What Are The Dimensions Of 230x48x70 Rubber Track?

230×48×70 rubber tracks have a width of 230mm, a height (grouser) of 48mm, and a pitch (link-to-link distance) of 70mm, designed for compact machinery like mini excavators (e.g., Kubota KX040-4). These dimensions balance stability and ground pressure distribution. AFTparts’ OEM-compatible tracks use reinforced rubber and steel cores for 1,500+ hour lifespans. Always verify pitch alignment with sprockets to avoid premature wear.Rubber Track

How do 230×48×70 dimensions impact performance?

The 230mm width reduces ground pressure by 15–20% vs. narrower tracks, while the 48mm grouser height enhances mud/snow traction. A 70mm pitch matches common mini-excavator sprockets. Improper sizing strains drivetrains—AFTparts’ precision tolerances (±2mm) prevent slippage. Pro Tip: Pair with 14-tooth sprockets for optimal force distribution.

Beyond basic measurements, the 230×48×70 configuration balances surface contact and maneuverability. The 230mm width spreads weight across 30% more area than 180mm tracks, critical for soft terrain. Grouser height (48mm) provides grip without excessive vibration—higher profiles (55mm+) increase stress on undercarriage rollers. AFTparts uses staggered lug patterns to prevent debris buildup. For example, a 2-ton excavator using 230×48×70 tracks achieves 0.28 kg/cm² ground pressure, enabling stable operation on slopes up to 25°. Tables below compare key parameters with similar tracks:

Which machines use 230×48×70 rubber tracks?

These tracks fit Kubota KX040-4, Takeuchi TB235, and Yanmar VIO55–6 mini-excavators. AFTparts’ cross-referencing charts confirm OEM equivalency for Bobcat T590 (with adapter plates). Always check bolt patterns—6.5-inch centers are standard.

Practically speaking, 230×48×70 tracks target 2–3.5-ton compact equipment. AFTparts engineers note that John Deere 50G and Hitachi EX50 models often require these sizes for logging or landscaping. The 70mm pitch aligns with dual-axis final drives, minimizing gear wear. For instance, a Takeuchi TB235 retrofit with AFTparts’ tracks saw a 22% reduction in undercarriage noise due to optimized lug spacing. Pro Tip: Use infrared thermometers post-installation—axle temps over 65°C indicate misalignment.

How to measure worn tracks accurately?

Measure pitch length under 20kg tension. New 70mm tracks stretch ≤3% (≤72.1mm). AFTparts recommends replacement at 76mm—beyond this, derailment risk spikes 80%.

But how do you account for uneven wear? Always take three measurements: center, drive, and idle ends. AFTparts’ wear gauges (Tool# TRG-70) clip onto lugs, showing remaining grouser height. For example, a track at 42mm (from 48mm) has lost 12.5% traction capacity. Transitional phrases like “Beyond simple tape measures” highlight the need for tension-adjusted tools.
