iglide® plastic bushings - temperature

Application Temperatures

The minimum application temperature is the temperature below which the material becomes so rigid and hard that it is too brittle for standard applications. The maximum continuous application temperature is the temperature which the material can endure without its properties changing considerably.

The maximum short-term application temperature is the temperature above which the material becomes so soft, that it can only withstand low external loads. 'Short-term' is defined as a time period of a few minutes. If the plastic bushings are moved axially or axial forces occur, there is more opportunity for the bushing to lose its pressfit. In these cases, axial securing of the bushing is required in addition.

Column 3 shows the maximum ambient temperatures to which the plastic bushings can be exposed in the a short-term. If these temperatures are reached, the bushings may not be additionally loaded. In fact, a relaxation of the bushings can occur at these temperatures, even without an additional load. For this reason, it's necessary to ensure that the bushing can not slide out of the bore. This is achieved by changing the bore construction or by additionally securing the bushing.

Column 4 shows the maximum ambient temperature the plastic bushings can tolerate for a short period of time. If these temperatures are acting on the bushings, they should not be additionally stressed. At these temperatures, relaxation of the bushings inside the housing can occur, even without any additional load. Attention should be given to ensuring the plastic bushings are prevented from slipping out of the bore either by changing the bore construction or by additionally securing the bushing.
