The Ins & Outs of Slewing Rings

Posted by Richard Potesta on Wed, Mar 1, 2017 @ 08:03 AM

Slewing Ring Bearings

Slewing BearingsA slewing ring bearing is usually a circular device that supports the weight of rotating equipment and is used to turn devices of many sizes and types for industry, energy, transport, agriculture, radar and tracking devices, and even medical equipment. In different sizes and designs, slewing ring bearings turn heavy-duty cranes, offshore drilling equipment, and medical diagnostic devices.

Features of Slewing Ring Bearings

Slewing ring bearings are designed for large load-bearing capability and can manage a full range of heavy-duty mechanical equipment. These devices have the capacity for horizontal, vertical, or inclined operations of many varied applications. Each element may be custom designed to work independently or harmonize with existing equipment.

The variables of slewing ring bearings depend on the application, weight, and intended function of the equipment. Variable features may include:

  • Single, double, or triple row bearing design for light, heavy, and massive loads
  • Choices of mounting configurations
  • Options for raceway configurations that vary from 13 to 37-inches for the SlewPro Series 21 Series up to 12 or 180-inches for the SlewPro 100 Series.
  • Ball or cross roller designs
  • Sizes and location of bolt holes

SlewPro Slewing Rings are available in a variety of sizes and capabilities. Tailoring the models to differing uses and situations, SlewPro’s technicians can modify the design, each with a particular capacity and use, to match the specified requirements.

Slewing Ring Bearings Applications

SlewPro Slewing Ring Bearings perform the hardest tasks in a variety of situations. The slewing equipment turns the massive cranes on construction sites and other off-highway venues. These are present in most equipment that requires strength, turning ability, and precision.

Customized slewing devices operate:

  • drilling equipment
  • wind power devices
  • mobile robotics extensions
  • satellite equipment and mobile arms on spacecraft
  • space tracking equipment
  • solar tracking devices
  • packaging and bottling devices
  • medical packaging equipment
  • and much more

Quality Bearing Solutions

SlewPro produces the most efficient options for any application. The SlewPro engineers design the exacting solutions for any use using 3-dimension and FEA (Finite Element Analysis) technology to identify the ideal configuration for any project, large or small.

SlewPro Offerings

SlewPro offers a broad menu of slewing ring bearings configurations. These range from the SlewPro 21, 30, 40, 45, 50, and 100 Series. Each has different capabilities and functions.

  • SlewPro 21 Series works with an “L”-design to save weight. The Series offers 4-point contact and single-row ball slewing rings bearing.
  • SlewPro 30 Series has 4-point contact and a single-row slewing ring bearing for mid- to heavy operations.
  • SlewPro 40 Series offers low starting torque with double row ball slewing ring bearings for low starting torque applications.
  • SlewPro 45 Series provides maximum load capability in a small size.
  • SlewPro 50 Series offers a high dynamic capacity in a small size with single row cross roller slewing ring bearing.
  • SlewPro 100 Series, with triple roller slewing ring bearing,  delivers the highest level of capacity.
