Description
What is a Slewing Drive?
A slewing drive (or slew drive for short) is a complete, ready to install system that consists of a ball or roller slewing ring (bearing), worm, and completely enclosed housing. It can be customized with hydraulic or electric planetary gearboxes with selectable IP grade based on different applications and customers’ demand.
It has the features of corrosion protection, high load, and high precision.
Worm gear slewing is widely applied in the relatively rotary parts of machinery and solar energy field such as solar tracking system, rotary chassis of aerial working machinery, truck crane, rock drill, drilling machine, grasping wood machine, code molding machine.
Key Features
1. An unlimited rotating angle and range
2. Provide the most efficient transmission of high power and torque possible
3. Completely enclosed and sealed housing withstands harsh environments and increases safety

Motor Selection
Optional Items: Brushed DC motors (12V/24V/48V) with or without hall sensors, brushless DC gear motors, AC Motor(220V/380V), Encoder.
Packaging and Shipping
Inner Packaging: anti-rust plastic film ; vacuum plastic bags.
Outer Packaging: hard carton; wooden case ; wood pallet.
Shipping Term: by express; by air; by land; by sea.
For samples, since the slew drive is with small dimension but heavy weight weight, it's not cost effective shipping by sea while the express shipping the cost-effective way, our logistitic staffs will asked TNT, DHL, UPS, FEDEX, to compare the express price in order to find the most cost effective way.
If in bulk order in the future, we recommend ship by sea.
Note:
Express: door to door, just need to pay the import tax if required by the custom.
By air or by sea: factory to destination airport/sea port, need pay destination fee charged by the airport(the destination fee is always charged by per B/L regardless of the package is big, small, heavy or light, in gerneral 200~400 USD per cargo) and import tax if required by the custom.
By train: sometimes the shipping price is the same as sea but taking less shipping time than sea, we will take this shipping way into consideration if the goods are in urgent need by our clients.
