Industries using Slewing Bearings

Slew bearings, also known as turntable bearings or slewing ring bearings, are large-diameter bearings, commonly used in heavy machinery, cranes, wind turbines and other applications requiring rotational support. Examples include

Slew rings from SKF group brand Kaydon are commonly used in a range of industries including oil & gas, renewable energy, robotics, mining, semiconductor and heavy equipment.

Slewing Drives

R.A. Rodriguez (UK) Limited are suppliers of slewing drives from TGB Group Technologies, who are a leading Spanish company established over 30 years ago to manufacture rotational innovations and technological movements.

A slewing drive is a gearbox designed to withstand radial or axial loads using high rotational torque. Within the drive is a slewing ring bearing which allows it to withstand heavy loads. Slewing drives can offer a versatile solution to those applications where strength and precision are essential.

The main features of the Slewing Drives are:

  • Possibility of 1 single axis or double axis
  • Transmission ratios from 1:40 – 1: 150
  • Custom modifications
  • Compact construction
  • Easy installation and maintenance
  • High precision with low reaction
  • Motorized connection flanges on both sides of helical gear
  • Long life performance
  • Sealed UV resistant
  • Protective dust layer

In addition to the standard slewing drives, we can also customise slewing drives according to your particular application, taking into account the following factors:

  • Dynamic and static axial
  • Gear ratios
  • Output
  • Precision
  • Radial dynamic
  • Tilting moment
  • Torque
  • Weight
Our range of slewing drives from TGB is vast, typically used in applications such as aerial lifts, airport luggage carousels, cable winders, cherry pickers, forklift trucks, hydraulic machinery, military equipment, satellite dishes, solar trackers and truck-mounted cranes.

Spur Gear Slewing Drives

A spur gear slewing drive is a new drive mechanism that incorporates turntable bearings and pinion gears to achieve precise movement and positioning.

This type of slew drive is used in various applications requiring controlled rotational motion with high efficiency and reliability, including machine tools, cranes and automation.

The main features of Spur Gear Slewing Drives include:

  • TGP-L, TGP-M and TGP-H series models
  • Easy installation
  • High transmission accuracy
  • High output speed
  • Easy maintenance and long service life
  • Customised options are available
TGB Spur Gear Slew Drive ball bearing ball for roller bearings, taper bearing or linear bearing rail, ideal if you need a press for bearings for linear motion bearing

Applications for Slewing Drives

Slew drives offer an array of possible solutions for applications where high torque creates precision positioning and rotational accuracy. The slewing drive is both powerful and reliable which make it highly suitable for use in many applications including:

  • Aerial lifts
  • Airport luggage carousels
  • Cable winders
  • Cherry pickers
  • Forklift trucks
  • Hydraulic machinery
  • Military equipment
  • Satellite dishes
  • Solar trackers
  • Truck-mounted cranes

Small Diameter MT Series Bearings

These slewing bearings provide optimal economy and capacity for a given envelope dimension. MT series heavy duty bearings are an economical replacement for kingpost designs and utilise the same four-point contact design concept as heavier duty slewing bearings, providing exceptional moment, thrust, and radial load capacities. These turntable bearings are suited for applications such as truck mounted cranes, hoists, and non-precision industrial tables and positioners.

  • 50mm – 300mm bore diameters
  • Replaces kingpost style design
  • Simple installation
SKF Kaydon's MT series slewing ring bearing and bearings is a skf bearing suitable for anyone looking for a linear bearing, a linear sliding rail or linear guide bearings. The MT series bearings ball bearings has a small diameter.

Reali-Slim TT® Turntable Bearings

To save weight, reduce product design envelope sizes and increase design flexibility, without compromising bearing performance and life , the Reali-Slim turntable bearings are ideal for more compact, more precise turntable designs.

  • Lightweight turntable bearings
  • Diameters from 1.5 inch to 6.0 inches
  • 25-inch cross section
  • Available with gear and ungeared
  • Stainless steel construction
  • Special designs & configurations available on request
Kaydon Reali Slim TT Turntable Slewing Ring bearing bearings belong to the S KF range of bearings & bearings, ring bearings that you will find in the skf bearing catalogue

Turntable Bearings / Slewing Rings

Slewing bearings are made up of an inner ring and an outer ring, one of these usually incorporates a gear. Both rings typically have an attachment hole, which allows for an optimised power transmission between adjacent machine components.
