Excavator Slewing Reducer Gearbox

Excavator Swing Reducer

Slewing Reducer & Swing Reduction Gearbox

It's important to note that slewing reducers, also known as swing reducers or swing gearboxes, are critical components that work in tandem with the slewing bearing to facilitate the controlled rotation of the excavator's superstructure.
We can provide OEM specification swing reducers for a wide range of excavator makes and models.NATIONAL Machinery provides the gearboxes gear parts for the excavators like Caterpillar, JCB, Hyundai, Hitachi, Komatsu, Volov,Kobelco, Doosan,Sumitomo, etc.

The Features of a Slewing Reducer for Excavators

High load carrying capacity - Slewing reducers are designed to handle the heavy loads and stresses encountered in excavator applications.

High stiffness - The rigid bearing design provides the necessary stiffness for stable and precise swing motion of the excavator.

Integrated gear teeth - One of the rings (inner or outer) incorporates gear teeth that interact with a swing drive to facilitate the 360-degree rotation of the excavator house.

Mounting holes - The inner and outer rings have mounting holes to directly attach the reducer to the excavator's house and undercarriage.

Rolling elements - Balls or rollers act as spacers inside the reducer to reduce friction and allow smooth, free rotation of the rings.

Lubricated environment - The interior of the reducer is heavily lubricated to minimize friction and wear between parts, which is crucial for reliable long-term operation.

Corrosion and wear resistance - Slewing reducers are made from durable materials that can withstand the harsh conditions encountered in excavator applications and reduce maintenance costs.

Compact design - The integrated bearing and gear mechanism allows for a compact and efficient design that fits within the excavator's structure.
