ETW Retaining Rings (E-Type Circlips)

E-Type retaining rings are commonly used shaft components, designed to be mounted into grooves on the shaft surface. They serve to secure components in place and prevent axial movement, offering quick installation and stable retention.

Depending on application needs and international standards, E-type rings are available in three major variants:

​​

Japan｜JIS B 2805

  • Size Range: E0.6 – E30 (ø0.6mm – ø30mm)

  • Materials: S45C medium carbon steel, SUS304, SUS420

  • Remarks: Commonly used in Asia / Available in stock

​​

Germany｜DIN 6799

  • Size Range: ø0.8mm – ø30mm

  • Materials: S45C medium carbon steel, SUS304, SUS420

  • Remarks: For heavy-duty shafts / European standard equipment

​​

USA｜ANSI 5133

  • Size Range: 0.125" – 10"

  • Materials: S45C medium carbon steel, SUS420

  • Remarks: Suitable for American-standard equipment

​​

​

​Applications

  • Axial positioning for precision motor shafts

  • Retaining rings for springs and washers

  • Compact mechanisms and linear guide systems

  • Internal component fixation in bicycles and power tools

​

E型扣環安裝工具

E-Type Circlip Installation Tool｜

Three Functional Options

The E-type circlip tool is designed specifically for installing and removing axial-side retaining rings such as DIN 6799, JIS B 28045, and ANSI 5133. It is ideal for precision assemblies, electronic components, and small shaft structures requiring quick installation.

Unlike conventional circlips, E-type circlips require a dedicated tool to press them directly into or remove them from the shaft groove.

Sheng Fong offers three tool types to meet various work needs:

  • Installation-only Type: Optimized for high-volume assembly, ensuring stability and efficiency

  • Removal-only Type: Enhanced control at the circlip opening, enabling quick removal without damaging components

  • Dual-use Type: Combines both installation and removal functions, ideal for maintenance and general applications

​

📌 All tools are designed in a straight form, enabling precise operation in limited spaces, especially suitable for miniature parts and tight assembly areas.
