Structural Characteristics

Stainless Steel Material: High-quality stainless steel is used, which has excellent corrosion resistance. In harsh environments such as humid conditions, and those with acid and alkali, it can effectively prevent rusting, ensuring the long-term stable operation of the bearing. It is suitable for fields like food processing and marine engineering.
Angular Contact Design: The contact angle is usually between 15° and 25°, endowing the bearing with good axial and radial load-bearing capacities. It can cope with complex forces, such as the multi-directional forces generated during the cutting of a machine tool spindle, ensuring the precise operation of the equipment.
Precision Manufacturing: The inner and outer rings as well as the rolling elements are of high machining precision with smooth surfaces. Strict process control ensures dimensional accuracy, ensuring a tight fit with the matching components and reducing operation friction and wear.

Performance Advantages

Stable and Durable: The combination of material and process results in a long service life and high reliability, reducing the downtime costs caused by frequent replacements and maintaining the continuous and efficient operation of the equipment.
Accuracy Assurance: The high-precision structure meets the requirements of precision equipment. During rotation, the radial runout and axial play are small, providing precise support for precision measurement and machining.
Adaptability to Diverse Working Conditions: With both corrosion resistance and strong load-bearing capacity, it can work in chemically corrosive environments and withstand impacts from different loads, making it widely applicable.

Application

The bearings can be used in the following industries

Food and Beverage Processing: Since the parts in contact with food ingredients need to be corrosion-resistant to ensure food safety, this bearing is used in equipment such as mixers and filling machines, and its stable operation contributes to efficient production.
Marine Equipment: In ship rudders, seawater desalination devices, etc., which face the corrosion of seawater and complex forces, the reliable operation of the bearing ensures the normal operation of the equipment.
Precision Machine Tools: It provides support for the spindles of CNC lathes and grinding machines, meeting the requirements for high-precision machining of parts and improving the technological level of the manufacturing industry.
