TransDrive Metric Circlips

Internal circlips, also known as retaining rings or snap rings, are used to fit inside a cylindrical bore or housing. They are designed to prevent lateral movement by pushing outward against the walls of the bore. This type of circlip is commonly used in applications where a part needs to rotate, spin, or pivot, such as in electric motors, turbines, pistons, and various vehicle components.

External circlips, also known as retaining rings or snap rings, are used to secure components on a shaft and prevent lateral movement. They are typically fitted into grooves on the shaft and serve as a shoulder to hold parts in place. These circlips are commonly used in applications where parts need to rotate, spin, or pivot, such as in electric motors, turbines, pistons, vehicle construction, and various machinery components like sprocket chains and roller bearings.

Stainless steel is a preferred material for circlips due to its durability and resistance to corrosion, making it suitable for various applications.

Heavy-duty external circlips are designed for applications requiring more robust performance due to their greater thickness and strength compared to standard circlips.

1. Thickness and Strength: Heavy-duty external circlips are thicker than standard external circlips. This increased thickness enhances the strength of the circlip, making it more suitable for heavy-duty applications where greater force and durability are required.
2. Design and Standards: Both standard and heavy-duty circlips follow the same basic design. Standard external circlips are typically made to DIN 471 standards, while heavy-duty versions are often made to DIN 1460 standards, which account for the increased thickness and strength requirements.
3. Material: Both standard and heavy-duty circlips can be made from materials like carbon steel or stainless steel, but the choice of material can vary depending on the specific application needs.
