The spherical universal ball is an industrial transmission component capable of achieving multi-directional flexible rotation.£¬ also called ball transfer unit. It is widely used in material conveying, mechanical equipment movement, and automated production lines, effectively reducing frictional resistance and achieving smooth and effortless omnidirectional movement.
Core structure and working principle
Basic composition
Consisting of a housing, balls (spheres), and a fixed seat, some high-load products also contain multiple sets of small balls or rollers inside, achieving multi-directional movement through rolling friction.
Motion mechanism
When external force is applied, the ball rolls in any direction within the housing, allowing the load-bearing object to slide freely in a horizontal plane through 360 degrees. This converts "sliding friction" into "rolling friction", significantly reducing the starting resistance.
Material and type
The shell is commonly made of carbon steel galvanized, stainless steel, or reinforced nylon
Ball bearings are mostly made of bearing steel, carbon steel, or plastic steel to ensure high strength and wear resistance
Main classification and application scenarios
By carrying capacity: light-duty (<50kg), medium-duty (50¨C250kg), heavy-duty (>250kg)
The heavy-duty model utilizes high-strength materials and a built-in lubrication system, making it suitable for equipment that requires frequent steering and carries heavy loads.
By installation method: flange type, press-in type, screw type, adhesive type, etc., facilitating integration into different mechanical structures
Typical application areas:
Conveyor platforms for assembly lines in industries such as electronics, hardware, and food
AGV vehicle, logistics sorting system, and packaging machinery auxiliary equipment
Flexible transfer of objects with flat bott
om
surfaces, such as workbenches, material boxes, and palletsAdvantages and Features
Achieve passive, low-friction, omnidirectional sliding, saving manpower and energy consumption
Modular design, with adjustable distribution density and load-bearing capacity
Compact structure, suitable for mechanical equipment integration with limited space
Spherical universal ball bearings play an irreplaceable role in industrial automation, especially in scenarios requiring frequent direction changes and precise positioning.
