What Goes Into Every UltraTrack Track
Every UltraTrack rubber track is engineered with a multi-layer construction system designed for maximum service life under real jobsite conditions.
- Continuous Steel Cord Belt — A single continuously wound steel cable runs the full length of the track, eliminating splice points that cause premature failure. This is the same belting method used in OEM tracks.
- High-Tensile Steel Links — Drop-forged steel links engage cleanly with your machine's sprocket for smooth power transfer and reduced undercarriage wear.
- 100% Virgin Rubber Compound — Acid-washed steel cords are bonded through multi-stage vulcanization. No reclaimed or recycled rubber. The result is a track body that resists delamination, cracking, and chunking even under sustained heavy loads.
- UV and Ozone Stabilizers — Built-in antioxidants and antiozonants protect against sun and weather degradation, extending track life for machines that sit outdoors between jobs.
Undercarriage Care: Getting the Most Hours from Your UltraDrive Rollers
- Check for Seal Leaks — Oil weeping around the end caps means the seal has failed. A roller that loses its oil runs dry, seizes, and then wears flat on one side. Replace it before it takes the track rail with it.
- Look for Flat Spots — Every roller should turn freely by hand. One that has stopped rotating develops a flat, scalloped face and grinds against the inner rail of the track on every pass.
- Keep the Undercarriage Clean — Packed mud, rock, and debris grind between the roller and the rail. Wash the undercarriage out at the end of each day, especially in clay or wet conditions.
- Check Track Tension — Over-tensioned track drives load straight into the roller bearings. Under-tensioned track lets the chain slap and wears the roller flanges. Use the sag measurement in the operator manual for your machine.
- Replace in Sets Where You Can — A new roller sitting beside worn ones carries more than its share of the load and fails early. Replacing across an axle or a side keeps wear even.
