中文简体DIN 472 Elastic Rings for Bores offer a simple and efficient solution for the axial retention of components within universally used bores in automotive assemblies. These internal retaining rings are easily installed and provide a secure shoulder for transmitting axial loads.
Key Advantages for Your Automotive Applications:
- Secure Axial Retention: Manufactured to DIN 472 standards, these elastic rings provide reliable axial retention of components such as bearings, gears, and shafts within automotive housings and bores. They effectively prevent movement along the axis, ensuring the integrity of the assembly under various operating conditions.
- High Axial Load Capacity: DIN 472 rings are designed to withstand significant axial forces exerted by the retained components. This robust retention capability is crucial in automotive applications where components are subjected to considerable thrust loads during operation (e.g., in transmissions, axles, and engine components).
- Space-Saving Design: As internal retaining rings, DIN 472 rings are installed within a groove inside the bore, resulting in a compact and space-efficient design compared to external retaining methods. This is particularly advantageous in the space-constrained environments often found in automotive assemblies.
- Easy Installation and Removal: These rings are designed for relatively easy installation using specialized pliers that compress the ring for insertion into the groove. Similarly, removal can be achieved with appropriate tools, simplifying assembly and disassembly processes during manufacturing and maintenance.
- Versatile Application: DIN 472 rings are available in a wide range of metric sizes (typically from 3 mm to 300 mm bore diameter, as per common industrial catalogs) and materials (including spring steel and stainless steel, often with surface treatments like phosphate or zinc plating for corrosion resistance), making them suitable for diverse automotive applications with varying load, environmental, and material compatibility requirements.
- Cost-Effective Solution: Compared to more complex fastening methods, DIN 472 elastic rings offer a cost-effective and reliable solution for axial retention in numerous automotive applications.
Ideal for Automotive Applications Such As:
- Bearing Retention in Housings: Securely retaining ball bearings, roller bearings, and needle bearings within automotive transmission cases, differential housings, and wheel hubs.
- Gear and Sprocket Positioning on Shafts: Providing axial fixation for gears, sprockets, and pulleys on shafts within automotive powertrains and auxiliary systems.
- Seal Retention in Bores: Holding oil seals, grease seals, and other types of seals in place within automotive components to prevent leakage.
- Valve Stem Retention: Securing valve stems within engine cylinder heads.
- Piston Pin Retention (in some designs): Providing axial retention for piston pins within connecting rods.
- General Axial Fixation: Used in various other automotive sub-assemblies where axial movement of components within bores needs to be prevented.
