What is E clip? | How to determine E-clip size? | What is an E ring?

The clips are used all over the world for different applications. There are multiple types of circlips designed according to the nature of different applications. The circlip is, also called a snap ring or C-clip, is a retaining ring with an open end that snaps into its place. These are clips that fit into radial slots in the shaft and bore and are held firmly in place by springs. An E-clip is a most commonly used type of circlip. This article mainly explains the E-clip.

The circlip, which has E shaped design, is known as an E-clip. The E-clip is also called a ring clip or E-ring. The E-clip is the most famous type of external circlips. This clip resembles an “E” shape. It has an opening on one side.

The maximum circlips have a “C” shaped design. This design permits them to inflate when installed around the shaft or compressed when installed in a hole.

E-clips are tools most commonly used on devices like locking mechanisms and car engines. These are large circlips that hold components onto the shaft when positioned in a slot.

Standard retaining rings or circlips are available in two types:

  1. External retaining rings
  2. Internal retaining rings

The internal retaining ring installs into the hole groove, while the external retaining ring designs to fit the outer groove tightly on the rod or shaft. These clips use to exchange the need for mechanical fasteners (rivets, cotter pins, nuts, etc.) and often decrease the assembly weight. These have a long-life cycle.

How To Remove E Clips?

A small flat-bladed screwdriver, needle-nose pliers, or clip removal tool is most commonly used for removing an E-clip.  Clutch the E-clip with your tool and force it upward with reasonable pressure.

Follow the below-given methods to remove the E clip:

1) Use of E-clip Remover

  • First of all, properly align the removal tool with the E-clip end. Mostly the clip removers have curved, smooth edges. Ensures a parallel alignment of the E-clip curve with the curved edge of the tool, then position the tool directly under the clip. The E-clip removers have multiple types, but you can use all the tools in the same way.
  • Push up to put on an even, moderate pressure. After aligning the tool with the E-ring, slide the tool out of position. Be careful about the pressure during this process, and don’t apply high pressure. If you employ high pressure, the e-clip can fly off.
  • Store the E-Clip in a dry area so that you can reuse it next time. Put the E-Clip in a storage container, container, or storage You can use it again and again in other projects with the tool.

2) How to Remove E-clip with Pliers

  • Turn the E-Clip center sideways so that you can hold it easily. Turn the curved side of the E-clip toward you so that you can remove it easily.
  • Twist the clip by using needle nose pliers or your fingers. Twist the clip at such an angle that it can easily slide with moderate pressure.
  • Use needle-nose pliers to catch the E-clip center. Press the E-clip center with the tip of the pliers. Grasp the pliers strongly and eradicate the clip.
  • A needle nose plier is ideal for easily removing the E-ring. But you can also employ locking pliers or slip-joint pliers to remove the E-clip.
  • Apply moderate pressure to pull the e-clip toward you. While holding the clip, pull back the pliers to remove the E-ring from its place. If you are facing trouble gripping the E-Clamp, adjust the pliers in such a way that the tip becomes closer to the clip center.

3) How to remove E-clip by using a Flathead Screwdriver

  • First of all, make a proper alignment of the screwdriver with one of the smallest slots or grooves in the clip center.
  • Put the screwdriver tip into the clip groove. All types of E-clips have two small grooves in the center, one on the right and the second on the left. You may use both of these grooves to eradicate the clip. For excellent performance, use a screwdriver equal to the size of the E-clip.
  • Put your finger right next to the clip to grab it firmly as you move. Place the index finger of your non-dominant hand on top of the clip. This will prevent the e-clip from flying too far when you remove it.
  • Using moderate pressure, push the screwdriver upward. Grasp the screwdriver with your dominant hand and continue to push the tool up. In this way, the clip will remove easily. If not, apply a little bit more pressure.

Size of E-Clip

A common size of the E-clip is the highest groove diameter for which the clip is planned. The width of the throat and the free diameter are also vital dimensions used to measure the clip size.

The free diameter is the outside diameter, while the width of the throat is the size of the opening. These can be precisely measured with a relaxed ring clamp.

Construction Material

Different materials are used for the construction of E-clip according to the corrosion resistance requirements for the system. Most E-clips are made of alloy steel, carbon steel, stainless steel, and copper. These parts are used in various industrial machines and tools.

Applications of E Clip

The E-clips are most commonly used in a variety of machines, from simple hand tools to multipart airplanes. These clips also commonly use in railroad and transport systems due to their easy removal and installation.

Advantages and Disadvantages of E-Clip

The main advantage of the E-clip is that it has easy removal and installation. You can easily push it into a milled slot without any special tool, but a screwdriver or simple pliers are required to push it in or out of the shaft.

These clips don’t need a round shaft. Generally, these clips offer more functionality than other fasteners without the need for tapping, threading, or other machining tasks.

The E-clips have different types and sizes according to the application nature. The right size is vital for the retaining ring. It must deliver a tight fit to stop loosening.

The main disadvantage of the e-clip is that it has limited load capacity, which depends on the application requirements. However, the over-tightening of this clip may damage the shaft and reduce the assembly performance.

E Clip Vs Snap Ring

The main difference between e-ring and snap ring is given below:

  • The e-clip doesn’t require a round shaft and can easily press into the machined groove, while a snap ring requires a circular shaft.
  • The snap ring is stronger in thrust than the e-clip.
