Overview

Randomized trial improves friction reduction and wear resistance in cylindrical roller bearings, suggesting enhanced mechanical efficiency.

Key Points

The aim is to enhance the tribological performance of cylindrical roller bearings using a hybrid nano-lubricant for improved durability and efficiency.
Developed and tested WS2-CuO hybrid nano-lubricant in biodegradable polyalphaolefin.
Combined laser-textured bearing surfaces with measured lubricant distribution under high-speed (15,000 rpm) and high-load (10 kN) conditions.
Employed Particle Swarm Optimization (PSO) to fine-tune nanoparticle concentration, lubricant flow rate, and surface texture parameters.
Achieved a coefficient of friction of 0.068, a 42% reduction compared to base oil (0.120).
Wear volume decreased by 48%, with friction rotation reduced by 35%.
Demonstrated a 2.5× increase in load-carrying capacity and an EHD film thickness of 1.22 μm.
