Makita ROLLER 20 5903R/5603R/5604R - 415438-0
Original Makita replacement roller (part no. 415438-0) — a direct-fit roller for the lower guard assembly on several Makita circular saws. Compact and low-profile, it’s listed by Makita as "ROLLER 20" and is the part that the blade-guard rides on to roll smoothly over the cutting surface.
Key details: nominal roller size is described by Makita as 20 (listed as ROLLER 20), and it mounts on the matching 6 mm roller pin (Makita part 415437-2) shown next to it in the parts diagram — replace the roller and pin together if the pin is worn. Supplied as the single genuine Makita part number 415438-0.
Fits (examples): this roller is used on a range of Makita circular saw models — examples include 5143R, 5603R, 5604R, 5704R, 5903R, 5103R and 5017RKB, and appears in parts diagrams for 5740NB / N5900B.
Why choose this part: using the original Makita 415438-0 restores proper guard movement and reduces binding or catching when the saw is pushed through material — a simple, affordable replacement that gets the guard rolling true again.
