Description

Basic Parameters

The CY-12B universal ball bearing is a compact, lightweight solution designed for low-to-medium load applications requiring 360° rotational flexibility. With a nominal inside diameter (d) of 12 mm and outside diameter (D) of 28 mm, it features an axial width (B) of 8 mm, yielding a balanced B/D ratio of 0.29, optimized for stability in confined spaces. The bearing incorporates 8 precision-grade chrome steel balls (nominal diameter db = 3.175 mm), retained in a phenolic cage to minimize friction and ensure smooth motion. Rated for a dynamic radial load capacity of 0.6 kN and a maximum speed of 10,000 RPM (lubricated with grease), it suits applications like conveyor systems, furniture casters, or industrial jigs. Constructed with a carbon steel outer ring and inner race (stainless steel optional for corrosion resistance), the bearing includes a 0.3 mm fillet radius (r) for easy shaft/housing installation. Its unflanged design allows flush mounting, while a standard radial internal clearance (CN class) accommodates thermal expansion. Ideal for light-duty transfer applications, the CY-12B balances durability and maneuverability with dimensions tailored for miniature machinery and DIY projects.

 

 

Product Application

1. Industrial Automation & Machinery
In manufacturing, CY-12B serves as a critical element in conveyor systems and assembly line jigs, enabling smooth pallet transfers and precise part positioning. Its unflanged design and low friction (via phenolic cage and chrome steel balls) reduce energy consumption, making it ideal for lightweight automation modules—such as those in electronics assembly or small-parts sorting. The bearing’s corrosion-resistant stainless steel variant (optional) further adapts to humid or dusty environments, like food packaging lines or textile machinery, where reliability is non-negotiable.
2. Logistics & Material Handling
For light-duty conveying solutions, CY-12B is embedded in modular roller tables or cartons, facilitating frictionless movement of boxes (≤10 kg) in warehouses or retail backrooms. Its flush-mount capability suits retrofit projects, such as upgrading manual trolleys to semi-automated systems. In mobile equipment, like hospital bed trays or service cart shelves, the bearing’s 10,000 RPM tolerance ensures quiet, vibration-free operation, enhancing user experience in healthcare and hospitality settings.
3. Civilian & DIY Innovations
Home and furniture applications highlight CY-12B’s adaptability: it’s integrated into cabinet/drawer slides (e.g., kitchen pull-outs, office desks) to eliminate sticking, or as caster wheels for lightweight furniture (e.g., plant stands, DIY workbenches), combining maneuverability with load stability. Hobbyists and makers favor its affordability and ease of installation—paired with 3D-printed brackets, it transforms prototypes like robotic arms or camera sliders into functional, low-cost solutions.
4. Specialized Equipment & Prototyping
In medical devices, the bearing’s precision (CN-class clearance) supports adjustable armrests or biopsy table accessories, balancing hygiene (stainless steel option) and motion control. For automotive aftermarket use, it replaces worn bushings in steering linkages or sunroof mechanisms, offering a cost-effective fix without compromising durability. Even in educational robotics, CY-12B’s compact size fits student-built grippers or mobile platforms, bridging theory and practical mechanics.
