Explorer type bearing??

[MAGICPIE3FOCUSPOWER]

I would like to replace the bearing, after 200 km the bearing has some play.
You can hear knocking noise coming out the motor when turning the wheel.

So I am looking for 6917-2RS bearing.

But does it mean: a explorer type bearing?

Thanks!

Solved it's a open bearing

Do I have to C3 type bearing or just C0?

really?
You need to replace bearing after just 200kms, seriously?
They bearings must have been abused during installing?

Yup it's a GM motor
