Description

Linch pin, also called a locking pin, in zinc-plated steel is intended for use in environments where quick and secure locking is required. The product complies with DIN 11023 and is used to secure bolts, pins, and shafts against axial displacement. The spring-loaded hoop design provides a self-locking function that enables quick installation and removal without tools. It is suitable for applications where reliable locking and easy handling are essential.

FIELD OF APPLICATION

The product is used in agricultural machinery, construction equipment, trailers, implements, and mechanical constructions. It is intended for applications where frequent disassembly and reassembly are required, such as when coupling implements or adjustable components. The linch pin provides secure locking while allowing quick access for service and adjustment.

FREQUENTLY ASKED QUESTIONS (FAQ)

What characterizes a linch pin (DIN 11023) and how does the locking mechanism work?

A linch pin (also called a locking pin or quick-release pin) is a quick-locking fastener designed to secure pins, shafts, and bolts:

  • Self-locking spring hoop: The pin features a rounded, resilient steel hoop that folds over the end of the shaft during installation. The tension of the hoop keeps the pin firmly in place and prevents it from shaking loose or sliding out due to vibrations.

  • Standardized according to DIN 11023: Meets strict dimension and strength requirements for fit and reliability in agricultural and machinery applications.

  • Tool-free handling: Enables lightning-fast installation and removal by hand, making it ideal for equipment and implements that need to be coupled frequently.

Why is zinc-plated steel the right material choice for linch pins?

  • High mechanical strength: Made of hardened steel to withstand high shear forces and impacts without bending or breaking under load.

  • Corrosion protection for outdoor environments: The zinc plating protects the steel against rust, moisture, dirt, and weather impact during daily use in agriculture and construction.

  • Spring steel with long service life: The hoop retains its tension and locking force even after thousands of openings and closings.

Where are linch pins best used and what should be considered during use?

  1. Common application areas: Used extensively on tractors, agricultural implements, trailers, three-point hitches, construction machinery, and industrial carts where pins and bolts must be secured quickly.

  2. Choose the right dimension: Ensure that the pin diameter exactly matches the hole in the bolt or shaft. A pin that is too small creates play and wear, while a pin that is too large will not fit through.

  3. Check the position of the hoop: During installation, the spring hoop must always be folded completely over the side of the pin so that it rests firmly and locks the pin securely.
