Application areas: Widely used in precision bearings, valves (opening and sealing), medical equipment (high cleanliness requirements), chemical equipment (pumps, mixers, corrosion-resistant key), automotive components (steering, transmission), precision instruments and meters (measurement, guidance), and consumer goods (bicycles, hardware, kitchenware accessories).
Product function: The core function is to provide low friction rolling support (bearings), achieve reliable sealing and fluid control (valves), transmit motion and force (transmission system), or serve as wear-resistant media and fillers (grinding, chemical).
Key features:
Material: Mainstream 304 (universal), 316/L (high corrosion resistance, medical/chemical), 440C (high hardness and wear resistance). Procurement needs to clarify the selection of materials for working conditions (corrosiveness, strength).
Hardness: directly affects wear resistance and load-bearing capacity (such as HRC 58-62 commonly found in bearing grades). Need to match the application load.
Accuracy (Grade G): Diameter tolerance, sphericity (roundness), and surface roughness (smoothness) are core indicators (such as G10-G100). High precision ensures smooth operation, low noise, and long lifespan.
Corrosion resistance: determined by material and surface treatment, it is crucial for chemical, medical, and food grade applications.
Temperature resistance: Specific high-temperature applications require attention to the high-temperature performance of the material.
Consistency: Stable size and performance between batches are the foundation for ensuring assembly quality and efficiency.
