Back-Up Ring Without Trunnion

Earless retaining rings (called Constant Section Rings abroad) are also called equal-section retaining rings. Because the cross sections are equal and there are no protruding ears of traditional stamped retaining rings, they are called earless retaining rings. The production, processing and usage characteristics of earless retaining rings and spiral retaining rings are similar. They are both made of flattened and wound steel wires. After heat treatment and surface treatment, they have good elasticity and toughness. Earless retaining rings are divided into two categories: shaft and hole, with various types of tail ends to choose from.
