This setup is all new to me, and Im lost. Trying to install my rotor and caliper. I have slider type calipers. Now that my 11.75 rotor wheel bearing races are installed, Im ready to put the bearings in and then onto the spindle. But, I cant figure out which way my oil seal is supposed to be facing, some directions I found say point the lip of the seal inwards, but I dont know which side is the lip or what direction inwards means.

here is the back of my rotor:



Now which way does the oil seal go into the rotor? pic 1 or pic 2??
