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
