In detail
Bearing type
Franke bearing elements in type LER are designed for medium rotational speeds and accuracies. They run smoothly, possess high dynamism and require just compact mounting space. The straight contact surface ensures simple integration in the mating structure and also a high rigidity. The attractive price makes this bearing element type LER an economic solution.

Characteristics
Bearing elements of the LER type consist of two inner and two outer raceways, along with a plastic cage with retained balls. The race rings are divided at one point to compensate for the temperature expansion factor. They possess compensatory properties for demanding forms of stress. LER are generally mounted free from clearance. The preload can be defined individually to meet the specific requirement. See ‘Technical information’ for the adjustment methods.
