What size rubber track does the Kobelco SK50UR-2 use?
The Kobelco SK50UR-2 uses a 400x72.5Nx74 rubber track. Note the N (narrow guide) guide-lug type — other guide types won't seat correctly on the rollers. Always confirm against your current track or the machine's spec plate, since some units shipped with more than one option.

Yes — this track is matched to the Kobelco SK50UR-2 by size and tread pattern. If your machine has a serial break or factory option, send the serial number and we'll verify fitment before shipping.
Are these OEM or aftermarket Kobelco SK50UR-2 tracks?
OEM-grade aftermarket tracks built to factory fitment for the Kobelco SK50UR-2 — same dimensions and guide type, continuous steel-cord belt, at a better price than dealer OEM.
