Rollers for Excavators

• Reinforced flanges: Designed to withstand continuous pressure and sliding during machine operation.
• Specialized heat treatment: Advanced treatments provide outstanding wear resistance.
• CNC precision: Manufactured with cutting-edge technology for a perfect fit and high-precision finish.
• High-quality materials: Made from top-grade steel and BI-metal bronze bushings for superior strength and durability.
• Unique sealing system: Equipped with high-quality seals that prevent dirt intrusion and retain internal lubrication, maximizing service life.

Bottom Rollers

Bottom rollers play a critical role in lifting the undercarriage and distributing the load. They're designed to resist wear from rough terrain and heavy-duty operations. Their reinforced structure helps the machine maintain correct height and prevents damage to other components like the track tensioner.

• Thick shaft: Reinforced to support the machine’s load with increased bearing capacity.
• Optimized tread band: The roller diameter is tailored to meet the demands of excavators and bulldozers.
• Enlarged oil reservoir: Bulldozer bottom rollers feature a larger oil chamber for better cooling during movement.

Top Rollers

Top rollers are essential for supporting the chain and track shoes. Built to withstand continuous wear, they ensure smooth and efficient machine operation.

• Wear patterns: Tread or flange wear may indicate the need for roller replacement.
• High-quality seals: Preserve internal lubrication, reduce friction, and extend the life of top rollers.
• Jam prevention: Designed to resist mud and sand build-up—common causes of roller jamming and failure.

Roller Maintenance

Proper roller maintenance is essential to ensure optimal performance and prevent damage to other undercarriage components. Here are some key tips:

• Regular lubrication: Check roller lubrication frequently to ensure smooth operation and avoid premature wear.
• Visual inspections: Periodically check for signs of wear on the tread or flanges.
• Daily cleaning: Keep the undercarriage free of sand and mud to prevent top roller jamming.
• Timely replacement: Replace worn or damaged rollers to avoid further undercarriage damage.

Wear Indicators

It’s important to identify wear patterns on top and bottom rollers to prevent serious undercarriage issues. Here are some key indicators:

• Flat rollers: Typically indicate that a top roller has seized, often due to mud or sand build-up.
• Tread wear: Visible wear on the roller tread signals the need for detailed inspection and possible replacement.
• Oil leaks: Indicate failed seals that should be replaced immediately.
