Frequently asked questions
What is the FL 500 - D11 chuck flange used for?
It is a flange for mounting the chuck on metal lathes, with a diameter of Ø 500 mm and D11 mounting.
It allows secure attachment of the chuck to the lathe spindle nose according to FL standards (DIN 55029 external flange mounting). The Ø 500 mm diameter corresponds to the nominal diameter of the compatible chuck.
What is the difference between FL and FLD series?
The FL (Ø flange) has external mounting according to DIN 55029. The FLD has central drawbar mounting according to DIN 55027 (quicker to disassemble).
This model is FL: for maximum compatibility with the lathe, check the standard of the chuck nose. Most professional Bernardo metal lathes use the FL attachment.
What does D11 mounting indicate?
The D11 (Camlock) code indicates the quick-release system: the number (e.g., D3, D4, D5, D6, D8, D11, D15) identifies the standard size of the mounting.
For correct compatibility, check the mounting of your lathe: D3-D5 for small/medium lathes, D6-D8 for medium-large lathes, D11-D15 for heavy industrial lathes.
Is it an original Bernardo spare part?
Yes, Krollit has been an official Bernardo distributor since 2007 and exclusively supplies original flanges for Bernardo lathes and compatible DIN standards.
Original flanges comply with the machining tolerances required by the DIN standard to ensure concentricity and balance of the chuck. Do not use non-original flanges for precision machining.
How is the flange mounted on the lathe?
Mounting requires disassembling the existing chuck, thoroughly cleaning the lathe spindle nose, applying a light coat of oil, and tightening with the torque indicated in the manual.
For lathes with a Camlock system (DLD), the cams should be closed by hand until the reference point (usually a notch or line); do not force with tools. Krollit provides technical documentation and telephone support for mounting.
