SP-25 RING INGCO (RH150028) D-71

🧰 What It Is

The SP‑25 Ring is a metal ring used inside the internal assembly of the INGCO RH150028 rotary hammer. In hand power tools, “ring” parts usually serve as retaining rings (circlips), spacer rings, or washers. They keep adjacent components correctly positioned and secured on shafts or within housings.

⚙️ Technical Function

Depending on its exact position in the mechanism (diagram reference D‑71), this ring typically performs one or more of the following roles:

1. Retaining / Securing

• Holds components in place on a shaft or within a bore

• Prevents axial movement of gears, bearings, or other rotating parts

2. Spacing / Alignment

• Maintains precise axial clearance between adjacent parts

• Ensures correct engagement of gears or moving parts

3. Load Distribution

• Acts as a load spreader between surfaces, reducing wear

• Helps maintain stable motion under impact and vibration
