Explanation of common parameters of spiral retaining rings

1.Bore Diameter: Also known as the “hole” diameter. This size represents the inside diameter of the device where the hole retaining ring is installed.
2.Shaft Diameter: Also known as the “shaft” diameter. This dimension represents the outside diameter of the device where the shaft retaining ring is installed.
3. Offset: This design characteristic refers to the bending of material at gaps. This provides a flat and level surface for easier installation.
4.Radial Wall: Width per side, measured from the inner edge to the outer edge.
5. Back-up Ring Thickness: The overall thickness of the edge-wound back-up ring. Multiply the material thickness by the number of turns and then add the wedge value to determine the overall thickness.
6. Material Thickness: Also known as “line” thickness. This dimension can be used to determine the overall thickness of the retaining ring.
7.Back-up ring axial load carrying capacity: the device can withstand a given axial load value (in pounds ) overall ability.The limit value is two mathematical
The smaller value of the calculated value: axial load carrying capacity of the retaining ring (PR)Or groove axial load carrying capacity (PG).
