Metabo 143190500 Spare Part - Felt Ring

Metabo 143190500 — genuine Metabo (felt ring). This is a small, precision-cut felt sealing ring used in the oscillating plate / sanding‑pad assembly of Metabo half‑sheet/random‑orbit sanders; the felt is factory-impregnated to hold lubricant and help seal and damp the bearing/oscillation area.

Designed to sit at the interface of the oscillating plate and counterweight (listed as position 44 on Metabo parts diagrams), it prevents lubricant loss, reduces dust ingress and helps maintain smooth, low‑vibration operation of the pad/plate assembly.

Fits (example models shown in Metabo spare parts lists): SR 356 (type 00356001), SR 358 (type 00358001) and related SR-series sanders such as SR E 359 / SRE357 — check your sander’s parts diagram to confirm the same part number and location.

If your Metabo sander’s oscillating plate shows lubricant loss, squeaking, or increased dust getting into the bearing area, swapping in this genuine Metabo felt ring 143190500 is a low-cost repair that restores sealing and damping for the pad assembly — a common replacement among parts for power tools.
