RETAINING RINGS - EXTERNAL E-RINGS

Product Description

The E-Ring is perhaps the most popular and widely used radial retaining ring (so named because it is shaped like the letter "E"). E Rings have large "shoulders" and are ideal on small diameter shafts. The three prongs make contact with the bottom of the groove for effective retention.

Note: Hand Tools and Pneumatic Tools for installation are available. Please contact EFC-International directly for information.

Features and Benefits

External E-Rings are radically installed into machined grooves on shafts. They can accommodate applications with lower thrust loadings than those retained by axial retaining rings. They can be installed quickly and are available stacked. EFC INT'L offers these retaining rings according to specifications to meet inch, DIN metric, ANSI metric, and Japanese world standards.

MATERIALS:
Carbon Spring Steel (SAE 1060-1090/UNS G10600-G10900) High strength and reliability; Austempered to eliminate brittleness and ensure strength,
Stainless Steel (Armco PH 15-7 Mo) Extra strength; Corrosion-Resistant; Prevents atmospheric oxidation up to 900 degrees F; Minimal distortion; High ultimate tensile strength of 225,000 psi; High creep strength
Beryllium Copper (Alloy #25/UNS C17200) Conductivity; Excellent corrosion resistance, especially in sea air and sea water atmospheres

FINISHES:
Plain (No finish)
Phosphate Coating ( Carbon Steel Retaining Rings)
Zinc Plating (yellow dichromate post plating finish - 96 hour salt spray protection)
Mechanical Zinc Plating (For SAE 1060-1090 steel rings - eliminates hydrogen embrittlement)
Zinc Dichromate Lacquer (Corrosion protection of up to 240 hours of salt spray protection)
