Compact planetary gear

The 300M series drives are equipped with newly designed planet bearings, said to grant up to 50% more torque at high numbers of cycles. The series is fully interchangeable with the planetary gear 300 series and is suitable for integrated geared motors, IEC and NEMA electric and hydraulic motors.

Optionally, Bonfiglioli offers a compact self-cooling system for the entire planetary gear series, which increases the thermal performance by three times. The self-cooling system is robust and connects directly to the motor in a reliable way, allowing use of the full mechanical power without needing further external cooling circuits.

The 300M series, thanks to the enhancement of the planet bearings arrangements, ensures compactness, cost savings as well as up to 20 percent more lifetime and reliability. With the optional integrated self-cooling system, the new 300M series allows either a saving of at least one size or is an outstanding alternative to helical gearboxes. In addition, this integrated option is environmentally-friendly as no external cooling system is needed. \

Typical industries for the application are material handling, cranes and winches, mining, recycling, water and waste water, food and beverages, as well as numerous other industries where it comes down to a high torque density with an optimized space requirement.
