| Ball Bearings Feature |
Simple structure, low manufacturing and maintenance cost, easy to install and disassemble. Low-noise with strict controlling the quality of JITO bearing. Low friction resistance and less heat generated during operation, effectively improving system efficiency. Moderate load capacity: can bear radial load and certain axial load at the same time. Smooth raceway rolling reduces vibration and operational noise. Deep groove ball bearings are widely used across industrial machinery and daily applications. |
| Application | Industrial equipment, Office equipment, Household appliances, Woodworking machinery |
| Bearing Package | Pallet, wooden case, commercial packaging or as customers' requirement |
Key Features
Small Friction Coefficient
The rolling friction resistance between rolling elements and raceways is minimized, effectively reducing energy loss and elevating mechanical efficiency.
High Limit Speed
Optimized internal structure allows stable operation at higher speeds, perfectly suited for high-speed rotating equipment.
Moderate Load Capacity
Composed of an inner ring, outer ring, rolling elements, and cage to ensure durable radial and axial load support.
Simple Structure
Straightforward design provides high mechanical reliability, ease of operation, and remarkably low maintenance costs.
Easy Installation
Requires minimal space and standard tooling, enabling swift installation directly into shaft and housing assemblies.
Applications
Structure Components
Manufactured from high-carbon chromium bearing steel (GCr15). Quenched and precision ground for supreme hardness and wear resistance. Precision raceway finish facilitates fluid rolling. The inner ring fits securely on shafts while the outer ring seats inside the housing bore.
Engineered to strict dimensional tolerances and sphericity grades. Steel balls roll smoothly between raceways, carrying loads while sustaining efficient rotational dynamics.
Constructed from stamped steel plate, brass, or engineered polymer/nylon. Retains uniform spacing between rolling bodies to prevent collision and mutual friction while guiding ball tracks accurately.
