The spindle (1) has inner and outer spindles (2, 3) between which an intermediate space is provided, where a sliding bush containing thermoplastic is provided in the space. The bush has a mixture containing polyetheretherketone, PTFE with volume portion in range of 7 percent to 13 percent, graphite with volume portion of 7 percent to 13 percent and carbon fibers with volume portion of 25 to 35 percent. A lubrication agent (11) is arranged in sliding contact between the bush and the outer and/or inner spindles. The lubrication agent has dynamic viscosity in range of 2000 to 4000 millipascal seconds at temperature of 25 degrees Celsius, in range of 600 to 1200 millipascal seconds at temperature of 80 degrees Celsius and in range of 150000 to 220000 millipascal seconds at temperature of minus 20 degrees Celsius.. |
