Square Pancake II Catalog

Product catalog summary
Overview: The Square Pancake® II Air Cylinders catalog provides comprehensive details on the Square Pancake® II series, known for their compact design and reliable performance. It includes specifications, ordering information, and options for various models and configurations suitable for different industrial applications.
Specifications: The cylinders are available in configurations such as double acting, single rod, double rod, and single acting with spring retraction or extension. Bore sizes range from 3/4" to 4", with strokes up to 4". They feature a high-strength composite body, stainless steel tie bolts, and chrome-plated stainless steel piston rods, designed for a maximum pressure of 200 psi and operating within a temperature range of -25°F to +221°F.
Key Features: The cylinders have a self-lubricating composite body, high impact resistance, and a low coefficient of friction. Duralon® rod bearings provide high load-bearing capacity and minimize friction, enhancing the cycle life. Internally lubricated Buna-N O'Ring seals and optional U-Cup seals improve media compatibility.
Ordering Information: To order, specify the series, model, action, bore, optional mounting, stroke, and additional options in alphabetical order. Examples are provided to guide the ordering process.
Options and Accessories: Options include bumpers, magnets for position sensing, low friction seals, and different rod end configurations. Magnetic position sensing is available with a minimum stroke of 3/8". Additional mounting options include pivot mounts with pins either in-line or 90° from the port.
Dimensions and Weights: Detailed dimensions are provided for each model, with standard strokes ranging from 1/8" to 4". Approximate weights are listed for each bore size and model configuration.
Performance and Materials: The catalog highlights the superior performance of Duralon® rod bearings, resistant to corrosion, moisture, and high temperatures. The cylinders are designed to prevent slip-stick issues common in metal cylinders, ensuring smooth operation even after extended static periods.
Additional Specifications: The document also covers non-rotating, twin rod series SND, with technical data on thread sizes, materials, pressure ratings, temperature ratings, and mounting options. Stroke tolerance is ±1/64".
Thread Sizes: Fine Threads (TFM) range from #10-32 UNF to 3/4-16 UNF, and Coarse Threads (TCM) range from #10-24 UNC to 3/4-10 UNC.
Mounting Options: PM Pivot Mount with pin 90° from port and SM Pivot Mount with pin in line with port, both with bronze pivot bushing.
Pricing: Base prices are listed by bore size with additional costs for mounting options and specific features.
Accessories: Includes clevis brackets and rod eyes with detailed dimensions and kit numbers for different bore sizes.
