SALT Track vs. Dry Track: 3 Things to Consider Before You Buy

Choosing the right undercarriage track for your excavator or Dozer isn't always straightforward. If you're currently comparing SALT (Sealed and Lubricated Track) with traditional Dry track, you're likely weighing upfront cost against long-term performance.

Both options have their place. The key is knowing which one makes sense for your equipment, your operating conditions, and your bottom line.

Here are three factors to consider before you make a decision.

1. Initial Cost vs. Long-Term Value

Let's start with the obvious difference.

Dry track costs less upfront. If you're working with a tight budGet or need to get a machine back up and running quickly, dry track is the more accessible option.

SALT track comes with a higher initial price tag. But that's not the whole story.

With SALT track, lubricant inside the pin and bushing creates a fluid film that reduces metal-to-metal contact. Less friction means slower wear. In most applications, SALT track delivers 30-50% longer service life than dry track.

So the real question isn't "Which is cheaper?" It's "Which costs less per hour of operation?"

For equipment running continuous hours in demanding conditions, SALT track often works out to be the more economical choice over the full lifecycle.

2. Lifespan and Wear Patterns

Wear happens differently on dry track versus SALT track.

On dry track, the pin and bushing wear against each other directly. As they wear, the track pitch gradually extends. Eventually, the bushings wear thin, and the sprocket teeth start engaging differently. You'll need to monitor pitch extension and plan for replacement when it reaches the limit.

On SALT track, the lubricant film slows internal wear significantly. The bushing outer diameter still wears from contact with the sprocket, but the internal pin and bushing surfaces stay protected much longer.

That said, SALT track performance depends heavily on seal integrity. If seals fail and lubricant leaks out, wear accelerates quickly. This is why seal quality matters—not just at the time of installation, but throughout the track's service life.

3. Application Fit: Does Your Machine Need SALT?

Not every machine benefits equally from SALT track.

SALT track makes the most sense when:

• Your equipment operates continuously—multiple shifts, high hours per year

• Working conditions involve abrasive materials like sand, gravel, or rock

• You want to extend maintenance intervals and reduce downtime

• The machine is relatively new or has significant remaining life

Dry track may be the better fit when:

• The machine runs intermittently or has low annual hours

• You're working with older equipment where extended track life won't pay back

• Budget constraints are the primary consideration

• The application involves less abrasive conditions

There's also a practical consideration: SALT track requires proper seals to deliver its value. If seals are damaged during installation or if the track is operated in conditions that rapidly degrade seals, the expected lifespan advantage may not materialize.

Quick Comparison

Which One Should You Choose?

There's no universal answer—it depends on your specific situation.

If you're managing a fleet of machines running day and night in a quarry or mine, SALT track is worth the investment. The extended life and reduced maintenance downtime will likely pay back the higher upfront cost.

If you're maintaining an older machine that works occasionally on light duty, dry track gives you solid performance without over-investing.

And if you're somewhere in between? Consider the machine's remaining service life, your operating conditions, and your maintenance capacity. Sometimes the right choice is SALT on your primary production machines and dry track on backup equipment.
