Track sprockets — Drive sprockets for mini excavators

• Perfect fit with rubber tracks: Trasteel Track sprocket wheels are specifically designed to work with Trabber tracks, preventing slippage and ensuring consistent traction.
• Induction hardening: Each wheel undergoes a heat treatment process that provides high surface hardness without compromising core toughness.
• Optimized tooth geometry: The tooth profile is calculated to maximize engagement efficiency and minimize wear on both the sprocket and the track.
• High-performance steel: Made from special steels with excellent impact and abrasion resistance, adapted to tough working conditions.
• Debris protection: Design features limit the ingress of sand and debris between teeth, extending undercarriage life.

Sprocket wheels for rubber tracks: precision and strength

The sprocket gear wheels are one-piece components specifically designed for light machinery such as mini excavators, midi excavators and other equipment running on rubber tracks. Their toothed profile fits perfectly with the track pitch, ensuring stable and efficient traction.

• Easy installation: As monoblock parts, sprocket wheels are quick and precise to mount on the undercarriage structure.
• Optimized engagement: Teeth are designed to match the exact pitch of Trabber tracks, minimizing vibration and wear.
• High surface hardness: Heat treatment allows them to withstand continuous stress and reduce friction damage.
• Robust design: Resistant to impacts and abrasive particles, even in muddy, gravelly or sandy conditions.

Wear prevention and warning signs

Progressive wear of sprocket wheels is normal but can be prevented or minimized through proper maintenance. Some key warning signs to monitor:

• Worn or sharpened teeth: Indicates loss of proper engagement with the track.
• Unusual vibrations or noises: May point to misalignment between the sprocket and the track.
• Lateral wear: Often caused by embedded debris or incorrect track tension.

Regular visual inspections help detect these issues early and schedule timely replacements, avoiding further damage to the undercarriage system.

Maintenance of sprocket gear wheels

Proper maintenance ensures the reliable performance of the rubber track drive system. Here are some key recommendations to extend sprocket life:

• Simultaneous replacement: Change the sprocket wheel at the same time as the track to avoid premature wear on new components.
• Pitch verification: Ensure the sprocket pitch matches the track, especially after replacements.
• Prevent debris build-up: Keep the contact area clean to avoid unnecessary friction and localized wear.
• Alignment check: Proper sprocket and track alignment reduces lateral stress and improves system efficiency.

Maintenance and wear prevention

Progressive wear of sprocket gear wheels is inevitable, especially on job sites with continuous work and varying ground conditions. However, a good maintenance strategy helps prevent major issues and extends the undercarriage’s service life.

• Regular inspection: Check tooth condition and alignment to avoid irregular wear.
• Joint replacement: Replace the rubber track and sprocket at the same time to avoid pitch mismatch and prolong component life.
• Routine cleaning: Remove mud, gravel or abrasive materials between teeth to prevent excessive friction and localized breakage.
• Correct tension: Maintain proper track tension to avoid overload on the sprocket and reduce abnormal vibrations.

It’s also important to monitor some advanced wear indicators:

• Sharpened or worn teeth: Sign of pitch loss between sprocket and track, which can cause skipping or traction failure.
• Lateral flank wear: Common in soft or abrasive ground conditions such as sand or clay.
• Deformations or cracks: In welded areas or the main body, may indicate fatigue due to overload or impacts.
