The good price sleeve bushing (also called wrapped bucket bushing) is a versatile, cost-effective component tailored for 20-50 ton excavators, including CAT320, KOMATSU PC220, and SANY SY215 models. It also serves as an OEM replacement for Hitachi 240 series excavators (240-3, 240-3G, 240-5A) with part number 4443883, making it a core solution for excavator bush and heavy equipment bushing applications. Engineered as the hinge point between buckets, booms, and arms, it withstands radial forces up to 80kN—supporting smooth excavation actions while cutting maintenance costs. Its balance of performance and affordability makes it a top choice for repair shops, equipment rental firms, and construction companies seeking reliable replacements.
Unlike brand-specific bushings, the sleeve bushing fits 20-50 ton excavators across top brands: CAT320 GC/GX, KOMATSU PC220-7/8, SANY SY215C-S, and Hitachi 240-5A. This versatility eliminates the need to stock multiple bushing types, simplifying inventory management and reducing storage costs.
Priced 20-30% lower than OEM bushings, this good price excavator bushing does not compromise quality. For short-term tasks (≤3 months, e.g., temporary construction), it outperforms expensive copper sleeves in cost-effectiveness while meeting basic wear requirements—ideal for budget-sensitive operations.
Equipped with a PTFE inner layer, the wrapped bucket bushing reduces friction coefficient to 0.04-0.06 (vs. 0.15-0.2 for uncoated steel) and blocks sediment (sand, soil) from entering hinge gaps. This prevents jamming in dusty/muddy conditions, ensuring consistent excavator performance and minimizing downtime.
The outer nylon layer (0.5-1mm thick) enhances impact absorption by 30-40% compared to cast iron bushings. It absorbs shocks from irregular materials (e.g., construction waste chunks), protecting the excavator’s frame and joints from damage and extending component life by 25-30%.
With a standard cylindrical design and dimensional tolerance of ±0.03mm, the sleeve bushing installs without specialized tools. Maintenance teams can replace worn units in 30-60 minutes, getting excavators back to work quickly and reducing project delays.
In residential foundation digging or trench backfilling with CAT320 excavators, the bushing resists wear from sand and clay. Its PTFE layer prevents sediment buildup, maintaining smooth boom/bucket movement even in wet, muddy conditions—critical for daily productivity.
When processing mixed waste (bricks, steel rods) with SANY SY215 excavators, the nylon coating buffers impacts from hard debris. This protects hinge components from dents, reducing repair needs and keeping equipment operational for longer shifts.
For light gravel/coal extraction with KOMATSU PC220 excavators, the bushing’s 40Cr steel core withstands repeated loading stress. It performs reliably during 8-hour daily shifts in small-scale mines, meeting basic wear resistance demands.
In road/pipeline maintenance (e.g., water pipe trenching) with Hitachi 240 excavators, the bushing’s phosphating treatment prevents rust from rain/dew. It maintains performance in long-term outdoor use, ensuring consistent operation in variable weather.
