JXL high-reliability bearings lead the wind energy technology revolution
[Guardian of clean energy transmission systems]
As a leader in wind power bearing technology, JXL provides global wind turbine manufacturers with full life cycle solutions that comply with GL certification and IEC 61400 standards. Our products have passed DNV GL type certification and are designed for 3MW+ large wind turbines and extreme conditions of offshore wind power, helping to increase the unit availability to 98.7% and achieve an ultra-long service life of 25 years.
▌Six major technical breakthroughs in the wind energy industry
Solving the core pain points of wind power operation and maintenance:
• Alternating load impact under variable wind speed of 10-25m/s
• Salt spray corrosion in offshore environment (C5-M level protection requirements)
• -30℃ low temperature cold start and 80℃ high temperature continuous operation
• 2000rpm high-speed micro-pitting protection for gearboxes
• The maintenance-free period of tower top components exceeds 5 years
• Transmission system efficiency loss <0.3%
▌Wind power bearing technology matrix
JXL four major innovative product systems:
▶ Main bearing long life series
Carburizing steel vacuum remelting technology: contact fatigue life L10> 400,000 hours
Adaptive lubrication system: intelligent adjustment of grease supply
Nano-composite coating: micro-pitting incidence rate reduced by 90%
▶ Gearbox reinforcement unit
Bimetallic composite raceway: anti-bonding ability increased by 150%
Planetary gear bearing: load-balancing error <2%
Oil mist sealing technology: leakage rate <0.1 ml/h
▶ Yaw pitch system components
Four-point contact ball bearing: 80% increase in overturning moment bearing capacity
Self-repairing grease: stable performance under extreme temperature difference (-40℃~120℃)
Lightning protection design: withstand 100kA transient current
▶ Intelligent monitoring bearing group
