Baoxing BX-300-WY Gear Grease Protects Intelligent Transmission Systems

In 2026, major exhibitions including AWE and CES keep driving industrial innovation. The rapid expansion of AI terminals, smart home appliances, vehicle electronics, humanoid robots and drones, together with accelerated edge-AI adoption, has made lightweight, low-noise plastic gears core components for precision transmission.


However, amid the trends of miniaturization, high-speed operation and wide temperature working conditions, improper grease selection has become a hidden leading cause of gear failure. Conventional lubricants easily lead to plastic swelling, deformation and brittle tooth breakage, resulting in excessive operating noise, transmission jamming, and even complete equipment breakdown, greatly shortening service life and damaging user experience.


Plastic gears made of Nylon, POM, PPS and other special polymers are highly sensitive to base oils and additives. Sulfur-chlorine extreme-pressure agents damage plastic molecular chains, while polar oils penetrate materials and cause swelling. Ordinary greases cannot meet the strict operational requirements of intelligent devices.

With 20 years of in-depth expertise in specialty lubrication, Baoxing has launched BX-300-WY High-Performance Precision Gear Noise-Reduction Grease to solve common plastic gear lubrication challenges. Featuring broad plastic compatibility and ultra-wide-temperature long-lasting lubrication, it effectively eliminates three major risks: material swelling, brittle cracking and abnormal noise. It fully adapts to precision transmission scenarios such as smart home appliances, automotive motors, AI terminals and medical equipment.


Formulated with synthetic base oil and inert additives, BX-300-WY has passed mainstream plastic compatibility tests to prevent corrosion and cracking fundamentally. It maintains stable performance across a wide temperature range of -40℃ to 150℃, perfectly coping with alternating hot and cold environments in vehicles and outdoor devices. Its high-adhesion oil film continuously reduces friction and wear, delivers outstanding noise reduction, and extends gear service life significantly. Heavy-metal-free and RoHS-compliant, it ensures safe and eco-friendly application.


Focused on customized industrial lubrication solutions for 20 years, Baoxing provides sample testing, professional material selection guidance and 24/7 technical support. We offer one-stop solutions for plastic gear compatibility and multi-condition adaptation, delivering reliable lubrication support for the high-quality development of the smart hardware industry.
