anyone know if if there is a bearing the idler pulley on the front of the ac compressor?

My clutch side of the compressor is good but the pulley half is binding, I think it rusted the car sat for a year, it also ruined the alternator.

I'm hoping I can remove the front of the ac compressor and grease rather than replace I do not like messing around with ac systems.

this vid shows how to service but I'm not clear what the pulley rides on

 

ohh figured it out, I had a spare one in the garage I took apart, there is a bearing pressed into the pulley part of the compressor.

I'm just gonna swap out those parts with my spare, should be easy on car while I do the alternator
