Frequently Asked Questions
What size rubber track does the Kobelco SK50UR-1 use?
The Kobelco SK50UR-1 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.
Will this track fit my Kobelco SK50UR-1?
Yes — this track is matched to the Kobelco SK50UR-1 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.
How do I confirm the right track size for my Kobelco SK50UR-1?
Read the size stamped on the inside of your current track, or measure width x pitch x links. Not sure? Message us and we'll match it.
Directional or block tread — which should I run?
For mixed dirt and gravel, most Kobelco SK50UR-1 owners run a directional (multi-bar) tread for traction and mud release. Block tread wears better on hard surfaces and pavement.
How long do Kobelco SK50UR-1 rubber tracks last?
Most rubber tracks last 1,200–1,600 operating hours depending on terrain, alignment, and tension. Keeping tracks tensioned and clearing debris daily extends life.
