Genuine Bosch retaining ring (snap ring) 2916540015 — a stamped round‑wire retaining clip made to Bosch tolerances for secure axial retention inside rotary‑hammer assemblies. Nominal size: DIN 7993‑28 (nominal 28 mm); typical section/width is in the ~2–3 mm range as specified by the DIN 7993 round‑wire standard.

This part restores the original shaft/bore retention used in Bosch GBH 4‑32 DFR rotary hammers (listed in the GBH 4‑32 DFR parts diagram as item 2916540015 / 2.916.540.015), so it’s ideal when reassembling the hammer mechanism, bearing seats or collar assemblies.

Practical details: small, hard steel snap ring (round‑wire DIN 7993 style, nominal 28 mm), fits the corresponding groove to prevent axial play under hammering loads; sold as a single genuine Bosch replacement part for reliable fit and metallurgy. This makes it a straightforward repair part when you need precise parts for power tools to bring a worn or disassembled GBH 4‑32 DFR back to spec.

What’s included: one original Bosch 2916540015 retaining ring (2 916 540 015), ready for drop‑in installation during servicing.
