Rubber steel seals - Import export

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.

Housing, grey cast iron. Bearing, ballbearing steel 100Cr6. Seal, rubber NBR. Pillow block bearings consist of a sealed singlerow ball bearing with a spherical outer ring which is mounted in a housing. Because of the spherical outer surface of the bearing, shaft misalignment can be compensated for. The bearings are manufactured with a plus tolerance. This results in transition or press fits when using shafts with htolerances. The shaft is secured by grub screws on the inner ring. In normal applications, pillow block bearings are maintenancefree due to the lifetime lubrication. In difficult environmental conditions relubrication can be carried out over the grease nipple. All housing dimensions are nominal dimensions for which the usual casting tolerances must be taken into consideration.

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.
