Planetary Gear Bearings: RN & RNN Series


Planetary gears require immense power to move heavy equipment while operating within a compact design. Full complement cylindrical roller bearings need only a small amount of radial space and provide high load capacity.

RNN Bearing Double RowLow friction, long life and high reliability are necessary bearing attributes for industrial planetary gears performing under dynamic and static loads that can reach their physical limits. A cage-less design is ideally suited for gearboxes in material handling, construction equipment, mining and heavy trucks and wind turbines.

The RN and RNN series feature:
• Low noise and vibration
• Precision grinding and super finish
• Uniform contact stress from optimized crown profile on raceways and rolling elements
• RNN guide ring availability
• Surface treatment options to improve durability, life and speed
