## Product's reviews:
- Prompt & great service - As usual MRO Supply team are quick in shipping the ordered parts correctly without any delay.. Will shop online again confidently knowing they offer very good and prompt service!
- Thanks mro - Right part fast shipping. Thanks
- Delivery time - Awesome delivery time on this type of bearing.
- Bearings - Order arrived on time, could have been packed a little tighter as the boxes the bearings came in were tore up. All is good as i used all of them instead of leaving them set in inventory.
