Tuvalu Track Bushing (Universal) For Steel Tracks Of Crawlers (Excavator, Dozer, Loader...)

These bushings are in-depth heat treated for maximum wear resistance. For mini-excavators, common options include outer diameters around 35mm-45mm and lengths from 90mm-230mm. Larger machinery, such as the PC200 excavator (46.4x30.6x108.3mm) or D7G bulldozer (71.3x48.8x175mm), requires high-strength, larger-scale bushings. Note: Please verify your specific OD, ID, and length using a vernier caliper to ensure a 100% precision fit.

Product Description

Track bushing sizes for heavy equipment (excavators/bulldozers) vary by machine weight, with common, smaller options for mini-excavators including outer diameters (OD) around 35mm-45mm and lengths from 90mm-230mm. Larger machinery, such as a D7G bulldozer, uses larger bushings, for example, 71.3mm x 48.8mm x 175mm. Measurements are based on OD, inside diameter (ID), and length. 

Key Considerations For Track Bushing Size:

  • Mini Excavator Examples: Typical sizes include 41.3x24.5x92mm, 35.05x182mm, 45.3x230mm
  • Large Machinery Examples: A PC200 excavator might use 46.4x30.6x108.3mm, while a D7G bulldozer uses larger 71.3x48.8x175mm sizes
  • Measurement Technique: Bushings are measured using a vernier caliper to determine the exact outer diameter, inner diameter, and overall length
  • Wear Factors: Track chain wear, which can be measured by stretching the track and measuring across five pins, impacts the effective, operational size of the bushing

For specific, accurate sizing, it is necessary to identify the machine model and, in some cases, the part number.
