MCJI Compact Cylinder Technical Summary

1. Product Overview

The MCJI series compact cylinders conform to ISO-21287 standards and offer a wide range of bore sizes and stroke lengths. They are designed to be ultra-compact, lightweight, and space-saving. The cylinders feature sensor slots on the RCI sides for flush mounting of proximity sensors and include magnetic pistons as standard.

2. Specifications

• Bore Sizes: φ12, 16, 20, 25, 32, 40, 50, 63, 80, 100 mm
• Stroke Lengths: Standard strokes range from 5 mm up to 500 mm depending on bore size, with specific maximum strokes for each bore.
• Operating Pressure Range: 0.05 to 1.5 MPa (air)
• Proof Pressure: 1.5 MPa
• Operating Temperature: -5°C to +60°C (no freezing)
• Speed Range: 50 to 500 mm/sec
• Port Size: G1/8 for larger bores (32 mm and above), M5 to M16 thread sizes for smaller bores
• Lubrication: Without lubrication

3. Construction and Materials

• Tube and Covers: Aluminum alloy
• Piston Rod: Stainless steel for φ20 and φ25; medium carbon steel for φ32 to φ100
• Seals and Packing: NBR (Nitrile Butadiene Rubber)
• Magnet Ring: Magnetic material integrated in piston
• Wear Rings and Bushings: Bearing alloy and Teflon for durability

4. Dimensions and Mounting

The document provides detailed dimensional tables for bore sizes φ12 to φ100, including parameters such as stroke length, mounting hole sizes, thread sizes, and accessory compatibility. Mounting accessories include LB, FAC, FBC, MP, CA, CB+PIN, floating joints (MFC, MFCS), female rod ends (PHS), fittings (PC), speed controllers (JSC), and sensor switches (RCI).

5. Sensor Switch Installation

Sensor switches (RCI) can be installed in dedicated slots on the cylinder body. The switches are available in reed or solid-state types, with options for lead wire or connector types. Installation requires set screws and follows specific order codes based on tube I.D. and stroke length.

6. Accessories and Repair Kits

• Mounting accessories are categorized by type and bore size compatibility.
• Repair kits and component parts are available for all bore sizes, with detailed part numbers and weights provided.
• Common accessories include connection blocks, flanges, bolts, and pins.

7. Ordering Information

Order examples are provided for standard and special specifications. The model code includes cylinder type, tube I.D., stroke length, and sensor switch options. Special specifications require consultation.

8. Important Notes and Limitations

• Stroke length tolerance is ±0 to +1.0 mm and does not include bumper deformation.
• Maximum overall stroke length must not be exceeded when combining cylinders with multi-position kits.
• Consult manufacturer for stroke lengths outside standard specifications.

Summary

The MCJI compact cylinder series offers a versatile, standardized pneumatic cylinder solution with a broad range of sizes and strokes, suitable for applications requiring compact design and sensor integration. Detailed dimensional data and accessory options support flexible installation and maintenance.
