GGB's UNI, MINI and EXALIGN® self-aligning shaft bearing assemblies

GGB Bearing Technology EXALIGN™, MINI and UNI self-aligning bearing assemblies compensate for shaft misalignment up to +/- 5º, reducing edge-load, premature wear and power transfer deficiencies.

Highlights:

  • GGB self-aligning bearing assemblies work with a wide range of GGB plain bearings, simplify installation and increase application service life.
  • GGB self-aligning bearing housings adjust to +/- 5 degrees.
  • Bearing assemblies available in universal, flange or plummer/pillow block configurations.

Available in a range of configurations to meet most bearing assembly needs, these housings are compatible with a wide range of GGB plain bearings, simplifying installation and increasing service life.

The self-aligning sphericals are secured against distortion, and combined with different housings and GGB bearings, provide optimal design solutions for a wide range of applications.

The product line includes standard ranges:

  • MINI self-aligning housings are available in universal, flange or plummer block configurations, and are made of aluminum alloy with steel sphere inner material. They can accommodate bearing inner diameters of 8 to 15 mm.
  • UNI self-aligning housings are available in universal, flange or plummer block configurations, and are made of ductile cast iron with a steel inner sphere material. They can accommodate bearings with inner diameters of 10 -100 mm.
  • EXALIGN™ self-aligning housings are available in plummer block, or two- or four-bolt flange configurations, with both the housing and inner sphere material consisting of cast iron. They can accommodate bearings with inner diameters of 10 -100 mm.

These housings will most frequently be used with GGB’s line of metal-polymer and fiber reinforced composite bearings in applications including:

  • Wind energy plants
  • Car washes
  • Cleaning machines
  • Drum systems
  • Beveling equipment
  • Handling systems
  • Conveyor belts (pulleys)
  • Printing machines
  • Heating and ventilation equipment
  • Hoists
  • Cranes
  • Textile machinery
  • Special machine engineering
  • Bakery equipment
  • Marine equipment

Misalignment can cause shaft binding and edge loads that reduce bearing life and performance,” said Ümüt Elitok, Product Manager. “These high-stress contact points can cause premature wear on the bearing, negatively impacting the efficiency of related equipment and processes. GGB’s self-aligning bearing assemblies adapt to angular misalignment of a shaft, automatically micro-adjusting to movements. This reduces torque and friction, offering greater reliability, longer service life and lower cost of ownership. The addition of these self-aligning housings to the GGB family of products gives our customers a suite of optimized solutions for challenging operating conditions.”
