Precision Grade Heavy Duty Double Row Angular Contact Ball Bearing 5203 2Rs C3 Measures 17mm X 40mm X 17.5mm Built Tough With Sealed Components For Smooth Electric Motor Upgrades

Sealed dual row bearing boosts steady motor rotation.
✔️ Grade ten balls. High carbon steel shell. 17 x 40 x 17.5 mm frame.

This durable rotary component supports heavy axial and radial forces in demanding setups. You will install it directly into blower housings, high speed centrifugal pumps, and transmission assemblies. The precision ground raceways reduce friction while keeping shaft alignment tight under rapid cycling conditions.

✅ Static load capacity reaches 2000 pounds for sustained operational stress.
✅ Dynamic load capacity measures 3100 pounds during continuous rotational cycles.
✅ Maximum rotational speed hits 11000 revolutions per minute without overheating seals.
✅ Factory packed with Mobil grease to maintain lubrication across varied temperature ranges.

💡 How do double row angular contact ball bearings extend machinery service life?

- You handle heavy thrust loads with a handy dual raceway setup that shares stress evenly.

- The preloaded inner rings lock shaft position firmly during rapid acceleration phases.

- Grease packed grooves wipe moisture away from metal contact zones on dirty job sites.

- Standardized mounting dimensions let you swap out worn units without machining replacement housings.
