RETAINING RING TYPE - E

🔩 E-Type Retaining Rings | Types & Variants – Neo Fasteners

E-Type Retaining Rings, also known as E-Clips, are external retaining rings that slide radially onto a machined groove on a shaft. They offer quick assembly, low cost, and reliable retention in axial assemblies where space is limited.

At Neo Fasteners, we supply E-Type Retaining Rings in Stainless Steel (SS), Mild Steel (MS), High Tensile Steel (HT), Brass, and other materials, with finishes to match any industrial application.

📌 1. Standard E-Type Retaining Ring (DIN 6799 / IS 3075 Part 3)

• Most common E-clip
  
  

• Three-pronged design clips onto a groove in a shaft
  
  

• Standard: DIN 6799 / IS 3075-3
  
  

• Shaft Range: 0.8 mm to 30 mm
  
  

• Materials: SS 304, SS 316, MS (hardened), HT, Brass
  
  

• Finishes: Zinc Plated, Black Oxide, Phosphate, Passivated
  
  

📌 2. Heavy-Duty E-Type Ring

• Thicker cross-section for higher axial load capacity
  
  

• Used in gearboxes, automotive transmissions, heavy machinery
  
  

• Available in carbon spring steel and SS
  
  

📌 3. Miniature E-Clip / Micro E-Ring

• Designed for small shafts (as small as 0.8 mm)
  
  

• Ideal for electronics, miniature assemblies, model engineering
  
  

• Material: SS, Spring Steel
  
  

📌 4. Self-Locking E-Type Ring

• Includes internal dimples or ridges that offer a friction fit without the need for a groove
  
  

• Used in temporary or low-load applications
  
  

• Quick install/remove by hand or basic tools
  
  

📌 5. Reinforced E-Clip (Reinforced Shoulders)

• Modified E-ring with extra shoulder width for added strength
  
  

• Reduces deformation under high vibration or dynamic loads
  
  

• Used in motors, tools, and rotating shafts
  
  

📌 6. Crescent or Bowed E-Clip

• E-clip with a spring tension curve to apply preload or compensate for end play
  
  

• Useful in assemblies with vibration or thermal expansion
  
  

📌 7. Double E-Type Retaining Ring

• Dual E-clip style in a single component for double retention
  
  

• Used in axial components requiring locking from both sides
