195-30-62141 cap Komatsu D375 bulldozer spare parts

The Komatsu D375 cap 195-30-62141 is a “protective sealing core” for chassis component connections. It fits tightly against the pins and bolt ends, effectively isolating oil, mud, water, and dust from intrusion, preventing component corrosion and wear. At the same time, it plays a role in preventing loosening and locking the stability of the connection. It is specially designed for the chassis pin and bolt connection parts of Komatsu D375A-2/A-5/A-6/A-8 models, which can avoid component failure caused by cap damage or loosening, ensure normal equipment operation, and improve construction efficiency.
This product strictly adheres to Komatsu’s original standards and references the D375 series (474kW power, 72-ton operating weight) chassis component specifications. It utilizes high-quality 45# steel with a corrosion-resistant galvanized coating, offering advantages such as wear resistance, corrosion resistance, tight sealing, and easy installation. Precision machining and polishing ensure accurate dimensions and a high degree of fit, perfectly matching the end dimensions of original components for direct installation. This effectively reduces downtime losses, extends the lifespan of chassis connection components, and lowers maintenance costs. Widely used in mining, earthmoving, and infrastructure industries, it is a core consumable for chassis component maintenance.

Core technical parameters:

– Product Model: Komatsu D375 Cap
-Part number 195-30-62141
– Product Type: Protective caps, core components for protection, sealing, and preventing loosening of chassis pins and bolt connections.
– Core materials: The main body is made of 45# high-quality steel; the surface is coated with hot-dip galvanized corrosion-resistant coating; the sealing parts use nitrile rubber sealing rings.
– Material characteristics: 45# steel has a tensile strength ≥600MPa, yield strength ≥355MPa, and hardness ≥170HBS; the galvanized coating has strong corrosion resistance and is not easy to peel off or rust; the nitrile rubber sealing ring is resistant to -30℃~+100℃, has stable sealing performance, and can effectively prevent impurities from entering.
