Plain bearing for rotary stages

Material Ballbearing steel 100Cr6. Seal, rubber NBR. Version Sealed on both sides with a spherical outer ring. Can be relubricated. Note The internal construction of the insert bearings corresponds to that of standard Series 6200 and 6300 radial ball bearing. However, they have wider inner rings for easier fastening on shafts. The inner rings are manufactured with a plus tolerance. This results in transition or press fits when using shafts with htolerances. The shaft is secured by 2 grub screws positioned 120° apart on the inner ring. The insert bearings are ready to install and are permanently lubricated with a suitable ball bearing grease. In normal applications, relubrication is not necessary.

Carriage body zinc. Plastic bearing material iglidur® J. Rails anodised aluminium. Version Body chromed. Guide rail natural colour anodised. Note Miniature slide guides are maintenancefree and corrosion resistant. Very high speeds and accelerations are possible due to the low weight. Applicable temperature max. 80 °C. Miniature slide guides are insensitive to dust and are ideal for dry running. ** length L2 = 30 mm and * L = 1000 mm included L2 and L only available in full 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.
