[Data] Sliding characteristics of a sliding bearing for automobile engines with low friction properties.
Introducing methods for reducing friction in sliding bearings and the cross-sectional structure of developed materials!
This document reports on the sliding characteristics of automotive engine sliding bearings with low friction properties. It includes the concept of low friction bearings, bearing structure, wettability with lubricants, non-adhesiveness, as well as the starting friction coefficient from bearing performance tests and seizure tests. Engine bearings are required to respond to high surface pressure due to miniaturization and width reduction, low friction, and lead-free requirements, with an increasing demand for higher bearing performance. 【Contents】 ■ Overview ■ Introduction ■ Low Friction Bearings ■ Bearing Performance Tests ■ Conclusion *For more details, please download the PDF or feel free to contact us.

Company information
As a leading company in WPC processing, we achieve further reduction in friction and improvement in wear resistance and seizure resistance by combining it with other surface treatments such as DLC/PVD coating. WPC processing continuously shot-peens the metal surface with micro-sized media, generating residual compressive stress on the surface while simultaneously forming countless micro-dimples, significantly improving the fatigue strength and sliding characteristics of sliding parts. Fujii WPC Co., Ltd. boasts a wide range of processing achievements in industrial fields, from automotive parts to molds, cutting tools, and other tools, as a leading company in WPC processing. With composite processing using DLC coating, high-quality coatings have become possible for aluminum materials, which were previously difficult to coat. Additionally, by applying WPC as a pre-treatment for PVD coatings on molds, cutting tools, and other tools, we can further enhance the excellent performance of PVD. The lifespan of automotive parts, metal components, molds, cutting tools, and other tools can be increased several times! Further durability and friction reduction can be expected through composite processing combined with nitriding, carburizing, high-frequency hardening, and coating. We offer short delivery times, and orders can be placed from just one piece, including composite processing.
