SP-2 STEEL RING 17.5*2 INGCO (RH150028) E-40

🧰 What It Is

The SP‑2 Steel Ring is a small, hardened metal ring used inside the internal mechanism of the rotary hammer. It typically functions as a retaining ring, spacer, or washer‑type ring that holds components in place and ensures correct spacing between moving parts.

Though small, this ring plays an important role in maintaining the structural position of adjacent parts under heavy vibration and impact loads inside the tool.

⚙️ Technical Function

This steel ring performs one or more of the following roles:

1. Retaining Function

• Fits into a groove on a shaft or inside a bore to prevent axial movement of components.

• Locks gears, bearings, or pistons in place so they won’t slide under load.

2. Spacer / Alignment

• Provides a precise gap between two parts to maintain correct alignment.

• Ensures that gears and moving parts remain correctly meshed and do not bind.

3. Load Distribution

• Helps distribute axial loads over a broader area, reducing wear on adjacent parts.
