Low friction rotary face seals
SLIDING SURFACE Ra 0.4 / STATIC SURFACES Ra 1.6
Among the frontal applications ATP has realised a low-friction profile that allows even significant axial recoveries. This is due to a geometry that generates little axial preload. The use of materials such as SINTEK D55 (very robust but with still elastic behaviour) is preferable in earth-moving applications where, in addition to general dirt, sludge or other hardened material must often be resisted.
RECOMMENDED LUBRICANT
OKS 1110 – Only suitable option with EPDM (NSF H1 certified)
OKS 480 – For seals and bearings (NSF H1 certified)
TECHNICAL NOTES
In cases of non-planarity exceeding 1mm, the regularly recommended solution is a low friction face seal. Owing to the increased axial flexibility, it can also be adapted to increased preload assembly. The use of lubricants is recommended on the sliding surfaces.
