting, or translating heavier loads.
- Stroke length is critical for reach; longer strokes increase reach but add volume and weight that may require more mounting support.
- Material choice impacts longevity in dusty or corrosive environments; aluminum is common, while stainless or plated rods boost durability.
- Port sizing and thread standards affect ease of integration with existing pneumatic manifolds and fittings.
For American manufacturers and integrators, selecting the right single acting air cylinder involves balancing space, travel, force, and maintenance considerations. The products listed here span compact micro options to mid-size configurations, addressing a broad range of automation tasks from precise micro-actuation to longer travel in compact frames. Always verify compatibility with your system’s air supply, control valves, and mounting hardware before finalizing a purchase.
