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.

We produce seal joints and bearings for propeller shaft in pure copper, aluminium bronze, tin and lead bronze as well as brass. Pieces are delivered as-cast, rough or fully machined.

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.

Ceramic bearings Si3N4. Bearing cage PTFE. For most applications Si3N4 is the preferred material for ceramic bearings. Silicon nitride bearings are light, very hard and highly wear resistant. High and ultrahigh performance bearings are used in e.g. aerospace technology, metal production industries (high application temperatures), machine manufacturing, chemical industries (chemically aggresive substances), pharmaceutical and medical industries, semiconductor and biotechnology (clean room enviroments which may not be contaminated by lubricants). On request Special version with PEEK ball cage. Without ball cage.

Dimensional and running tolerances correspond to tolerance class PN acc. to DIN 620. The radial internal clearance corresponds to the clearance CN acc. to DIN 6204. These tolerance classes are standard and well suited for most applications.

Housing, stainless steel 1.4301. Bearing, stainless steel 1.4125. Seal, rubber NBR. Note 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.
