drylin® linear plain bearing materials

Materials

igus® offers various materials for gliding elements and counter partners for the drylin® linear systems. Tests conducted over the years have shown that iglidur® J, J 200 and X are the ideal materials for most linear applications due to their positive properties in wear and friction.

Ideal material combinations

iglidur® J

The iglidur® J material achieved the best results among almost all shaft materials in our tests. Comparative laboratory tests show that iglidur® J is the most low-wear, low-friction polymer for linear applications.

Special properties of iglidur® J:

Maintenance-free dry operation

Low coefficients of friction with all materials

Excellent wear resistance

Very low humidity absorption

iglidur® J200

iglidur® J200 was designed and developed especially for linear applications together with hard-anodized aluminum. This combination achieves by far the best results in our laboratory tests.

Special properties of iglidur® J200:

Absolutely maintenance-free

Extremely high service life on hard-anodized aluminum

Low coefficients of friction with hard-anodized aluminum

Excellent wear resistance with anodized aluminum

iglidur® X

iglidur® X is characterized by high temperature resistance and compressive strength combined with extreme resistance to chemicals. iglidur® X achieves the best wear resistance on stainless steel and chrome-plated steel shafts.

Special properties of iglidur® X:

Absolutely maintenance-free

Temperature resistance -100°C to +250°C in continuous operation

Universal resistance to chemicals

Very low humidity absorption

iglidur® E7

iglidur® X has an excellent combination of high temperature resistance, high compressive strength and excellent resistance to chemicals. iglidur® reaches its best wear resistance on stainless steel and chromed steel shafts.

Special properties of iglidur® X:

completely maintenance-free

Temperature resistance from -50°C to +70°C in continuous operation

universal chemical resistance

very low moisture absorption
