LER Technical Information
Product type
• 4 race rings with profiled raceways
• Plastic ball cage with retained balls
• 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
• Maximum possible integration capacity
• Series application to meet cost constraints
• Greatest possible flexibility of preload, runability and diameter ranges
• 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.
Diameter Range
Infinitely variable from 70 to 2000 mm
Mating structure
The bearing element mounted determines the overall con- struction’s load bearing capacity. Hence the mating con- struction can be made of alternative materials such as steel, aluminium or plastic. Axial and radial accuracy (see diagram on left) are defined to a substantial extent by the mating components. These properties can be enhanced by boosting the accuracy of manufacture.
