|1) Without additional load; no gliding movement; relaxation not excluded.|
For iglide® B bearings with 1 mm wall thickness in dry operation against a steel shaft, at 20° C, installed in a steel housing.
Vibration dampening and the separation of impact sound were the focus in the development of iglide® B.
The operating temperature of the iglide® B bearings is limited to 100° C. From 50° C onward, the very soft bearing should be mechanically fastened, so that the danger of bushings creeping out of the bores is avoided. The wear resistance too declines disproportionately from 70° C.

|Upper, long-term||+ 100 °C|
|Upper, short-term||+ 130 °C|
The iglide® B bearings assume a center position in wear resistance. As far as the bearing load is not too high, the attained coefficients of wear are pretty good. An increase in load results in a disproportionate increase in abrasion.

iglide® B bearings are not very resistant to chemicals For chemical resistance, there are other iglide® materials available with better properties.
iglide® B bearings are radiation resistant up to a radioactive intensity of 3 x 10² Gy.
iglide® B bearings are not resistant to the influence of UV rays.
The use in vacuum is possible only conditionally. Only dry bearings made of iglide® B should be tested in vacuum.
Bearings made of iglide® B are electrically insulating.
The iglide® B bearings are manufactured according to order specifications.
