Cylindrical Roller Bearings (LVB) by Franke GmbH

Product inquiry  

Application example Laser optics on aircraft

Rolling bearings with high rigidity and maximum precision are required for use in aircraft protection. The bearings must be able to compensate for thermal expansion.

Solution
Slewing ring LDB80/295 as a cylindrical roller bearing made of aluminum with a diameter of 295 mm. Another slewing ring in the form of a three-point bearing is also used.

Rolling bearing used
Slewing ring type LVB (customer-specific)

Advantages
The slewing ring LDZ has a radial and axial run-out of 0.03 mm. Weight savings are achieved thanks to the lightweight aluminum design. The load ratings, rigidity and accuracy of the bearing are determined by the races. The second bearing has a bearing angle of 45° (three-point bearing). The outer ring is movable in order to optimally compensate for thermal expansion.
