17mm Bore 6203LLH Sealed Ball Bearing High Speed Radial Load
✔️ 17mm bore, 40mm OD, 12mm wide, steel cage double seal

This handy single row deep groove ball bearing handles radial loads while spinning up to high speeds. The double rubber seals lock in your grease and shut out dust so the bearing lasts longer. You will notice less vibration and noise when you install this unit on motors, pumps, or gearboxes. Its 17mm bore fits standard shafts for reliable power transmission.

✅ Deep groove geometry supports high rotational speeds without overheating.
✅ Steel cage keeps balls spaced evenly to cut down on friction and noise.
✅ Non-contact rubber shields protect the interior from debris and hold grease tight.

💡 What is a sealed ball bearing used for in high speed applications?
A sealed ball bearing keeps contaminants out while handling radial forces during fast rotation.
* Double rubber seals trap lubricant inside and stop dirt from damaging the inner raceway.
* Deep groove design allows the unit to manage radial loads efficiently while turning at top RPMs.
* Steel cage construction minimizes friction heat buildup for stable performance under constant motion.
