摘要：A method for the production of an internal slide surface on a guide sleeve ofplastic material for a length-adjustable chair column consists in that the internal surfaceof the guide sleeve is provided with surfaces, which are undersize in proportion to a to-be-guided housing of a gas spring. Recesses are located between the individual surfacesand are oversize in proportion to the housing of the gas spring to be guided. Partialcylinder surfaces are broached in the surfaces between the recesses by broaching and incommon they represent a slide surface. These measures ensure impeccable broachingwith high surface quality and dimensional precision of the slide surface. Moreover, theremaining recesses, which may have the form of grooves of arbitrary cross- section, canbe used as storage chambers for a lubricant.
