Last time this came up, I copied all the relevant bits of the post and saved them. Here goes:
——————————————————–
Time pedal bearing replacement
(whilst still on the bike) Take the end cap off, undo the nut on the end of the axle, pull the body of the axle (why you left it on the bike, as it’s a lot easier). Knock out the bearings and bushing pop in the replaceement units and bolt it all back together.
You will find that the Atac bearing in your pedals are made from Stainless steel, whereas standard bearings are carbon steel. Stainless bearing will last a long time (like the originals)
I bought some stainless steel bearings from Simply bearings for around £10each
The details are 6x15x5mm ZZ stainless steel double metal shielded.
Also be careful when installing new bearing and tightening nyloc nut, i have broken an axle by overtightening
The details are 6x15x5mm ZZ stainless steel double metal shielded.can also be used on the Atac XS and XE models?
And also where to find replacement bushings for XS and XE models please?
I too have 2-3 pairs that are wobbling a fair bit and so far my Google Fu has failed to find a solution.

*Caveat*
I didn’t order from here and you’ll have to check the dims with a calliper as I chucked mine away. However, this line seemed to fit the performance spec and they def have the size required. IIRC they also have shock eyelet bush sizing in Imperial.
For Atak Carbon XS and Z Control models the bearings are as listed above , 6x15x5mm ZZ stainless steel double metal shielded.
For Atak Carbon XS the bushings are Iglidur product number JSM1014-16, ie a 10mm shaft, through a 16 mm long (14 mm overall diam) bushing. Cost = 3.57 each. Plus £6:00 p+p.

For Z Control the bushings are Iglidur product number JSM1012-15, ie a 10mm shaft, through a 15 mm long (12 mm overall diam) bushing. Cost = 3.42 each. Again, plus £6:00 p+p.
