SMC AM32A AM series standard cylinder Single-Acting

Core parameters

Item Technical specifications

Action type Single acting (spring return)

Cylinder diameter 32mm (Φ32)

Stroke range 10-300mm (standard product)

Working pressure 0.15-0.7MPa (spring return force limit)

Reset spring force 58N (standard spring)

Effective thrust 643N@0.5MPa (spring force must be deducted)

Interface size Rc1/8

Buffer type Rubber buffer (extended end only)

Basic model: AM32A-100 (100mm stroke)

Key suffixes:

-D-M9B: with magnetic switch

-CA: foot mounted type

-S: stainless steel version (AM32AS)

IV. Selection points

Load verification:

When installed vertically, it must meet: load weight < (Effective thrust/1.5)

Example: Maximum vertical load at 0.5MPa ≈ 390N (about 40kg)

Stroke limit:

Strokes exceeding 200mm require special customization (spring force attenuation)

Pressure limit:

Maximum 0.7MPa (to prevent excessive compression of the spring)

V. Typical applications

Safety mechanism:

Emergency brake device (automatic reset when power is off)

Safety door push (AM32A-150-D-M9B)

Light equipment:

Packaging machine baffle (AM32A-80)

Classification mechanism push rod

Energy-saving occasions:

Simple actions that only require unidirectional work

VI. Maintenance precautions

Spring life:

Standard product: 500,000 cycles (recommended replacement every 2 years)

Detection method: Measure reset time (new parts ±10%)

Lubrication requirements:

Add ISO VG32 lubricant every 6 months

Lubricants containing silicone oil are strictly prohibited

Fault code:

F01: Delayed reset → Check spring/lubrication

F02: Stop midway → Check if the load is overloaded

VII. Supporting system solution

Component type Recommended model Remarks

Solenoid valve SY3120-5LZ Two-position three-way single control type

Speed control valve AS1201F One-way reciprocating speed control

Mounting bracket CA32 Aluminum alloy foot

Special instructions:

It is recommended to install a mechanical locating pin (PXS32) in a vibrating environment

Food-grade applications require optional FKM seals (AMK32-FKM)
