Description
Basic Parameters
The Universal Ball Bearings: IA – 15 has an inner diameter following ISO 15 standard, which is typically 15 mm, ensuring compatibility with a wide range of shafts. It offers high precision with a dimensional accuracy at P4 level according to ISO 492, minimizing any deviations in size. In terms of rotational accuracy, it reaches P2 level, guaranteeing smooth and stable rotation. The bearing has a specific basic dynamic load rating, perhaps around 9 – 10 kN, enabling it to handle continuous dynamic loads during operation. Its basic static load rating might be approximately 4 – 5 kN, providing stability under static conditions. The bearing is pre – filled with high – quality grease for lubrication, reducing friction and wear, and is equipped with standard seals, likely of contact – type, to prevent the ingress of contaminants. With a suitable material, such as bearing steel for high strength and durability, and a possible galvanized stamped steel bearing seat, it can withstand various operating environments. The limiting speed of IA – 15 can reach around 9000 – 10000 r/min under h6 shaft tolerance, making it suitable for applications requiring relatively high – speed rotation.



Product Application
1. Transportation Industry
- In automotive applications, the IA – 15 can be used in the steering systems. Its ability to handle both radial and axial loads ensures smooth and precise steering operations. For example, in the linkages connecting the steering wheel to the front wheels, the Universal Ball Bearings IA – 15 can reduce friction, allowing for easy turning and enhancing the overall driving experience.
- In the railway sector, these bearings are suitable for use in the bogie systems. They can support the weight of the train cars while enabling smooth movement along the tracks. The IA – 15’s high – speed performance capabilities make it an ideal choice for high – speed trains, where minimizing vibration and ensuring reliable operation are crucial.
2. Industrial Machinery
- In conveyor systems, which are widely used in manufacturing plants, warehouses, and distribution centers, the IA – 15 can be incorporated into the rollers. These bearings help in the seamless movement of goods along the conveyor belt by reducing rotational resistance. Their durability ensures long – term operation without frequent maintenance, which is essential for maintaining high productivity in industrial settings.
- In machine tools, such as lathes and milling machines, the IA – 15 can be used in the spindle assemblies. The precision – engineered design of these bearings allows for high – speed rotation with minimal run – out, which is critical for achieving accurate machining of parts. This results in better – quality products and increased efficiency in the manufacturing process.
3. Household and Office Equipment
- In office chairs, the IA – 15 can be found in the swivel mechanisms. It enables the chair to rotate smoothly, providing users with easy mobility while sitting. The bearing’s ability to support the weight of the user and withstand continuous rotational movement makes it a reliable choice for this application.
- In household appliances like washing machines and dryers, the IA – 15 can be used in the drum – rotating mechanisms. These bearings help the drum spin at high speeds during the washing and drying cycles. Their resistance to corrosion and ability to handle dynamic loads ensure the long – term performance of the appliances.
4. Medical Equipment
- In medical devices such as imaging equipment (e.g., CT scanners and MRI machines), the IA – 15 can be used in the rotating components. The high – precision and low – noise operation of these bearings are essential in medical applications, as any vibration or noise could potentially affect the accuracy of the imaging results.
- In surgical instruments that require rotational movement, like some types of drills or endoscopic tools, the IA – 15 provides the necessary smooth rotation. Its small size and lightweight design make it suitable for integration into these compact and delicate medical devices.
