Housing aluminium. Worm screw steel, worm wheel special brass. Version Housing anodised. Ball bearing with rubber sealing washer RS. Note Universally applicable and maintenancefree worm drive in one size with a centre distance of 20 mm and 7 different ratios. The housing is sealed to prevent grease leakage and keep dust out. These are left hand worm gears. The rotation direction on the shaft is arbitrary. smooth power transmission simple screw fastening quiet Note FR permissible radial force at FA=0 FA permissible axial force at FR=0

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.

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.

Housing steel. Cage plastic. Balls steel. Note The linear ball bearings correspond to series 3 of ISO 10285. With doublesided seal. The linear ball bearings have a plastic cage which results in quiet and outstanding running properties. With flange for direct mounting on the housing. Linear ball bearings with doublesided seal should be greased before installation. The specified load ratings apply with the use of hardened and ground shafts. Precision guide shafts 21595.
