lynch pin, or linchpin, is a small but essential hardware component used to securely fasten wheels, gears, or other rotating parts to shafts or axles, preventing them from sliding off. It’s often a simple metal pin that passes through a hole at the end of a shaft and has a spring-loaded loop or collar that keeps it in place.

Here are some common applications of a lynch pin:
Used in tractors and other farm machinery to secure implements like plows, cultivators, and trailers to the main equipment. It makes it easy to attach and detach different tools and accessories.
Commonly used to secure trailer hitches and attachments. In some cases, they’re also used to hold spare tires or other parts in place.
Found in heavy-duty equipment like excavators, bulldozers, and cranes, lynch pins prevent attachments from coming loose while in operation.
Used in conveyor systems and other machinery where components need to be securely attached yet easily removable for maintenance or replacement.
On bike trailers, for instance, a lynch pin is often used to connect the trailer to the bike quickly.
Lynch pins are ideal for applications where quick assembly and disassembly are necessary without tools. In your factory, lynch pins might also be used for securing parts of assembly lines or holding equipment in place that may need routine adjustments.
Lynch Pin Sizes: Choosing the Right Fit
Lynch pins come in multiple sizes, each suited to specific applications. Selecting the right size is crucial for safety and efficiency. Here’s a guide to common sizes:
Lynch pins range in diameter from 3 mm to 16 mm or 1/8 inch to 5/8 inch. The pin diameter should match the hole size on the shaft to prevent excessive movement and ensure stability.
The usable length of a lynch pin varies based on the equipment. Standard lengths range from 20 mm to 100 mm or 3/4 inch to 4 inches. For larger industrial equipment, a longer length provides additional stability.
This thickness typically ranges from 1.5 mm to 3 mm or 1/16 inch to 1/8 inch. Heavy-duty applications require thicker clips for added durability.
The overall length, including the handle or ring, can range from 30 mm to 120 mm or more. This length can affect ease of handling and compatibility in tight spaces.
