Specifications:
The document provides detailed specifications for double-acting compact cylinders, model MCJQ-3*. The cylinders are available in various tube internal diameters (I.D.) ranging from ø12 to ø100 mm. The operating pressure range is 0.07~1 MPa for smaller diameters and 0.05~1 MPa for larger ones, with a proof pressure of 1.5 MPa. The ambient temperature range is -5°C to +60°C, and the available speed range is 50~500 mm/sec. The medium used is air, and the port sizes vary from M5×0.8 to Rc3/8 depending on the tube I.D.

Standard and Long Strokes:
The document includes tables listing standard and long stroke lengths for different tube I.D.s. For example, ø12 and ø16 have standard strokes of 5 to 30 mm and long strokes up to 100 mm, while ø25 has long strokes up to 300 mm.

Features:
The cylinders are double-acting and can be ordered with or without magnets. They are constructed from materials such as aluminum alloy for the body and covers, stainless steel for the piston rod, and NBR for various packings and gaskets.

Order Example:
The order code includes the model, tube I.D., stroke lengths, port thread type, and additional features like magnets or rear flanges. The total stroke must be greater than the first stroke.

Inside Structure & Parts List:
The document provides a detailed parts list for the compact cylinders, including materials and quantities for each component. Repair kits are available for each tube I.D.

Dimensions:
Detailed dimensions are provided for cylinders with tube I.D.s from ø12 to ø100, including measurements for various components and configurations for both standard and long strokes.

Recommendations:
Users are advised to contact the manufacturer if the required stroke is outside the specified range. The document also references additional pages for sensor switch specifications and special order examples.
