Axial bearings - Import export

Thrust bearing / Spherical axial bearings from igus d1 [mm]: Mechanical properties The self-aligning spherical igubal ® thrust bearings are very easy-to-mount units, which help to compensate for errors and prevent misalignments. The thrust bearing housing pad is made of the impact-resistant, stiff, thermoplastic composite material igumid G. The standard thrust bearing washer is made of iglidur® W300. This combination provides particularly good gliding and wear properties in relative movements. Loads The load carrying capacity of the spherical igubal® thrust bearing is very high in normal ambient temperature. In particular cases the load carrying capacity of the axial bearings should be checked in a practical trial with high constant loads and at higher temperatures. Coefficients of surface friction and speeds Taking the radial loads into account, maximum surface speeds up to 0.5 m/s rotating can be attained. Installation The axial bearing pad is mounted flush and secured. The spherical washer glides loosely in the pad and is held by the shouldered shaft mounted on it. Delivery program As standard, the spherical igubal® axial bearings are supplied in sizes of 5 to 20 mm. For other dimensions, please contact us. Special features Simple assembly Compensation of misalignments Compensation of edge loads Very good gliding and wear properties, low installation space When to use it? When you want to save weight When freedom from corrosion is required When a bearing with good friction coefficients is sought When not to use? When very heavy loads act When constant temperatures of more than +80℃ occur When high rotary speeds must be implemented. Thrust bearing / Spherical axial bearings from igus d1 [mm]:

iglidur® JATM, metric d1 [mm]: iglidur® JATM/VATM consists of a hard-anodized ring and a bearing ring made of iglidur® J (JATM) and iglidur® V400 (VATM). These glide pairings fetch low coefficients of friction and high wear resistance - without lubrication. Special features Maintenance-free plain bearing system For high service performances High stiffening Simple installation Material: iglidur® J High temperature options VATM, iglidur® V400 More dimensions and supplies on request When to use it? When an axial bearing system with defined gliding partners is desired When extremely high wear resistance is required When a very low coefficient of friction is desired When not to use it? When an additional angle compensation is required igubal® axial bearing When little mounting space is available iglidur® J When only sporadic movements are present iglidur® G Y = wear [μm/km] Figure 36.1: The diagram shows the influence of load (p in MPa) and speed (v in m/s) on the wear of the axial bearing. Y= Coefficient of friction Figure 36.2: In the test with different speeds (v) and loads (p) the coefficients of friction of the bearing systems were determined (v in m/s, p in MPa). iglidur® JATM, metric d1 [mm]:

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.

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.
