Internal Retaining Rings with Internal Tooth-DIN984

The main function of the internal retaining rings with internal tooth is to stop the axial movement of the parts assembled in the hole. The internal tooth part can withstand a certain degree of impact to achieve the blocking effect.

Material: conventional carbon steel and stainless steel (65Mn, C67S, 2Cr13, 304, 1.4122, etc.)

Surface treatment: all kinds of conventional standard treatment, such as phosphating, Dacromet, Jumet, zinc plating, zinc nickel plating, electrophoresis, and so on.

Internal Retaining Rings with Internal Tooth-DIN984 Industry knowledge

From Carbon Steel to Stainless Steel: Customizable Solutions with DIN984 Retaining Rings

The Importance of DIN984 Retaining Rings
The primary purpose of DIN984 Internal Retaining Rings with Internal Tooth is to prevent axial movement of parts assembled within a hole. These rings feature an internal tooth design that enhances their gripping strength, allowing them to withstand significant impacts while maintaining their position. This makes them indispensable in industries such as automotive, aerospace, and heavy machinery, where precision and durability are non-negotiable.

By securely locking components in place, DIN984 retaining rings reduce wear and tear, minimize downtime, and improve the overall efficiency of mechanical systems. Their ability to handle challenging conditions ensures consistent performance even in the most demanding environments.

Material Flexibility for Every Application
One of the standout advantages of our DIN984 Internal Retaining Rings With Internal Tooth is the variety of materials available, ensuring they can be tailored to suit specific operational requirements. Our material options include:

Carbon Steel: Known for its strength and cost-effectiveness, carbon steel is ideal for general-purpose applications. Variants like 65Mn and C67S provide excellent tensile properties and resilience.
Stainless Steel: For applications exposed to moisture, chemicals, or extreme temperatures, stainless steel options such as 304, 2Cr13, and 1.4122 offer superior corrosion resistance and extended service life.
This flexibility allows customers to choose the perfect material based on factors such as budget, environmental conditions, and performance expectations.

Advanced Surface Treatments for Enhanced Durability
To further optimize the performance of our DIN984 retaining rings, we offer a range of advanced surface treatments. These treatments not only protect the rings from environmental factors but also enhance their appearance and functionality. Options include:
