Features
• Enhanced Skeleton Oil Seal Protection
Adopts high-quality nitrile rubber (NBR) or fluororubber (FKM) skeleton oil seals, achieving IP66 (SEA) / IP67 (WEA) / IP68 (PEA) protection ratings. It effectively prevents lubricating oil leakage and blocks dust, sand, water, and corrosive media, adapting to harsh working conditions such as mining and marine environments.
• High Torque & Load Capacity
The slewing bearing raceway is quenched to HRC58~62, and the worm gear is made of nickel-chromium alloy steel, enabling the drive to bear ultra-heavy axial/radial forces and overturning moments, with a maximum output torque of up to 3000N·m (PEA series).
• Stable Operation at High Speed
Optimized worm gear tooth profile design reduces meshing friction and heat generation, allowing the drive to maintain stable rotation at a speed of 1~3r/min without oil leakage or seal failure.
• Wide Temperature Adaptability
The skeleton oil seal is resistant to high and low temperatures, with the FKM type adapting to -40℃~+120℃, suitable for extreme temperature working conditions in metallurgy and polar regions.
• Easy Maintenance & Replacement
The skeleton oil seal adopts a modular design, which can be quickly replaced without disassembling the entire drive, reducing maintenance time and costs.
