Axial bearings - Import export

Housing washer, shaft washer and rolling elements, bearing steel. Cage, steel. Note Axial ball bearings accept high axial loads from one direction but may not be loaded radially. The bearings are separable. This means the bearing parts can be fitted independently of each other. The main dimensions of the axial ball bearing conform to ISO 104 and DIN 711. Dimensional and running tolerances correspond to tolerance class PN acc. to DIN 620. These tolerance classes are standard and are well suited for most applications.

Steel housing. Nitrile rubber seal. Preloaded highaccuracy bearings with a 60° thrust angle. The bearings accept both radial and axial forces from both directions. Due to their preload, the angular contact ball bearings provide a high level of stiffness, excellent concentricity, precise tool positioning and repeatability. The integrated lowfriction seal effectively keeps dirt away from the bearing, thereby ensuring excellent operating safety and a long service life. The bearing friction coefficient Mrl is a reference value. The moment of inertia corresponds to that of the rotating inner ring. The limiting speeds are applicable after grease is applied. Technical data All bearings are supplied ready for mounting with lubricating grease type KE2P35 acc. to DIN 51825. Housing and shaft tolerances correspond to roundness tolerance class IT2 and perpendicularity tolerance class IT4.

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.

The axis height of the spindle bearings matches the fixed bearing unit 2407801. The floating bearing units consist of a housing with deep groove ball bearing, which adapts axially to the linear expansion of the spindle.
