Excavator track rollers support heavy machinery weight and enable smooth track movement. Different excavator models require specific roller types and sizes based on track width, weight capacity, bearing design, and sealing. Canadian buyers can shop online for compatible, high-quality track rollers at the best prices with deals and free shipping options.
What Are the Main Types of Excavator Track Rollers?
Excavator track rollers include single flange, double flange, and carrier (top) rollers. Single flange rollers guide the track on one side, double flange rollers on both sides for better alignment, and carrier rollers support track tension from above. Each type suits different undercarriage designs and machine models.
How Do Track Roller Specifications Vary Across Excavator Models?
Specifications vary mainly by roller diameter, width, weight capacity, and bearing type. Larger excavators need wider, stronger rollers with heavy-duty bearings and advanced seals. Smaller models use compact, lighter rollers. Specifications must match OEM standards to ensure fit and durability.
Why Is Bearing Type Important for Excavator Track Rollers?
Bearings affect roller longevity and performance. Tapered roller bearings handle heavy radial and axial loads, reducing wear. High-quality sealed bearings prevent dirt and moisture ingress, extending roller life in harsh construction conditions.
Which Materials Are Used in Excavator Track Rollers?
Rollers are typically made from cast steel or forged alloy steel. Cast steel offers durability, while forged alloy steel provides enhanced strength and resistance to wear and impact, making them ideal for heavy-duty excavator models.
How Does Track Width Influence the Track Roller Selection?
Track width dictates roller size requirements. For example, an EX100 excavator with 100 cm wide tracks needs wider rollers compared to an EX30 with 30 cm tracks. Correct width ensures proper weight distribution and track stability.
Where Can You Buy Excavator Track Rollers Online in Canada?
Canadian online stores specializing in heavy equipment parts offer a wide range of track rollers compatible with major brands like Caterpillar, Komatsu, and Kubota. These stores provide competitive pricing, frequent deals, and often free shipping.
What Are the Differences Between Excavator and Bulldozer Track Rollers?
Excavator rollers generally have larger diameters and widths and enclose bearings to reduce debris ingress. Bulldozer rollers have reinforced structures with steel rims for heavy earthmoving. Understanding these differences helps select correct rollers for your equipment.
How Can You Ensure Compatibility When Buying Track Rollers for Your Excavator?
Match part numbers or OEM specifications carefully. Consult your machine’s manual or OEM catalogs for exact dimensions and bearing types. Choose suppliers offering precise OEM-compatible, precision-engineered rollers.
