Clip bearing, maximum compensation of tolerances, EGFM-T UW, igubal®

igubal® spherical bearings
 
The use of spherical bearings is usually associated with heavy bearing materials, difficult installation and high costs. Most of the time, maintenance is still necessary in 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 made from iglidur® UW, which is a material designed for underwater applications with higher temperatures up to +250°C. In addition, the plain bearings will run in chemicals which would act as a lubricant.

• Maintenance-free dry operation
• Easy assembly

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 reduced 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 30mm are required When rotation speeds higher than 0.5m/s are required

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

Assembly
Due to the tolerance compensation, no exactly toleranced housing is required. Please refer to the technical data for the respective maximum and minimum dimensions of the housing hole. In order to achieve the axial loads specified there, the bearing should be additionally secured axially.
