Anti friction protection pad for shaft components -2243246 Caterpillar tile
In the engine rotation system, the tile (bearing shell) is the "core anti friction component" that fits the journal and forms a lubricating oil film. Its fitting accuracy and anti friction performance directly determine the journal life, rotational resistance, and engine running stability. 2243246 Caterpillar tiles are based on the core of "original factory grade journal adaptation" and "strong load wear resistance characteristics", becoming a reliable guarantee for Caterpillar equipment. Their value lies not only in "reducing friction", but also in their dual role of "protecting the journal and ensuring stable rotation".
As an original Caterpillar accessory, its thickness uniformity, contact arc surface, journal, and bearing seat are perfectly matched (specific compatible models can be consulted with customer service). The working surface processed by original factory grinding (roughness ≤ 0.2 μ m) can form a uniform oil film with the shaft neck (oil film thickness deviation ≤ 10%), avoiding "oil film fracture" (causing dry friction) or "local pressure overload" (such as when the excavator accelerates rapidly) caused by size deviation of general tiles, and reducing the risk of "fraying" and "tile burning" of the shaft neck from the source.
Material focus on heavy load adaptation: using copper lead alloy (containing tin element to enhance friction reduction), surface electroplated indium alloy (resistant to impact load, with a 40% increase in fatigue resistance compared to ordinary alloys), capable of withstanding instantaneous pressure on the shaft neck (over 30MPa); The back has undergone anti slip treatment (firmly attached to the bearing seat), which prevents displacement during high-frequency engine vibration and is suitable for continuous high load scenarios in mines and construction sites. Resistant to long-term immersion in engine oil (without corrosion or deformation), maintaining stable anti friction performance even in a 140 ℃ journal environment.
The implicit value is reflected in multiple aspects: a uniform oil film reduces rotational resistance by 25% (reducing power loss); The anti friction feature reduces the wear rate of the shaft neck by 60% (prolonging the life of shaft components); Stable fit reduces metal debris generated by friction (reduces oil pollution), and the incidence of engine noise is reduced by 50%. If the tile fails, there may be overheating of the shaft neck in the short term, and in the long term, it may cause a "shaft holding" fault, requiring a major overhaul of the entire machine.
