# Industrial Specification: Stroke Limiter

## 1. Technical Definition
A mechanical component that restricts the maximum travel distance of a moving part within a stroke length adjustment mechanism.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-150 mm stroke restriction**. Failure boundary: **Plastic deformation at 250 MPa yield stress or 0.2 mm permanent deformation**, Mechanism: **Stress concentration at fillet radius exceeding material yield strength (σ_max &gt; σ_yield) due to Hertzian contact stress from impact loading**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Corrosion pitting at stress concentration points (fillet radius &lt; 0.5 mm) | 8 | Fatigue crack initiation and propagation at corrosion pits | 316L stainless steel with 0.8 mm minimum fillet radius and 25 μm electropolished surface finish |
| Impact loading exceeding 500 N at 2 m/s velocity | 8 | Plastic deformation at contact interface causing permanent set | Hardened tool steel (60 HRC) impact surface with 15° chamfer and energy-absorbing polyurethane damper |

## 3. Key Technical Parameters

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are used in your stroke limiters?
**A**: Our stroke limiters are manufactured from high-strength materials including hardened steel and alloy steel for durability and wear resistance in industrial environments.

### Q: How does a stroke limiter work in machinery?
**A**: A stroke limiter mechanically restricts the maximum travel distance of moving parts within stroke length adjustment systems, typically using stop blocks, collars, or locking mechanisms to prevent over-travel.

### Q: What components are included in a typical stroke limiter BOM?
**A**: A complete stroke limiter typically includes a locking mechanism (such as set screws or clamps), mounting bracket/base for secure installation, and stop block/collar components that physically limit movement.
