Lubricating greases - Import export

Elastomer NBR. Brace ring and tension spring steel. Rotary shaft lip seals are readytoinstall seals for sealing rotating shafts. They are made from an elastomer outer sleeve and an internal bracing shim. The tension spring ensures increased pressure of the lip against the shaft and supports static sealing. Form A DIN 3760 (ISO 6194/1) version, smooth OD. Form AS DIN 3760 (ISO 6194/0) version, smooth OD with extra dust lip to protect from external dirt. The material NBR has a high wear resistance and is resistant to motor fuels, oil, hydraulic oil and lubricating grease. Operating limits Circumferential speed (m/s) ≤12 Pressure (MPa/bar) ≤0.05/0.5 (rotary shaft lip seals are generally meant for unpressurised operation).

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.

Bearing block and carriage aluminium alloy. Guide column and threaded spindle stainless steel. Plain bearing for guide columns and spindle nut highquality special plastic. Claw coupling aluminium with polyurethane coupling spider. Version Aluminium alloy anodised. Stainless steel hardened and ground. Threaded spindle with ball bearing. Note for ordering The unit is supplied with the position of cable outlet or control unit as shown in the drawing. Note Positioning stages for motorised adjustment and positioning tasks. The plain bearings and spindle nuts are suitable for dry running, however lubrication with a grease for plastic plain bearings is recommended. The suitable programming software and interface cable for the stepper motor with positioning control are available as accessories (2500015).
