In the field of heavy construction machinery, the reliability of every component directly affects the operating efficiency and safety of the equipment. Komatsu Bushing 195-71-74, a high-performance replacement bushing specifically designed for Komatsu construction machinery, plays a crucial role in reducing component friction, supporting moving parts, and extending the service life of core components.
I.What is I.Komatsu bushing 195-71-74?
Komatsu high-quality bushings 195-71-74 is a high-performance OEM replacement bushing specifically designed for Komatsu construction machinery. It belongs to the core components of sliding bearings and its core function is to reduce friction of moving parts, support moving parts, protect internal core components, and also has a sealing and protective function, which helps the equipment operate stably and extends its service life.
II. Features of Komatsu bushing 195-71-74?
a. Compatibility: Precisely matches Komatsu replacement D375 series (D375A, D375-5, D375-6) bulldozers and other heavy construction machinery, and can directly replace the original bushings without additional adjustments.
b. Material and process: Made of 40CR high-quality medium carbon alloy steel, precision turned, induction hardened, fine ground and surface rust-proofed, strictly following ISO 9001 and Komatsu original OEM standards to ensure stable quality.
c. Core performance: Surface hardness reaches HRC 58-62, with super wear resistance, impact resistance and sealing performance, equipped with uniform lubrication grooves, suitable for harsh working environments such as construction sites, and service life of no less than 8000 hours under normal working conditions.
d. Core value: It solves pain points such as excessive bushing wear, dimensional deviation, and component jamming, reduces equipment maintenance frequency and downtime costs, and is the preferred accessory for overseas Chinese buyers purchasing bushings for Komatsu construction machinery.
III. What are the advantages of Komatsu construction machinery bushings 195-71-74?
a. Highly adaptable: Precisely matches Komatsu D375 series (D375A, D375-5, D375-6) bulldozers and other heavy construction machinery. It is a direct replacement part from the original factory and can be installed without additional debugging, greatly improving maintenance efficiency.
b. Strict quality assurance: Made of high-quality 40CR medium carbon alloy steel, processed through multiple rigorous processes such as precision turning and induction hardening, strictly following ISO 9001 and Komatsu original OEM standards, with full-process quality inspection to eliminate unqualified products, ensuring quality consistent with the original manufacturer.
c. Outstanding durability: The surface hardness reaches HRC 58-62, with a deep effective hardened layer, providing superior wear resistance and impact resistance; equipped with uniform lubrication grooves and electrophoretic internal treatment, and an external anti-rust coating, it can isolate dust and moisture, making it suitable for harsh working environments such as construction sites. Under normal working conditions, its service life is no less than 8,000 hours, which is 30% longer than that of ordinary bushings.
d. Highly practical, reducing costs and increasing efficiency: It can effectively solve pain points such as excessive bushing wear, dimensional deviation, and component jamming, reduce equipment maintenance frequency and downtime, lower labor costs and overall operating costs, and help improve construction continuity.
e. Convenient and reliable procurement: Supports bulk wholesale and retail, with in-stock supply and fast delivery via international logistics such as DHL and FedEx. It also provides comprehensive after-sales support (quality warranty + technical support) to address concerns about procurement and use.
IV.What precautions should be taken when using Komatsu OEM bushings 195-71-74?
a. Installation Precautions: Before installation, clean the dust, oil, and rust from the installation area of the equipment to ensure that the mating surface is clean and free of debris; during installation, use a special tool to press it in smoothly and avoid violent impact to prevent the bushing from deforming, cracking, or damaging the equipment installation position, and ensure that it is installed in place (precisely mating with the matching pin without looseness).
b. Lubrication Precautions: After installation, add appropriate lubricating oil/grease in time to ensure that the lubrication groove is full of lubricating medium, and replenish it regularly thereafter (check every 100-200 hours depending on the working environment; the cycle can be shortened in harsh environments); do not start the equipment without lubrication or with insufficient lubrication to avoid dry friction between the bushing and the pin shaft, which will lead to rapid wear.
c. Working Condition Adaptation Precautions: This bushing is suitable for the normal operating conditions of heavy engineering machinery. It is prohibited to use it for operations that exceed the rated load of the equipment or involve high-frequency and strong impacts, so as to avoid damage to the bushing due to excessive pressure. At the same time, avoid the equipment from operating for a long time in dusty, watery, or corrosive environments. If this cannot be avoided, the maintenance frequency should be increased.
d. Daily maintenance and inspection precautions: Regularly check the wear, looseness and lubrication of the bushing. If severe wear, cracks, deformation, abnormal noise or jamming are found on the bushing surface, the machine must be stopped immediately and the bushing replaced to avoid damaging other core components of the equipment (such as pins, arm joints, etc.).
e. Replacement Precautions: When replacing, you must select Komatsu adapter bushings of the same model (195-71-74) and standard. Do not mix bushings of different specifications and materials. After replacement, you must re-check the installation accuracy and lubrication status. Only after the trial run is normal can it be put into formal operation.
f. Storage Precautions: Uninstalled bushings should be stored in a dry, ventilated, and non-corrosive environment. Avoid moisture, direct sunlight, or contact with corrosive substances to prevent the bushings from rusting or deforming, which could affect subsequent use.
