Avoid reduced press fit due to anti-corrosion agent

iglidur® bearings were tested in combination with various corrosion protection agents

Initial situation

If a bearing position is to operate 100 % lubrication-free, it may be advisable to treat the bearing seat with an anti-corrosion agent. These agents may reduce the seizure of the bearing.

Plain bearing with reduced press fit moves out of the bearing point

Plain bearing with reduced interference fit moves out of bearing position

Test: displacement force with different anti-corrosion agents

The test shows that almost all anti-corrosion agents reduce displacement force. Only TectylTM 300G Clear E enhances press fit.

Result: TectylTM 300G Clear E under the influence of motion and force

Even under the influence of force and movement, TectylTM 300G Clear E can achieve a higher tight fit of the bearing. In the test, it is almost twice as high as with the plain bearing without anti-corrosion agent.
