Bearing for a high-performance placement head in printed circuit board production with a cycle frequency of 18 start/stop movements per second and up to 120 million revolutions over five years. The service life is defined as ten years. The bearing must be free from clearance in all directions at 70°C so that the components can be fitted precisely.
Franke special bearing assembly LDB0110. Aluminium (Dispal) is used as the material for the inner and outer ring. It has almost the same thermal expansion coefficient as steel, facilitating constant unit set values across the entire temperature range.
Customer-specific design, which meets all requirements with regard to size, material and mounting dimensions. The integrated bearing element has a small cross section, giving the customer a compact, but nevertheless lightweight design. Franke is the only manufacturer worldwide that can satisfy these specifications.
