Particle Size vs Bushing Lifespan: Practical Thresholds","og_description":"Tungsten carbide bushings are widely used in pumps, compressors, and slurry systems because they resist wear better than most materials. But even tungsten carbide has limits when abrasive particles are present in the fluid. The size, hardness, and concentration of these particles have a major impact on bushing lifespan. This article explains how abrasive particle size affects wear, what thresholds decision-makers should watch, and how to reduce damage in real applications. Why Abrasive Particle Size Matters for Tungsten Carbide Bushings Abrasive wear happens when hard particles slide between the shaft and the bushing surface. Tungsten carbide is extremely hard, but once particles become large enough, they act like cutting tools.
