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

Product Specifications

Technical details and manufacturing context for Stroke Limiter

Definition
The Stroke Limiter is a critical safety and precision component within the Stroke Length Adjustment Mechanism that physically prevents a piston, rod, or other moving element from exceeding a predetermined maximum extension or retraction point. It ensures operational safety by preventing over-travel and maintains system integrity by protecting against mechanical damage from excessive force or misalignment.
Working Principle
The limiter functions by providing a physical stop or obstruction at a fixed point along the path of the moving component. When the component reaches this point during its stroke, contact with the limiter halts further motion. This can be achieved through adjustable hard stops, collars, pins, or integrated features within the mechanism's housing or guide rails.
Common Materials
Hardened Steel, Alloy Steel
Technical Parameters
  • The maximum allowable stroke length that the limiter permits. (mm) Per Request
Components / BOM
  • Stop Block / Collar
    The primary physical obstruction that makes contact with the moving part to halt its motion.
    Material: Hardened Steel
  • Mounting Bracket / Base
    Secures the limiter to the main frame or housing of the adjustment mechanism.
    Material: Steel
  • Locking Mechanism (e.g., set screw, clamp)
    Allows for adjustment and secure locking of the limiter's position along a rail or threaded rod.
    Material: Steel
Engineering Reasoning
0.5-150 mm stroke restriction
Plastic deformation at 250 MPa yield stress or 0.2 mm permanent deformation
Design Rationale: Stress concentration at fillet radius exceeding material yield strength (σ_max > σ_yield) due to Hertzian contact stress from impact loading
Risk Mitigation (FMEA)
Trigger Corrosion pitting at stress concentration points (fillet radius < 0.5 mm)
Mode: Fatigue crack initiation and propagation at corrosion pits
Strategy: 316L stainless steel with 0.8 mm minimum fillet radius and 25 μm electropolished surface finish
Trigger Impact loading exceeding 500 N at 2 m/s velocity
Mode: Plastic deformation at contact interface causing permanent set
Strategy: Hardened tool steel (60 HRC) impact surface with 15° chamfer and energy-absorbing polyurethane damper

Frequently Asked Questions

What materials are used in your stroke limiters?

Our stroke limiters are manufactured from high-strength materials including hardened steel and alloy steel for durability and wear resistance in industrial environments.

How does a stroke limiter work in machinery?

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.

What components are included in a typical stroke limiter BOM?

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.
