Permissible p x v values for iglide® X6 plastic bushings with a 0.039 inches wall thickness, in dry operation against a steel shaft at 68°F, installed in a steel housing.
Deformation under load and temperature
With increasing temperatures, the compressive strength of iglide® X6 plastic bushings decreases. The graph on the left shows the elastic deformation of iglide® X6 with radial loads. At the recommended maximum surface pressure of 290 psi, the deformation is less than 2%.
Due to the high temperature resistance and good thermal conductivity, iglide® X6 is also suitable for high speed applications. At the given speeds, friction can cause a temperature increase to maximum permissible levels. In practice, this temperature is rarely reached due to varying application conditions.
Maximum recommended static surface pressure based on temperature (21,760 psi at +68°F)
The surrounding temperatures noticeably influence the wear performance of plastic bushings. The temperature resistance of iglide® X6 is among the highest in the iglide® range. In many tests it has shown a six times higher wear performance compared to the established high-temperature bearing iglide® T500. Another advantage to iglide® X6 is that axial fastening is only necessary at temperatures above 320°F.

Coefficient of friction for iglide® X6 as a result of the running speed; p = 109 psi
Similar to wear resistance, the coefficient of friction μ also changes with the load. The coefficient of friction of iglide® X6 declines with higher pressure and is practically constant for pressure above 4,350 psi. A higher speed also results in a lower coefficient of friction.
The best performance is achieved with the plain shaft materials free cutting steel and plain steel 1.0037. At higher loads, we recommend harder steel qualities. Non-hardened steel shafts can be worn be the bushing at pressure over 290 psi. The wear database shows that iglide® X6 is more suitable for rotating than for oscillating applications.

Coefficients of friction for iglide® X6 against steel (Shaft finish = 40 rms, 50 HRC):
|Coefficients of friction μ||0.08–0.15||0.09||0.04||0.04|
Coefficient of friction as a function of the pressure, v = 1.96 fpm
Coefficient of friction as a function of the shaft surface (1050 hard chromed)
Wear rotating with different shaft materials, p = 145 psi, v = 59 fpm
Wear with different shaft materials in rotational operation, as a function of the pressure
Wear for oscillating and rotating applications with shaft materials cf53 hardened and ground steel, as a function of the pressure.
The friction and wear are also dependent, to a large
degree, on the shaft material. Shafts that are too smooth
increase both the coefficient of friction and the wear of the
plastic bushings. The best shaft for iglide® X6 has a ground surface with an average roughness rms 16 - 32.

Effect of moisture absorption on iglide® X6 plastic bushings
|Specific volume resistance||< 105 Ωcm|
|Surface resistance||< 105 Ω|
iglide® X6plastic bushings have almost universal chemical resistance. They are only affected only by concentrated nitric acid and sulfuric acid. Due to its low moisture absorption, the material can be used in humid environments without problems. iglide® X6 is resistant to most typical detergents used in the food and packaging industries.
Plastic plastic bushings made from iglide® X6 are resistant to radiation up to an intensity of 2 x 105 Gy.y of 2 x 105 Gy
Partially resistant against UV rays.
In a vacuum environment, iglide® X6 plastic bushings can be used virtually without restrictions. Outgassing takes place to a very limited extent.
iglide® X6 plastic bushings are oversized before being pressfit. After proper installation into a recommended housing bore, the inner diameter adjusts to meet our specified tolerances. Please adhere to the catalog specifications for housing bore and recommended shaft sizes. This will help to ensure optimal performance of iglide® plastic bushings.
