An annular friction-clutch facing (30) for a multi-disk clutch (10) includes an inner edge (32) and an outer edge (34) defining a width (w) of the facing (30). The facing (30) further includes a first group of grooves (136, 236) formed on the facing (30) and having first cross-sectional area. Each groove of the first group (136, 236) has a first opening (38) at the outer edge (34) and a second opening (40) at the inner edge (32) remote from the first opening (38) and is adapted to direct lubricating agents across the width (w) over a substantial area of the facing (30). The facing (30) further includes a second group of grooves (42) formed on the facing (30) and having a second cross-sectional area smaller than the first cross-sectional area. The second group of grooves (42) includes first and second sets of grooves (44, 46, respectively). The grooves of the first set (44) are disposed in intersecting relationship with the grooves of the second set (46). The second group of grooves (42) is adapted to remove excess of the lubricating agents on the facing (30).
