Description of NTN Bearing 6303LUA Polyacrylic Clearance

Deep groove geometry for high speeds. Single row for supporting radial loads. Steel cage evenly spaces balls for reduced friction, vibration and noise. Rubber seal on the side of the bearing exposed to contaminants and open on the other for applying lubricant. CN (normal) radial internal clearance for applications that do not involve thermal expansion or atypical precision.

Faulty bearings for critical applications

I purchased these bearings for an important project but they failed within a few weeks of use. The quality is subpar and not suitable for industrial and scientific applications....

Pros
  • None
Cons
  • Low quality, unreliable

Incorrect part even if the part number is the same.

I buy this part number from other stores quite often and was looking for another place to buy so decided to visit one. When it arrived it's not the same as the ones I buy elsewhere. The description is correct after sighting, but I expected that the bearing is sealed on both sides. Not a bad product and the number on the bearing is the same as the bearings I buy from the bearing store but they are different.

Pros
  • Deep groove geometry for high speed
Cons
  • So far so good
