Single Pack Metric 6203 ZR Sealed Bearing
✔️ Heavy duty sealed unit, runs smooth under load at 17x40x12mm

This single deep groove ball bearing delivers steady rotation for industrial motors and power drills. The dual rubber faces lock in grease while blocking grit so your gearboxes last longer. Technicians mount these metric units where quick spin up and low upkeep save time.

✅ Precision ground inner and outer races
✅ Low friction contact minimizes energy loss
✅ Heat dissipation keeps operating temps down
✅ Rubber faces protect against dirt ingress

💡 Why do mechanics prefer sealed deep groove bearings for rotating assemblies?
Finding a handy rolling element for heavy shifts cuts downtime and keeps machinery running smoothly.
- Metric dimensions match standard motor frame sizes perfectly
- Rubber lip seals trap factory lubrication longer than open shields
- Steel construction handles radial loads without wobbling
- Smooth raceways reduce vibration during heavy startup cycles
