Product description
igubal® spherical bearings
 
The use of spherical bearings is usually associated with high weight bearing materials, difficult installation, and high costs. Most of the time, maintenance is still necessary over the long-term, and the bearings are only corrosion-resistant in special designs. Often roller bearings or plain bearings malfunction prematurely due to high edge loads, or because they need to be elaborately readjusted, reamed, or refitted in order to compensate for alignment errors. igubal® spherical bearings put an end to all of these disadvantages and open up many new possibilities for your engineering design: they are easy to handle, cost-effective, lightweight and robust.
 
The housing is made from igumid G, an extremely impact-resistant, long-fibre-reinforced polymer. Suitable for temperatures from -30 °C to +80 °C in long-term use.
 
Here, the spherical ball is manufactured from iglidur® R, which is a low-cost material with low coefficients of friction and good wear resistance at low to medium loads.
  • Maintenance-free dry operation
  • Mechanical joining link between two components
  • Compensation of misalignment errors
  • Corrosion-resistant

Typical application areas
  • Food industry
  • Railway technology
  • Automotive industry
  • Plant construction

When to use it?
  • For high axial and radial loads
  • When easy installation is required
  • In case of cramped installation space
  • If chemical resistance is required
  • If a cost-effective option is required
  • If you need dirt-resistant bearings
  • To adjust misalignments
When not to use it?
  • If temperatures are higher than +80 °C
  • If diameters above 12 mm are required
  • If rotation speeds higher than 0.5 m/s are required

Tolerances
Maintenance-free igubal® spherical bearings have a tolerance in the inner diameter of E10. The shaft tolerance should be between h6 and h9. The bearing clearance allows for expansion of the bearings due to increasing temperatures. Check the inner diameter
 

Assembly
igubal® spherical bearings are press-fitted into a recommended H7 housing bore and axially secured. Exact alignment of the bearing housing is not necessary since the spherical bearing automatically compensates for alignment errors.
