The Husqvarna 738220419 Ball Bearing is a genuine OEM replacement component built for Husqvarna concrete core drills and floor grinders, including the DM280, DM340, DM650, DM700, DM1PACE, DMS280, PG680RC, and PG820RC. This Ball Bearing is manufactured to Husqvarna's exact dimensional and load tolerances, ensuring smooth, low-friction rotation that the machine depends on for consistent performance under demanding conditions. DHS Equipment supplies this part to help keep your equipment running when a bearing replacement is needed.
Key Features
- OEM Precision Tolerancing — Manufactured to Husqvarna's exact radial clearance and load specifications, this Ball Bearing delivers the low-friction rotation that high-torque drill motors and floor grinder spindles require.
- Drop-In Replacement Fit — Engineered to match the original bearing's dimensions and seating, this component installs directly into the bearing housing without machining or adaptation.
- Broad Model Compatibility — Fits a wide range of Husqvarna concrete core drills — DM280, DM340, DM650, DM700, DM1PACE, and DMS280 — as well as PG680RC and PG820RC floor grinders.
- Sustained Rotational Performance — A worn or failed bearing causes excessive heat, vibration, and spindle play that can damage surrounding components. Replacing it restores clean, stable rotation and protects the drive train.
A ball bearing supports and locates a rotating shaft while minimizing friction between the moving and stationary parts of the machine. In core drill motors such as the DM series, bearings carry the radial and axial loads generated during drilling, keeping the spindle centered and stable under the pressure of penetrating concrete. In floor grinders like the PG680RC and PG820RC, they support the grinding head drive, allowing smooth, consistent rotation at operating speed. When a bearing wears out, symptoms typically include vibration, unusual noise, overheating, and loss of concentricity — all of which accelerate wear on adjacent components if not addressed promptly.
