Key Features
Small Friction Coefficient
Rolling friction resistance between rolling elements and the raceway is minimal, effectively reducing energy loss and enhancing mechanical efficiency.
High Limit Speed
Optimized internal structure design allows stable operation at higher speeds, making it ideal for high-speed rotating equipment.
Moderate Load Capacity
Composed of inner ring, outer ring, rolling elements, and cage. This design provides high reliability and low maintenance costs.
Simple Structure
Streamlined component integration delivers durability, balanced performance, and cost-effective operation over a long service life.
Easy Installation
Low installation space and process requirements allow quick fitting into shafts and bearing seats with minimal downtime.
Applications
Industrial Equipment
Widely used in small motors, fans, and water pumps requiring radial and axial support with low friction and high-speed operation.
Office Equipment
Utilized in copiers and printers within transmission units to ensure smooth, low-noise, and precision transmission.
Household Appliances
Fitted in air conditioners, washing machines, and electric fans, adapting reliably to variable loads and operating environments.
Small Machinery
Perfect for small woodworking and food processing machines requiring high rotational accuracy and stable speed capacity.
Structure & Components
Inner and Outer Rings: Usually made of high-carbon chromium bearing steel (GCr15), quenched and precision ground for maximum hardness and wear resistance. The raceway surface ensures smooth rolling element circulation. The inner ring mounts to the shaft, and the outer ring seats within mechanical housings.
Rolling Body (Steel Balls): High-precision steel balls adhering to strict diameter tolerances. Balls rotate within inner/outer raceways to transfer radial and axial loads while facilitating rotational motion.
Cage: Typically made of stamped steel plate, brass, or nylon. Evenly spaces the rolling elements to prevent contact friction and guide smooth motion across raceways.
Packaging & Delivery
Packaging Details: Standard export packaging or customized according to customer requirements.
