A grease composition is intended primarily for use in constant velocity joins (CV joints), especially ball joints and/or tripod joints, which are used in the drivelines of motor vehicles. The grease composition for use in constant velocity joints comprises at least one base oil, and least one thickener, at least one copper sulfide in an amount of approximately 0.01 wt-% up to approximately 1.5 wt-% of the grease composition, molybdenum disulfide and/or at least one phosphorus-free organic molybdenum complex in an amount of approximately 0.1 wt-% up to approximately 5.0 wt-% of the grease composition. Further, a constant velocity joint comprises the grease composition.

A constant velocity joint comprises an outer joint part with a longitudinal axis and first and second outer ball tracks. The outer joint part comprises an attachment side and an aperture side. An inner joint part has a longitudinal axis and first and second inner ball tracks. with a torque transmitting ball 14 in each pair of tracks, and a ball cage 15 with cage windows 18 in which the balls 14 are held. In each angular position of the constant velocity joint 11 an opening angle is enclosed between an outer tangent and an inner tangent at the ball. At least one of the first and second pairs of tracks is designed such that, within a small articulation angle range comprising at least the joint central plane, at at least an articulation angle, an opening angle amounts to zero, and within a greater articulation angle range, an aperture-side opening angle of a first pair of tracks widens in the opposite axial direction relative to the aperture-side opening angle of a second pair of tracks.

A rolling boot comprises a first fastening region for fastening the boot to a joint casing, a second fastening region for fastening the boot to a shaft, and a fold region between the first and the second fastening region with a first fold near to the first fastening region and a second fold near to the second fastening region. The boot further comprises, between the first fastening region and the first fold, a first transition region comprising a first flange neighboring the first fastening region with a bottom. A ratio between a first minimal diameter D1, defined by the bottom of the first flange of the first transition region, and a second maximal diameter D2, defined by the first fold, where both are viewed in a longitudinal section direction along the main axis, is between approximately 1:1.01 to approximately 1:1.25.
