Intelligent factory AGV automated guided vehicles operate with frequent start-stop, variable load and long-time continuous shuttle operation inside workshop, warehouse and logistics distribution center. Silicon nitride balls are gradually applied in AGV wheel bearings and guide rail rolling bearings to solve rapid wear, rust and frequent maintenance problems of traditional steel bearing schemes, improving intelligent logistics equipment operating stability.
AGV vehicles bear dynamic impact load during acceleration, deceleration, steering and obstacle crossing. Ordinary steel balls generate surface indentation plastic deformation after long-term repeated impact, leading to wheel jitter, walking deviation and positioning inaccuracy. High-hardness silicon nitride balls resist indentation deformation effectively, maintaining long-term dimensional precision of wheel bearings and ensuring AGV walking route accuracy without regular position calibration adjustment.
Workshop environment exists humid air, cleaning water splashing and trace chemical volatile gas; steel bearings easily rust and seize after long-term operation, increasing AGV failure rate and affecting automatic production scheduling continuity. Silicon nitride balls own excellent anti-corrosion property, avoiding rust failure under damp industrial environment and extending bearing service cycle greatly for unattended automatic logistics vehicles.
Lightweight characteristic reduces starting energy consumption of AGV driving motor. Lower rotary inertia enables quicker response during vehicle startup and steering adjustment, improving operation flexibility and handling efficiency of intelligent handling robots. For fleet-scale AGV group running 24 hours a day, cumulative power saving brings obvious operating cost reduction for intelligent warehouse enterprises.
Dust resistance and wear resistance adapt to workshop floating powder and particle pollution. Processing debris, dust and plastic particles floating inside factory easily enter bearing interior and accelerate steel ball abrasion; high wear-resistant silicon nitride balls slow abrasive wear progress, reducing bearing clearance expansion speed and lowering regular maintenance frequency of lubrication replenishment and bearing replacement.
With rapid popularization of smart factory and unmanned logistics system construction, customized-size silicon nitride balls matched for AGV bearing assembly will gain larger market share, becoming important wear-resistant upgrading material for new generation intelligent handling equipment design.
