Smooth Shipment of Komatsu Bulldozer Shock Absorbing Rubber Pads (Part No.198-12-41180) to Overseas Distributor
Word count: ~700 Date: July 3, 2026
Our company, a professional manufacturer and exporter of construction machinery replacement parts, has completed container loading and formal shipment of a bulk order of shock absorbing rubber pads, part number 198-12-41180, specially engineered for Komatsu D275 and D375 bulldozers. This batch of composite rubber shock pads is bound for our long-term cooperative distributor in Southeast Asia, who supplies maintenance spare parts for local mining, road construction and earthmoving projects. The full set of export customs documents, including commercial invoice, packing list, factory inspection certificate and certificate of origin, has been fully sorted and submitted for clearance, guaranteeing seamless cross-border logistics and on-time arrival at the destination port.
As a core vibration-isolating component installed on bulldozer cab bases and vehicle frames, this spare part is known interchangeably as rubber sheet, rubber pad or shock absorbing pad across the global machinery aftermarket. It gets its universal naming for two straightforward reasons: first, elastic vulcanized rubber serves as the functional core to buffer violent vibration generated by engines and walking assemblies; second, its flat thin-plate appearance distinguishes it from thick block-style rubber mounts. End-users rely on this composite pad to reduce cab shaking during heavy-duty operations and protect welding seams of bulldozer frames from fatigue fracture caused by long-term continuous vibration.
All shipped rubber pads adopt original-equipment-grade rubber-steel composite structure with strict raw material control. The elastic layer is formulated with high-quality natural rubber (NR), controlled at 60~65 Shore A hardness via complete vulcanization systems including zinc oxide, stearic acid and sulfur curing agents. Carbon black is added as reinforcing filler to boost tensile strength, tear resistance and wear performance, while anti-aging agents and softening oil are blended to resist erosion from engine oil, construction dust and outdoor ultraviolet exposure, effectively extending service life under harsh mine and construction working conditions. Multiple layers of degreased and phosphated cold-rolled steel plates are embedded as reinforcing interlayers. After high-temperature vulcanization at 145–155℃ under 12–18MPa pressure for 25 to 40 minutes, rubber and steel plates are integrated permanently without delamination, with steel layers bearing heavy loads and restricting excessive rubber deformation to avoid permanent collapse under sustained compression.
Every piece goes through standardized compression molding composite vulcanization workflows before delivery. The full production chain covers internal mixing of rubber compounds, metal plate surface passivation, layered stacking and mold filling, high-pressure integrated molding, flash trimming, bolt hole stamping and strict finished-product testing. Our QC team conducts batch inspection focusing on rubber hardness, rubber-steel peel strength, compression set and anti-tear property; only fully qualified goods enter warehouse and packaging procedures. For ocean transportation, each rubber pad is wrapped with dustproof waterproof plastic film and sorted into export cartons with clear marking of part number, applicable bulldozer models and quantity, while pallets are reinforced with binding belts to prevent collision and displacement during long sea transit.
This shipment once again proves overseas clients' recognition of our precise OEM matching, stable material quality and efficient delivery cycle. Our one-stop export service covers technical consultation, customized production, quality monitoring, standardized export packaging and full documentation support. Moving forward, we will keep optimizing manufacturing techniques for construction machinery rubber shock parts, expand our spare parts product lineup for Komatsu heavy bulldozers, and maintain reliable supply for global machinery distributors, delivering durable, cost-effective replacement components to cut clients' equipment maintenance downtime and operational costs
