No prob! Any 6001 bearing will fit, but you will want seals/shields too. A straight 6001 bearing will have open races. You'll need the suffix designation as well. "RS" means rubber seal on one side. "2RS" is robber seal on both sides. "Z" designates a metal shield or "seal". "ZZ" or "2Z" is shielded on both sides.
Rubber provides a better seal, but metal shields offer way lower rolling resistance. I'd opt for 6001 ZZ/6001 2Z. They are the same bearing
You could go for 6001Z (single shield/one side only) for even lower resistance, facing the open sides inwards, but you would have to service your bearings frequently, and that's not so bueno for cartridge bearings.
