Slew Drives

Slew drives consists of ball bearings or roller bearings, worm gear and hydraulic/electric motor that can handle heavy rotational loads with very high torque/tilt torque. Together with our supplier IMO, we offer Bengtssons Maskin: Application Support, Storage against agreement and Installation of hydraulic motors, breaks, giver and gear motors.

 

Our slew drives from IMO are closed units, which means a high degree of reliability against external environmental influences and protects against both damage and lubricant loss, which gives longer durability and lower maintenance costs.

WD series

Slew drive series WD is intended for intermittent operation. The torque transmission takes place with a worm screw and worm wheel and is the product on the market that provides the highest torque transmission in relation to its size and weight. Slew drive series WD can be operated hydraulically and electrically.

New!

Slew Drive WD-E Alu Line

The new generation of slew drive is here! Our supplier IMO has developed and implemented a new product on the market: WD-E Alu Line. Engineered and designed based on the supplier's customer requirements.

Did you know that WD-E has 30 percent higher performance than the others? It is also 20 percent lighter in weight and has 300 percent longer gear life. 

 

WD-E Alu Line can be used in several different applications. 

 

Slew drive WD-L

Thanks to the high ratio in the worm, the WD-L series can transmit high torques despite its small dimensions from 3280 Nm to 446504 Nm.

WD-L can be rated for offshore or marine environment.

With its robust roller bearings, the WD-H offers significantly higher load capacity. The series' cylindrical rollers have a larger contact surface between the inner and outer bearing tracks, which leads to a significantly higher load capacity than other comparable models that use ball bearings.

With its high ratio, the WD-H can transmit torque from 11 Nm to 093 Nm.

SP series

Slew drive series SP (Spur Pinion) is intended for continuous operation. In the SP series, the torque transmission takes place with cylindrical gears and they are therefore not self-locking. In some applications, a brake may therefore be necessary.

New!

Slew Drive SP-H Open solution

IMO has now launched an extended standard program of their classic SP-H series. Raceway diameters 1055, 1155, 1255, 1355 and 1455 have been added.

 

Of course we will use our supplier Rossis gearmotorsto SP-H Open Solution.

For this product, all components, such as slewing rings, planetary gears and other motors are perfectly matched. 

 

The new sizes of SP-H can be used in several different application areas.

Slew drive SP-H

The pinion in the SP-H is supported using the planetary gear bearing.

The maximum torque is limited by the maximum radial force.

The pinion is supported by two radial bearings which are integrated into the motor mount. It uses a single row slewing ring ball bearing with hydraulic or electric drive. With hydraulic motor operation, the SP-I can be driven directly without an intermediate gearbox.

The highest torque is limited by the maximum input torque. Torque from 3 Nm to 500 Nm distributed among nine sizes.

Slew Drives/worm gear 

Our slew drives consists, as said, of ball bearings, worm gear and motor. These mechanical devices are used to transmit torque and rotation in various applications. Areas of use for slew drives spans a range of industries and applications. These devices are mainly used when there is a need to rotate or move a load in a circular or horizontal motion. Here are some examples of areas of use: 

  • Industrial applications: Slew drives are often used in industrial automation, material handling, machine tools, robotics and other process applications where there is a need to rotate large machine parts, manipulate heavy loads or change angular positions. 
  • Building and construction projects: Used in the building and construction industry slew drivesi applications such as tower cranes, excavators, lifting platforms and helipads. These devices enable precision and safety in lifting and rotating operations. 
  • Solar energy: Slew drives are important components in the solar industry and are used in solar trackers. Solar trackers follow the movement of the sun to maximize the amount of solar energy captured by the solar panels, and slew drives enables this movement by adjusting the angle and position of the panels. 

 

The functions by slew drives are designed to meet the requirements for robustness, durability and reliability. Key technical specifications may vary by manufacturer and application, but here are some common features and benefits: 

  • High load capacity: Slew drives are designed to handle heavy rotational loads and high torques. They can carry significant weight and withstand strong stresses during operation. 
  • Protection and sealing: Most slew drives are closed units, which gives a high degree of reliability against external environmental influences. This protects against dust, dirt, water and other contaminants that can affect the device's performance or lifespan. 
  • Low maintenance cost: The closed units also protect against lubricant loss and minimize the need for regular lubrication. This leads to longer durability and reduced maintenance costs in the long term. 
  • Flexibility and precision movement: Slew drives can deliver smooth and accurate rotation and adjust angular positions with high precision. This is particularly important in applications where precise control and positioning are required. 

 

One of the product series that we offer is the SP series. SP series of slew drives is designed to handle heavy rotational loads and high torques, offering a reliable and robust solution for a variety of applications. 

Another series to explore is the WD series. WD series of slew drives is specially developed to meet the requirements of various industries and applications. This series combines high load capacity with high precision and reliability. By using the WD series, you can get a powerful and versatile solution for your rotation and angle adjustment needs.
