Not really. Regular skate- bearings take more of a beating so I tend not to buy overly expensive ones. A long board should definitely get some nice speed bearings. If you clean them regularly and keep them lubed they'll last you forever. DON'T USE WD40 TO LUBE THEM. For cleaning it's ok... because it helps protest them from rust and wear. You can actually buy a specific lube wherever you get the bearings.
