Alternator Belt Tensioner Bearing - is this the right one

[JDB]

On the site that cannot be named is item number 320279985853 the right bearing to replace the one in the centre of the auto adjusting alternator drive belt?
Spec is :
6203 2RS Ball Bearing - New
BEARING MEASURES:
17mm(I.D)x40mm(O.D)x12mm(WIDTH)

Just at the price they seemed a bargain as others seem to be selling the same thing at £5 each?

is the pully squeeling the only reason i ask is bought a new bearing and fitted it but it turned out to be the pully was slightly of set .if this is the case then put a penny coin or washer behind the pully at a nine oclock position and it will  sort out the squeel.if this is not the problem just forget my post

This is on the auto tensioner and I am not sure I can get a coin behind it, knew that was the cure for the manually tensioned ones - but thanks.

AndyB - thanks for confirming.
