1. A system for use in a scroll compressor, the system comprising:
a crankshaft with a first end portion, wherein the crankshaft defines an axis of rotation;
a slider block having a recess, wherein the first end portion of the crankshaft and the recess in the slider block are configured for connecting the slider block to the first end portion;
wherein the first end portion of the crankshaft comprises a first flat contact surface portion and the recess of the slider block comprises a second flat contact surface portion, wherein the first and second contact surface portions face each other when the first end portion of the crankshaft is connected to the slider block,
wherein at least one of the flat contact surface portions comprises a slit beneath the at least one flat contact surface portion,
wherein the slit is configured to reduce a stiffness of the at least one of the flat contact surface portions,
wherein the slit is oriented perpendicular to the axis of rotation defined by the crankshaft, and
wherein the other flat contact surface portion is curved in a direction parallel to the axis of rotation defined by the crankshaft.
