CAMERA SUPPORT HEAD WITH DAMPING FLUID MIXTURE

摘要

"IMPROVEMENTS IN AND RELATING TO BEARINGS" The present invention relates to a bearing having at least two bearing surfaces provided with a clearance therebetween, the clearance being filled with a fluid mixture which provides a heavily damped viscous-drag on the bearing surfaces during slow relative movement of the surfaces and a substantially free-slipping movement of the surfaces upon a suddenly increased force being applied to the surfaces.
