LEL Specification

Leaders in bespoke engineered bearing & driven rotary solutions

LEL Technical Information

Product type
• 4 race rings with ground raceways

• Plastic ball cage with retained balls
• Franke bearing elements in type LEL meet high standards in terms of runnability and accuracy. Their hardened and CNC-ground raceways, along with the ideal geometric adjustment of ball and raceway radius, lend them outstanding bearing properties.
• Bearing elements in the LEL type permit the greatest possible freedom of bearing design. The standard mounting space is between 5.9 mm and 20.9 mm.
• Race ring thickness of up to 20 mm and bearing sizes up to 50 mm are possible to meet special requirements.


Characteristics
• Maximum possible integration capacity
• Series application to meet cost constraints
• Greatest possible flexibility based on preload, runnability and diameter ranges
• Bearing elements of the LEL 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. LEL 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 construction’s load bearing capacity. Hence the mating construction can be made of alternative materials such as steel, aluminium or plastic. Axial and radial accuracy are defined to a substantial extent by the mating components. These properties can be enhanced by boosting the accuracy of manufacture.

Technical Details
• Material Ball race rings: 54SiCr6, rolling element: 100Cr6, cage: PA12
• Temperature in use: –30 °C to +80 °C, briefly up to +100 °C
• Circumferential speed: max. 5 m/s, without seals max. 10 m/s
• Lubricant grease: Klüber Isoflex Topas NCA52
• Lubricant schedule: Contact us for further information
•Tolerance details: Contact us for further information
