Installation is straightforward in standard fixtures or custom tooling projects requiring robust, corrosion-resistant actuation.
SMC NCMC075-0400 Stainless Steel Cylinder
SMC’s NCMC075-0400 is a stainless steel, round-body double-acting cylinder with a 3/4″ bore and a 4″ stroke. It includes a rear pivot mounting and is designed for linear applications where corrosion resistance and reliable repeatable motion are essential. Notably, it uses a stainless steel body to resist scaling and corrosion in demanding environments, complementing automation cells, fixtures, and tooling setups requiring sturdy actuation.
Hyuduo Heavy Duty Stainless Steel Vane Type Rotary Cylinder
Note: While primarily a rotary cylinder, this model illustrates the breadth of stainless steel pneumatic options available for automation. It features a stainless steel build and a vane-type design that supports rotation and angular motion. Suitable for rotary indexing, valve actuation, or end-of-arm tooling where a robust stainless core is needed. Consider compatibility with your system’s mounting and duty cycle requirements.
Hilitand CDJ2B10-30B Stainless Steel Cylinder
The Hilitand CDJ2B10-30B is a 10 mm bore, 30 mm stroke stainless steel cylinder designed for double-acting operation. It emphasizes quiet operation and space-efficient design suitable for automation lines, packaging machinery, and assistive robotics. It supports a broad temperature range and offers robust corrosion resistance for long service life in demanding environments.
Buying Guide: Key Considerations For Stainless Steel Pneumatic Cylinders
- Material and corrosion resistance: Look for cylinders with stainless steel bodies and chrome-plated rods if applicable to resist rust, washdown, and chemical exposure common in manufacturing environments.
- bore and stroke: Choose the bore size to provide the required force, and the stroke length to achieve the needed travel within your equipment’s working envelope.
- Port size and compatibility: Ensure port type (such as M5 vs larger) matches your air supply fittings. Smaller ports save space but may constrain flow in high-speed cycles.
- Actuation type: Double-acting cylinders enable pushing and pulling actions and are common in automation; single-rod designs offer compact profiles for limited spaces.
- Operating pressure: Confirm the maximum operating pressure aligns with your system’s air supply and regulator settings to avoid under or over-pressurization.
- Mounting options: Review available mounting styles (side, rear, pivot) to ensure compatibility with fixtures, guides, and end-effectors.
- Environmental suitability: For washdown or corrosive environments, verify seals, coatings, and surface finishes meet cleanliness and durability requirements.
- Maintenance and compatibility: Consider availability of spare seals, rods, end caps, and ease of disassembly for maintenance in your facility.
- Integration with control systems: Ensure compatibility with existing PLCs and control logic, including switchless or switch-equipped variants if needed.
When selecting a stainless steel pneumatic cylinder, balance mechanical performance with environmental demands.
