Product Description:
What is a quick release pin?
Quick release pins, also known as ball lock pins, locking pins or
safety pins, have a wide range of applications. They are used for
securing, locking, connecting, adjusting and facilitating quick
position changes.
When paired with a receiver plate, these pins provide a reliable
and secure locking feature. The design ensures ease of use and
facilitates quick changeover and replacement of parts as needed.
Quick release pins are highly resistant to shear, corrosion and
wear. This makes them ideal for applications that require frequent,
quick, manual assembly and disassembly of products.
Quick release pins are fastening connectors for quick locking and
removal of workpieces, and can be used to quickly connect and hook
up components. Pressing the button on the handle can make the steel
ball on the head of the pin body retract and push the quick release
pin through the hole of the workpiece; when the button is released,
the steel ball pops out and the quick release pin can not be pulled
out from the hole.
The pin body diameter and clamping length are processed with high
precision, which is suitable for all kinds of high-precision
positioning and insertion. Can be customised according to
customer's requirements.
Quick Release Pin Head and Handle Styles
Quick release pins usually have a pin and a handle and come in a
variety of handle styles. As such, they can also be categorised by
head/handle type:
T-Handle Quick Release Pins, Ring Handle Quick Release Pins,
L-Handle Quick Release Pins, Push Button Handle Quick Release Pins,
Double Acting Quick Release Pins, Lifting Pins
T-Handle A wide range of handles featuring a T-shaped handle for a
firm grip and simple operation. Attached parts are easily released
by pulling and holding the handle.
L-Handle Quick-Release Pins A compromise between the ring handle
and T-Handle variants. The release mechanism has an L-shaped handle
on only one side of the pin. These are suitable for applications
where a firm grip is required but there are space constraints.
Applications
Carbon steel release pins in grades 4.8, 8.8, and 12.9 are crucial
components used in heavy machinery and mining equipment. These
pins, available in sizes ranging from M3 to M18, provide the
necessary strength and durability to perform in the most demanding
environments. The high tensile strength of these carbon steel
grades ensures that the release pins can withstand the heavy loads
and extreme conditions typical of the mining and construction
industries.
In the mining industry, release pins are used in equipment such as
excavators, draglines, and haul trucks. These heavy machines are
exposed to intense stress and rough conditions, and the release
pins ensure that critical components can be quickly and safely
assembled or disassembled for maintenance and repairs. The high
strength of carbon steel grades 4.8, 8.8, and 12.9 guarantees that
the pins will not bend or break under the intense loads, reducing
the need for frequent replacements and downtime.
Similarly, in heavy machinery, release pins are used in a wide
variety of applications, from securing parts of large cranes to
fastening components in construction equipment. These release pins
are designed for both easy installation and removal, enabling
operators to perform repairs or maintenance with minimal effort.
The corrosion resistance of carbon steel ensures that the pins
maintain their integrity in exposed, harsh outdoor environments,
making them reliable components in heavy-duty machinery.
The versatility of these release pins also means they can be used
in a wide range of machinery sizes, from smaller equipment to
large-scale machinery. Whether used in the mining industry or for
other heavy equipment, these carbon steel release pins are
indispensable for ensuring operational efficiency and safety.
