Description
Basic Parameters
The CY-12A is a compact universal ball bearing designed for lightweight dynamic applications, featuring a 12mm outer diameter (OD) with a precision-machined steel housing and a nylon-coated main ball for reduced friction and noise. With a nominal bore compatible with M8 threaded mounts (common in modular conveyor systems and smart car casters), it offers bidirectional mobility with a rated static load capacity of up to 20 kg, suitable for low-speed operations in machinery, furniture, or robotics. The bearing incorporates a carbon steel raceway and corrosion-resistant zinc plating (standard variant), while optional 304 stainless steel versions provide enhanced durability in humid environments. Its 6mm ball diameter and lightweight nylon retainer ensure smooth rotation, compliant with ISO 15 boundary dimensions for interchangeability. Ideal for applications requiring space-efficient omnidirectional movement, the CY-12A measures 14mm in overall height (including flange) and adheres to ABEC-1 precision standards, balancing cost-effectiveness with reliable performance in DIY projects and light industrial setups.
Product Application
Ideal for space-constrained environments like 3C electronics assembly lines and warehouse sorting systems, the CY-12A’s 12mm outer diameter (with 14mm overall height) and M8 threaded flange enable seamless integration into aluminum extrusion frameworks or modular conveyor setups. Its nylon-coated main ball reduces friction, achieving noise levels below 65dB—12% quieter than traditional metal bearings—while ensuring scratch-free transport of delicate components. In a leading e-commerce warehouse, a sorting module equipped with 500 CY-12A bearings processed over 2,000 parcels under 5kg per hour, demonstrating reliability in high-frequency, low-load operations.
For intelligent furniture requiring hidden mobility—such as electric lift-top coffee tables, medical carts, or premium sliding drawers—the CY-12A’s composite structure (e.g., PL/CS material, weighing 0.021kg) offers optimal load-bearing and smooth motion. A Chinese furniture manufacturer validated its 3kg static load capacity (PL/CS version), enabling a 600mm×400mm panel to glide at any angle with radial runout ≤0.5mm. This design extends product lifespan to over 100,000 operation cycles—twice the national standard—enhancing user experience in high-end home and healthcare applications.
In AGV carts and STEM robotics platforms, the CY-12A’s 360° bidirectional rotation (powered by 6mm steel balls) eliminates steering jams, critical for autonomous navigation. A Shenzhen tech startup outfitted a 15kg educational robot with four CY-12A units (CS/CS material, 7kg load per set), achieving stable 0.3m/s movement on 30° slopes. Its ISO 15-compliant dimensions allow 2-minute quick replacements, reducing maintenance costs by 40%—a key advantage for modular robotic systems requiring rapid repairs.
The corrosion-resistant SS/SS stainless steel variant (5kg load) meets harsh requirements in food processing and laboratory equipment. Installed in a bakery’s dough mixer outlet, it withstood 720 hours of salt spray testing without rust, paired with a detachable nylon retainer for 5-minute quick cleaning, compliant with FDA hygiene standards. In cold-chain logistics (-20℃ environments), the zinc-plated carbon steel version (CS/CS) operates reliably down to -30℃, ensuring smooth mobility for warehouse trolleys in freezing conditions.
With a “gradient parameter” design—four material combinations supporting 3–20kg loads—the CY-12A appeals to DIY enthusiasts and innovators. A university team integrated the PL/SS variant (4kg load) into a smart flowerpot base, using Arduino to control five bearings for sunlight-tracking rotation, with a total cost of $1.70 per set. This blend of miniaturization and cost-effectiveness positions the CY-12A as more than an industrial component; it serves as a versatile “universal joint” bridging traditional machinery and smart devices, driving innovation across consumer and professional sectors.
