Shearing machines, presses, molding machines, tool bases, ress brakes, and shock loading applications all use spring loaded units. Spring loaded ball units reduce damage caused by shock loads. They also allow for temperature-related dimension changes and self-adjust to evenly distribute loads.
Features include a solid steel body machined from a single piece of steel using a CNC machine, a zinc-plated surface treatment, a bearing steel ball with a high load capacity, an incorated spring with shock loading, and a top flange fixing.

This is a combined device whose core function is to provide a multi-directional rolling support point with elasticity and automatic reset capability.
Working Principle:
Load Bearing & Rolling: When an object (e.g., workpiece, equipment, plate) moves across this device, its weight presses down on the ball of the ball transfer unit. The ball transfer can roll in any horizontal direction with low friction, thereby easily guiding and moving heavy objects.
Cushioning & Compression: When the load is excessive or a downward impact occurs, the pressure overcomes the preload of the internal spring, causing the entire ball transfer unit (including the housing and the ball) to compress the spring downward.
Automatic Reset & Height Compensation: When the load decreases or the impact disappears, the spring pushes upward, returning the ball transfer unit to its original height. This design compensates for uneven equipment or track surfaces and absorbs vibration and shock.
Ball Transfer Head: The core moving component. Typically consists of a precision metal (e.g., carbon steel, stainless steel) or nylon ball, and a matching socket (bearing housing). The socket usually contains multiple small ball bearings ensuring the ball rotates smoothly in multiple directions.
Spring: The core functional component. Installed beneath the ball transfer head, it provides the upward thrust and cushioning capability. The spring force is designed according to load requirements.
Flange Mounting Base: The structural base and installation interface. It is a disc-shaped or cylindrical structure with a circle of mounting holes. It can be easily and securely fixed to equipment platforms, frames, or support plates in conveyor lines using bolts or screws.
Housing/Sleeve: Usually a cylindrical structure that encloses the spring and part of the ball transfer socket. It serves to protect the spring, prevent dust and debris from entering, and guide the spring's vertical movement.
Cushioning & Shock Absorption: The spring effectively absorbs impacts and vibrations generated during handling, protecting the conveyed precision equipment and products.
Self-Adapting Height: Can automatically compensate for uneven support surfaces, ensuring all support points share the load evenly.
Surface Protection: Reduces rigid impacts on both the equipment and the ball transfer unit itself, extending service life. For conveyor surfaces made of soft materials (e.g., wood, certain plastics), the spring pressure can prevent indentations.
Flexibility & Low Friction: Retains the inherent multi-directional rolling capability of ball transfers, making positioning and turning heavy objects very easy.
Easy Installation: The flange design allows for very quick and secure installation, simply requiring bolting down.
Adjustable Preload (Some Models): Some high-end models may offer adjustable spring preload to accommodate different load requirements.
This device is widely used in material handling and processing systems requiring flexibility, cushioning, and precise positioning:
Assembly Line Conveyor Systems: Acts as a cushioning and turning station, especially at junctions where workpieces need to transition smoothly from one line to another.
Die/Mold Changing & Positioning: Used in large stamping presses, injection molding machines, etc., to support and facilitate the movement of heavy molds.
Precision Assembly Platforms: Serves as support points on precision assembly tables where manual fine-tuning of heavy component positions is required.
Heavy Equipment Translation: Used for moving machine tools, large cabinets, etc.; the spring loading can absorb vibrations caused by uneven floors.
Lifters & Lifting Platforms: Serves as guiding and cushioning support points for the platform.
Specialized Tooling & Fixtures: In testing or processing stations where workpiece "floatation" is needed.
Load Capacity: This is the most critical selection parameter. The maximum static and dynamic load that each ball unit needs to bear must be calculated, and a product with corresponding specifications must be selected. Load capacity is primarily determined by the spring stiffness.
Stroke: The maximum compressible distance of the spring. It is necessary to ensure this stroke is sufficient to handle expected height variations and impacts.
Ball Material & Size:
Material: Stainless steel balls are corrosion-resistant, suitable for food, pharmaceutical, or clean environments; carbon steel balls are economical and have high load capacity; nylon balls will not scratch product surfaces.
Size: Larger ball diameters generally provide smoother rolling and higher load capacity.
Installation Dimensions: Verify that the flange's hole diameter, hole spacing (PCD), and overall dimensions are suitable for the available space on the equipment.
Operating Environment: Consider temperature, humidity, presence of corrosive chemicals, etc., to select the appropriate material (e.g., stainless steel) and lubrication type.
The Spring-Loaded Flange-Mounted Ball Transfer Unit is a high-performance industrial component that integrates rolling, cushioning, and convenient installation functions. Through simple mechanical principles, it solves problems related to friction, impact compensation, and precise positioning in heavy load handling. It is an indispensable and "smart" small component in automation equipment and material handling systems.
