FWA Series FWA21-2 Slewing Drive Reducer Slewing Drive For Excavator Accessories
Swing Drive for excavator attachments
You should look at different models when buying a swing drive for your excavator. Wd-h, wd-l, and PE series have different price ranges. These drives can be installed in a tiny space. The PE series is more expensive than others, but it has many functions. 700tk series is specially designed for excavators below 150 tons. These units are equipped with integrated axial piston hydraulic motors.
WD-H
WD-h rotary drive series is a kind of heavy-duty rotary drive. It adopts a cross roller bearing design, with a compact design and high load capacity. Its compact design makes it an ideal choice for compact excavators. It can be equipped with one or two motors. Wd-h series is smaller in diameter and lighter in weight than similar rotary drive devices.
WD-L
Wd-l excavator accessory slewing drive is the perfect solution for high-precision applications. Its design allows accurate control up to 0.15 degrees. It can be used for horizontal and vertical output shafts with the sealing points down and up. It has high gear efficiency and is designed to allow reversing without brakes.
PE Series
Swing drive is the essential equipment of the excavator, which helps the machine move forward. They come in different models and designs. They can be used in various machines, including wind turbines, excavation derricks, fog trucks, and medical equipment. Different types of rotary drives have different functions. Users should choose the type that best suits their application requirements and environment.
WD-X
Wd-x rotary drive for excavator accessories is a hydraulic rotary drive with adjustable back pressure. This type of actuator can operate at a back pressure between 0.3 MPa and 10 MPa. You should use mineral-based hydraulic oil with anti foam and anti-oxidation properties. The oil must be kept between - 20 and 80 ºC. In addition, it should have low pour points, high viscosity, and high accuracy.
WD-S
WD rotary drive of excavator is a high-performance hydraulic accessory with many advantages. It is designed with a fail-safe function and advanced structural analysis to reduce maintenance costs. Its main parts are wear-resistant steel, and the parts bearing excessive stress are high tensile strength plates. The slewing drive has a plurality of mounting holes, which can be installed on the excavator chassis, houses, and other structures. WD swing drive is compatible with many leading brands and models of excavators to maximize power output.

Application
hzpt slewing drive is a gearbox designed to handle radial or axial loads using high rotational torque. In addition, the slewing ring bearing, at the heart of the drive, enables it to withstand high overhung or moment loads. A descendant of the "worm" screw, slewing drives are present in construction machinery, manufacturing, equipment, and many other applications that require strength and precision.
The physics of the slew drive makes it a versatile solution for many applications. In operation, the slew drive's axial movement, or motion around its axis, interacts to create radial torque. The action occurs by meshing the grooves of the horizontal screw with the teeth of a perpendicular gear. While turning, the worm gear's axial movement transfers magnified torque force to the radial gear. The number of threads on the horizontal screw and the number of gears that interact will determine the speed ratio of the setup.
Slewing drives are available in many configurations depending on the task at hand. These may be single-axis or dual-axis turning in unison.
