CCTY Bearing Announces Expansion of Product Line Planetary Gear Bearings

(Lake Zurich, IL) After two years in development and extensive testing, CCTY Bearing is unveiling its newest bearing series, the RN and RNN full complement cylindrical roller bearings.

Planetary gears require immense power to move heavy equipment while operating within a compact design. This series from CCTY Bearing needs only a small amount of radial space and provides heavy load capacity.

Low friction, long life and high reliability are necessary bearing attributes for industrial gearboxes performing under dynamic and static loads that can reach their physical limits. The RN and RNN series meet performance requirements and feature:

  • Low noise and vibration
  • Precision grinding and super finish
  • Uniform contact stress from an optimized crown profile on raceways and rolling elements
  • RNN guide ring availability

Optional features include guide ring, flange and surface treatments to improve durability, life and speed. The cage-less design is ideally suited for planetary gears in:

  • Material handling
  • Construction equipment
  • Mining and heavy trucks
  • Wind energy
