Have you tried blowing out the mechanism with a compressed air nozzle? Frequently this friction is caused not by the bearing itself but instead by debris, sawdust, etc. built up inside the base of the saw. I'd give it a good cleaning to begin with.
If that doesn't work, try applying bearing lubricant directly to the bearing races.Use an extension straw if needed so you can get to them, as this is designed to penetrate where even the reliable old wd40 may not reach. You can find this a specialty woodworking stores, as well as some well-equiped home centers.
Let us know if this works, or you've already solved the problem...

How do I replace the linear ball bearing on a c8fb2 Hitachi miter saw


Its not too difficult:
1) There are 2 retainer pins located on the rear slide support (#4 on breakdown) - carefully drive these out with a punch - be careful to support the bracket so you don't break it.
2) remove the rear support and slide the saw head and arms out of the bearing.
3) Remove the 2 covers (front and rear) over the bearing
4) loosen the allen head set screw on the housing that holds the bearing in place
5) using a large socket and a plastic hammer - gently tap out the old bearing.
Reverse process to replace.
Do not use grease or oil on the bearing or slides - use a pure, clear silicone spray that dries completely - grease & oil attract & hold dirt and debris and will cause bearing failure.
