igubal - Technical data

Both the bearing spherical cap made of iglidur® W300 and the housing made of igumid® G are resistant to weak alkalis, weak acids, fuels and all types of lubricants. The moisture absorption of igubal® is around 1.3 % by weight in a normal climate. The saturation limit in water is 6.5%. This must be taken into account with corresponding environmental influences. The HT version can be used for higher chemical resistance.

Chemical resistance of igubal® bearing elements

The load capacity of the maintenance-free igubal® bearing elements is very high at normal ambient temperatures. igubal® bearing elements absorb high forces and weigh only a fifth of conventional metal bearing housings. The excellent damping properties are due to the fact that, unlike steel, the plastic material of the two-part bearing can absorb vibrations.

However, plastic-specific specifications such as temperature dependency and creep behaviour must be taken into account during use. For this reason, the load-bearing capacity of the rod end should be checked on a case-by-case basis in a practical test, particularly in the case of high continuous loads, low load speeds and higher temperatures.

Sliding friction coefficients and speeds

An important advantage of the maintenance-free igubal® bearing elements is that fast rotational movements of the bearing shaft take place directly in the bearing spherical cap made of iglidur® W300. The advantage of this plastic/steel plain bearing is that high speeds are also possible in dry operation. Taking the radial load into account, maximum sliding speeds of up to 0.5 m/s are possible in rotation.

The angular movements of the spherical bearing, on the other hand, take place on the spherical outer diameter of the bearing calotte.

The maintenance-free igubal® bearing elements also allow linear movements of the shaft without further ado.
