Abstract: A lift cylinder comprises a deflection roller device for an industrial truck. The deflection roller device includes a roller support, a lifting chain deflection roller having a roller axle and a roller body rotatably carried on the roller axle, and a first additional deflection roller arranged axially adjacent to the lifting chain deflection roller. The roller axle includes a cylindrical bearing portion and fastening ends projecting axially outwards on either side of the cylindrical bearing portion and fastened to the roller support. The first additional deflection roller is supported on a first additional-deflection roller support such that the axis of rotation of the first additional deflection roller is offset relative to the axis of rotation of the lifting chain deflection roller, and the axis of rotation of the first additional deflection roller extends through the roller body of the lifting chain deflection roller.

Abstract: The invention relates to a lift cylinder (17) comprising a deflection roller device (21) for an industrial truck (1), the deflection roller device (21) having a lifting chain deflection roller (36) having a roller axle (44) and a roller body (50) which is rotatable on the roller axle, a roller support (38) and at least one additional deflection roller (35) which is arranged laterally next to the lifting chain deflection roller (36), the roller axle (44) having a cylindrical bearing portion (48) which is received in the roller body (50) and fastening ends (46) which project axially outwards on either side thereof, which ends are fastened to the roller axle (38), wherein the additional deflection roller (35) is arranged on an additional-deflection roller support (54) such that the physical axis of rotation (60) of said additional deflection roller is offset relative to the physical axis of rotation (62) of the lifting chain deflection roller (36), and the additional deflection roller (35) overlaps in the radial
