Spring Loaded Rolling Pin Catalog
Rolling pogo pin, also known as spring loaded rolling pins, rolling ball spring contacts, or through hole spring loaded rolling pins, are primarily used to establish reliable electrical or signal connections between components. They ensure consistent conductivity and stable contact performance in various electronic applications.

What is a rolling pogo pin
Rolling pogo pin is a type of spring loaded electrical contact designed for reliable power or signal transmission. It is also known as a rolling ball contact pin or rolling ball spring loaded pin. Their core function is to conduct electricity or signal transmission. The pin mainly consists of four core components: a rolling ball, solid pin, spring, and outer body. When the pogo pin is in operation, the inclined plane generates lateral force that pushes the rolling ball against the inner wall of the body, maintaining stable contact pressure. This allows the electrical current to flow primarily through the gold plated rolling ball and body, achieving very low and stable contact resistance even during frequent insertion, movement, or repeated use.
How to install rolling pogo pin
Installing a rolling pogo pin requires special attention to the rolling function, which is the key advantage over traditional sliding pogo pins. First, prepare the mounting hole or housing according to the specified diameter and depth, ensuring smooth inner walls so the rolling ball can rotate freely. Insert the rolling pogo pin with the rolling ball facing the mating surface. Proper alignment is critical: the pin must be installed perpendicular to the contact surface so the rolling ball can roll instead of slide during movement. Fix the pogo pin using press fit, soldering, or a dedicated holder, depending on the design. During installation, apply controlled compression to confirm that the spring responds smoothly and the ball rotates without sticking. After mounting, test the rolling action by simulating movement or rotation of the mating part. Verify stable contact force, low contact resistance, and continuous electrical connection while the rolling ball is in motion.
rolling pogopin material & parts
Rolling pogo pin is a specialized type of pogo pin connector designed for stable electrical conduction with minimal wear. It belongs to the vertical contact and side contact categories and is built around a bevel structure with an internal spring mechanism. The rolling pogo pin consists of four core parts: the rolling ball, solid pin, spring, and body.
The body and solid pin are typically made from lead free copper alloy with gold plating, ensuring excellent conductivity and corrosion resistance. The spring is usually made of lead free stainless steel, providing stable elastic force and long fatigue life. The most critical component is the gold plated rolling ball, which can rotate freely through 360 degrees.
This rolling contact design allows the ball to roll instead of slide during movement, greatly reducing friction, surface wear, and debris generation. As a result, rolling pogo pins achieve extremely low contact resistance, stable signal transmission, and superior durability in dynamic or high cycle applications.
rolling pogopin Internal structures
The internal structure of a rolling ball spring loaded contact is based on a ball and bevel design, specifically developed to achieve stable rolling contact and long term reliability. Inside the contact pin, the inclined bevel surface works together with the internal spring to generate controlled lateral force during compression. This force continuously pushes the rolling ball against the inner wall of the needle tube, allowing the ball to roll smoothly instead of sliding. As a result, friction and surface wear are significantly reduced. The rolling ball maintains consistent contact pressure and a stable electrical path through the gold plated ball and body. This structure ensures low and stable contact resistance, even under vibration, movement, or repeated mating cycles, making rolling ball spring loaded contacts ideal for dynamic and high cycle electrical applications.
How Rolling Pogo Pins Work
Rolling pogo pins work by carefully balancing contact force and contact resistance, which are essential for a stable and reliable electrical connection. These two factors are closely related: as contact force increases, contact resistance is effectively reduced. Inside the rolling pogo pin, the bevel structure and internal spring generate lateral force during compression. This lateral force is converted into a consistent contact force that presses the gold plated rolling ball firmly against the inner wall of the needle tube. Because the ball maintains stable pressure while rolling instead of sliding, contact resistance remains extremely low and stable. This mechanism ensures reliable signal or power transmission even during movement, vibration, or repeated operating cycles.
Dip Pogo Pin Contact Resistance
This chart illustrates that during the full compression and release stroke of the dip pogo pin, the spring force increases smoothly while the contact resistance remains extremely low and stable. This demonstrates a well-engineered internal structure, precise machining tolerances, and high-quality vacuum blind-hole plating that together ensure reliable electrical connectivity and long-term performance stability.
