RETAINING RINGS - EXTERNAL - E BOWED

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

The External Bowed E-Ring compensates for accumulated tolerances on a shaft. Once snapped into the groove, these bowed rings exert a force or a "preload" on the retained parts made to the low side of the tolerances "snugging" everything up. They also act like a spring and "give" when parts made to the high side of the tolerances extend too far into the groove.

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)
