A sealing strip for a positive or negative pressure zone of a suction or blower roller of a machine for processing and/or producing web material, in particular a paper, cardboard or tissue machine. The sealing strip has a sealing face to be set against and in frictional contact with the inner side of a roller shell for sealing the positive or negative pressure zone during a rotational movement of the roller shell. The sealing strip has a lubricant channel in the form of a cutout from the sealing strip. The lubricant channel is arranged in front of the sealing face. The sealing strip is formed with a first material section at the sealing face and with a second material section at the front wall. The first and second materials are different in at least one physical property, such as modulus of elasticity, abrasion resistance, hardness, brittleness.
