Fein 41701000008 Spare Part - Grooved ball bearing

41701000008 supersedes older part numbers: 41701241126

Original Fein grooved (deep‑groove) ball bearing — part no. 41701000008. Compact precision bearing made for Fein power tools: inner diameter 5 mm, outer diameter 16 mm, width 5 mm (5 × 16 × 5 mm), single‑row deep‑groove design for smooth rotation and reliable radial support.

Why this part matters: it replaces the small shaft/armature support bearing inside the motor/drive assembly of Fein oscillating tools, restoring quiet, low‑vibration operation and correct shaft running clearance.

Typical fitment (examples): used in the Fein MultiMaster/FMM and FMT series — for instance FMM 350 Q / FMM 350 QSL and FMT 250 (QSL) style models — check your parts diagram for the exact location.

Key selling points:

- Genuine Fein part number 41701000008 — exact replacement for the original bearing.

- Metric specification: 5 × 16 × 5 mm — a standard small deep‑groove ball bearing for compact power‑tool shafts.

- Precision fit for motor/gear assemblies — reduces runout and noise compared with worn bearings.

If your oscillating tool is showing rough running, rubbing or increased vibration, swapping this genuine Fein grooved bearing back into the motor/head assembly will often restore smooth operation quickly.
