SP-13 STEEL BALL INGCO (RH150028) E-46

What This Part Is

The steel ball is a small hardened steel spherical component used inside the internal mechanism of the rotary hammer. It works as a rolling element or fixture element in one or more locations where smooth motion, precise positioning, or locking action is needed.

Function in the Tool

In rotary hammer parts assemblies, steel balls typically serve as:

• Rolling/locating elements in shifting or indexing mechanisms (e.g., mode selector, gear positioning)

• Detent elements that provide tactile “click” positions when switching modes or engaging parts

• Bearing/guide support to reduce friction between metal parts that move relative to each other

• Locking elements that keep components aligned or interlocked during operation

Rotary hammer interior parts diagrams often show steel balls used in critical positions of the piston/gear or selector assemblies to ensure smooth operation and correct engagement.
