Guide bushes bronze maintenance-free - Plain bearing

Selflubricating. Hardness 190220 HB. Note The guide bushes are radially and axially applicable. The bearing elements are maintenancefree and wearresistant. The graphite inserts provide lifelong lubrication. Preferably for travel speeds < 0.5 m/s. (Additional lubrication is recommended for extreme loading with a higher travel speeds). Temperature range Temporary temperature peaks up to ca. 200°C. Tolerances The bore for the bearings should correspond to ISO tolerance H7. The tolerance h6 to h7 is recommended for the shaft.
