Overview

This document provides a comprehensive technical guide for the MCMA series miniature pneumatic cylinders, covering specifications, features, components, accessories, and ordering information. These cylinders are designed for durability, corrosion resistance, and maintenance-free operation due to their self-lubricating design.

1. Product Features

• High-quality miniature cylinders with long service life.
• Self-lubricating piston rod enabled by special housing and bushing, eliminating the need for external lubrication.
• Hard anodized stainless steel cylinder tubes offer high corrosion resistance and low internal friction.
• Available mounting accessories support both rigid and flexible installation methods.
• Operation types include single acting and double acting, with options for single or double rods (except MCMA-11).
• Standard stroke lengths are available, with customization possible upon consultation.

2. Cylinder Specifications

• Tube Inner Diameters (I.D.): 16 mm, 20 mm, 25 mm, 32 mm, 40 mm.
• Stroke Lengths: Standard strokes range from 15 mm to 500 mm depending on tube size and acting type.
• Operating Medium: Air.
• Maximum Operating Pressure: Up to 1.5 MPa (document shows 0.7 MPa in one section, 1.5 MPa in another; max pressure should be verified per model).
• Minimum Operating Pressure: Double acting: approx. 0.05–0.06 MPa; Single acting: approx. 0.15 MPa.
• Speed Range: 50 to 500 mm/sec.
• Ambient Temperature: -5°C to +60°C; freezing conditions must be avoided.
• Lubrication: Not required due to self-lubricating design.
• Port Sizes: M5×0.8 for φ16; Rc1/8 or other thread types (Rc, G, NPT) for φ20 to φ40 depending on model.
• Proof Pressure: Typically 1 MPa or higher depending on model.
• Sensor Switch Compatibility: Magnetic sensors standard; compatible with RCA, RCM, RCS sensor bands matched to tube sizes.

3. Model and Ordering Information

Models are designated by tube I.D., stroke length, rod style (single or double), cushion options, pivot types, and port thread types. Example format: MCMA-11-32-100-A-N-□, where each segment specifies key features. Ordering codes allow customization for specific application needs.

4. Mounting Accessories

A wide range of mounting accessories is available to support various installation requirements, including:

• Mounting brackets: LB, FA, FB, SDB, CA, CB, TA, TB.
• Connector pins: Y, I, floating pins (MFC, MFCS), split pins.
• Female rod ends, sensor switches, fittings, and speed controllers.

Each accessory is coded and dimensioned for compatibility with specific tube I.D.s and cylinder types.

5. Internal Structure and Materials

The cylinder assembly includes components such as rod cover, head cover, tube, piston rod, piston (various types), piston gasket and packing, magnet ring, wear ring, washers, piston bolt, cushion gaskets, rod bush, rod packing, snap rings, tie nuts, port plugs, needle valves, and steel balls.

Materials used span plastic, aluminum alloy, stainless steel, carbon steel, spring steel, bearing alloys, magnet materials, and Teflon with graphite for sealing and wear parts.

6. Repair Kits and Maintenance

Repair kits are available tailored to tube I.D. and cylinder configuration (standard and non-pivot types). Kits include seals, gaskets, and wear parts necessary to maintain cylinder performance and extend service life.

7. Dimensions and Technical Data

Extensive dimensional tables provide critical data for installation and integration, including:

• Mounting hole sizes and positions.
• Thread specifications for ports and mounting screws.
• Stroke length options and corresponding cylinder dimensions.
• End cover types (standard and pivot).
• Sensor switch installation dimensions and compatibility.

Dimensions are detailed separately for double acting and single acting cylinders, ensuring precise selection.

8. Sensor Switch Installation

Sensor switch options include RCA, RCM, and RCS models with corresponding sensor bands (BA**, BM**, BGS**). Compatibility depends on tube I.D., and installation codes are provided to ensure proper fit and function.

9. Critical Information and Recommendations

• Stroke lengths outside standard specifications require prior consultation.
• Lubrication is not necessary due to the self-lubricating design.
• Operating temperature must remain within -5°C to +60°C to prevent freezing and damage.
• Sensor switch bands must match the tube I.D. for reliable operation; BM** bands are exclusive to RCM switches.
• Port thread types vary by tube size and must be selected accordingly (M5×0.8, Rc, G, or NPT).
• Ensure mounting accessories are compatible with the selected tube I.D. and stroke length.

Summary

The MCMA series miniature pneumatic cylinders offer robust, corrosion-resistant, and maintenance-free solutions for pneumatic automation. Their self-lubricating design reduces upkeep, while a broad selection of mounting accessories, sensor switches, and repair kits supports diverse application needs. Detailed specifications and dimensional data facilitate accurate selection, ordering, and integration into pneumatic systems.
