Standard of no ear Spiral External Retaining Rings No Mold Cost for shaftDescription:Our spiral retaining ring has no interference in assembly and an inner diameter that is burr-free. It allows manual and automatic quick installation and removal. External spiral snap rings are typically specified for heavy duty or shock loaded applications and are a standard choice in automotive and heavy equipment industries.
Advantages of external spiral snap ring- No need to assemble/disassemble the lugs, radial space saving;
- Edges with rounded corners, no punching burrs;
- Square edge wire for sharp edge installation;
- No need for special tools for installation and disassembly;
- Higher ring shear;
- Special terminals for specific applications;
- Heavy duty parts for higher rotation capacity;
General description:The unique design of the 2 turn external spiral snap ring provides a strong and flexible 360 degree fixation surface. They reduce the number of parts required and eliminate redundant machining such as countersinking, threading and drilling. Internal and external series retaining rings use standard industry groove sizes and are interchangeable with many stamped retaining rings. This series is suitable for thrust loads requiring deep groove, heavy section capacity.
