For S/N #60001-#60052 3.Exact Installation Position The Komatsu-parts-195-30-69221 bogie minor is installed on the middle and rear sections of the left-hand and right-hand main track frame of D375 series mining bulldozers, fixed on the track beam through high-strength bolt groups, serving as the supporting base for the 2nd, 3rd and 4th groups of track rollers under full roller guard configurations. Each left and right track frame is equipped with multiple 195-30-69221 bogie minor units, each bogie matches with track roller axle component 17M-27-21711 installed in the inner cavity of the bogie body. During disassembly and replacement maintenance, technicians only need to jack up the bulldozer track assembly with heavy lifting tools, remove the fixing bolts of the bogie, then slide out the entire 195-30-69221 bogie minor directly without completely disassembling the whole long track frame, greatly simplifying field undercarriage maintenance work at mountain quarries and large open-pit mines. The roller mounting holes on the 195-30-69221 bogie minor are reserved with oil seal assembly grooves, which cooperate with matching sealing parts to form a fully closed lubrication chamber, blocking mineral dust, gravel fragments and muddy water from invading the track roller bearing cavity and avoiding premature roller abrasion caused by lubricant contamination. 4.Material & Production Craft Genuine Komatsu 195-30-69221 bogie minors adopt high-toughness alloy cast steel as raw material, processed through precision investment casting, multiple rounds of stress relief annealing heat treatment and CNC high-precision boring of roller mounting holes to achieve micron-level dimensional accuracy, the stable continuous operating temperature range covers -30℃ ~ +120℃, fully adapting to extreme climate environments in Russia’s cold mining areas, Middle Eastern high-temperature deserts and African plateau mining zones. The entire bogie body undergoes shot blasting surface treatment and anti-rust primer coating, effectively resisting oxidation corrosion under high-humidity coastal and tropical rainy weather, while the load-bearing arm adopts thickened wall casting design to eliminate permanent bending deformation risks under long-term full vehicle load cycles. Our OEM replacement 195-30-69221 bogie minors follow the complete original design drawings and production flow of genuine parts, adopt high-grade alloy cast steel raw materials from certified professional steel foundries, and implement the same annealing and precision machining processes as factory genuine bogies, balancing competitive procurement costs and long-term structural durability for medium and small mining fleets with limited maintenance budgets. All finished OEM 195-30-69221 bogie minors pass static load bearing inspection, repeated impact fatigue cycle test and roller hole matching tightness test before anti-rust packaging, and can be directly interchanged with original 195-30-69221 bogies without any modification during installation, perfectly compatible with all matched undercarriage auxiliary accessories including bogie housing sealing gaskets 17M-27-41490. The whole production process strictly controls the parallelism and roundness of all roller mounting holes to prevent axial deflection of track rollers during operation, reducing abnormal track friction loss even under 16-hour continuous heavy ore pushing work in high-temperature Middle Eastern open mines. 5.Performance Advantages First, the integrated thick-wall casting structure of Komatsu-parts-195-30-69221 realizes accurate positioning and stable load-bearing coordination with matched track roller assemblies, effectively solving the common failure of bogie bending and mounting hole expansion deformation that frequently occurs on low-quality aftermarket bogies. Long-term heavy mining load will deform inferior bogies, leading to uneven stress on track rollers, abnormal vibration during bulldozer walking, rapid wear of roller bearings and even track derailment accidents that stop all mine production; our genuine and OEM 195-30-69221 bogie minors maintain rigid structural stability for multi-year service cycles to completely eliminate this high-risk hidden mechanical fault. Second, high-toughness alloy cast steel raw material significantly improves impact resistance and long-term heavy load bearing capacity of the middle and rear undercarriage system. When D375 bulldozers push dense hard rock piles and travel on bumpy unprocessed mine roads, the 195-30-69221 bogie minor evenly distributes instantaneous ground impact loads to each group of track rollers, ensuring smooth and stable track walking without roller tilting or offset displacement, solving the trouble of frequent full undercarriage overhauls caused by low-rigidity cheap bogies under heavy mining working conditions. Third, multi-layer anti-corrosion surface treatment and stress relief annealing technology extend the service life of 195-30-69221 bogie minors by more than 70% compared with ordinary low-carbon cast bogies without reinforcement processing. Under all-day continuous operation in multi-dust, muddy and high-humidity construction environments, the surface protective coating of the bogie can resist rust pitting and casting fatigue cracking, reduce the frequency of full middle and rear track frame overhauls, and cut long-term mine equipment maintenance labor and spare part procurement costs for mining operators. 6.Suitable Working Condition This 195-30-69221 bogie minor is applicable to four mainstream heavy engineering operation scenarios: large open-pit mineral mining sites, mountain rock quarry crushing and stone stockyard leveling projects, highway and large-scale infrastructure earthmoving construction, and river channel dredging and silt removal engineering. It perfectly adapts to four typical global extreme working environments: ultra-cold frost-prone mining areas in Alaska and Russia with long-term subzero temperatures, arid high-temperature desert zones across the Middle East with strong sandstorms and intense sunlight, dry multi-dust plateau and savanna mining regions in Africa, and year-round humid muddy construction sites in Southeast Asia with frequent seasonal heavy rainfalls. No matter if D375 series bulldozers travel on hard rocky mine ground, soft muddy riverbed terrain or rough desert gravel road surfaces, the 195-30-69221 bogie minor can maintain stable rigid load-bearing performance without early structural deformation under continuous heavy vibration and impact walking cycles. 7.Source & Quality Assurance All genuine Komatsu 195-30-69221 bogie minors are sourced from official Komatsu original factory authorized supply channels, complete original factory export packaging and batch production certification documents are attached to each shipment. Our OEM 195-30-69221 bogie minors are manufactured by our cooperative professional heavy machinery chassis casting factory, every finished bogie passes three rounds of independent factory quality inspection before entering our domestic storage warehouse.
