Lip seals - Import export

Race body steel. Wipers plastic/felt. Longitudinal sealing lips rubber. Rollers steel 1.3505. Note Roller carriage with lifetimelubrication roller bearings and wipers which lubricate the system when moving. By simply moving the centre cam roller, the roller carriage can be adjusted so that it is free of play or has the desired pretension in the rail. High travel speeds up to 7 m/s and extremely quiet (faster and quieter than systems that use recirculating balls). The wipers are fitted with an oilsoaked felt. This felt is in constant contact with the track to ensure perfect lubrication. The felts can be recharged using an oil pump through the lubrication points on the front. On request Roller carriages with 4 or 5 rollers.

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).

Inner ring, outer ring and rolling elements, bearing steel. Cage sheet steel. Labyrinth seal sheet steel. Lip seal NBR. Version 2Z = sealed both sides with noncontact labyrinth seals. 2RSR = sealed both sides with contact lip seals. Note Deep groove ball bearings accept high radial and axial loads. Axial loads are absorbed in both directions. The versions 2Z and 2RSR are lubricated for life with a high quality grease. The main dimensions of the deep groove ball bearings conform to DIN 6251. 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.
