Frequently asked questions
What is the FL 250 - D6 spindle flange used for?
It is a flange for mounting the chuck on metal lathes, with a diameter of Ø 250 mm and D6 camlock.
It allows the chuck to be securely attached to the lathe spindle nose according to FL standard (DIN 55029 external flange camlock). The Ø 250 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 an external camlock according to DIN 55029. The FLD has a central drawbar camlock 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 D6 camlock indicate?
The D6 code (Camlock) indicates the quick-locking system: the number (e.g., D3, D4, D5, D6, D8, D11, D15) identifies the standard size of the camlock.
For correct compatibility, check the camlock of your lathe: D3-D5 for small/medium lathes, D6-D8 for medium-large lathes, D11-D15 for heavy industrial lathes.
Is this an original Bernardo spare part?
Yes, Krollit has been an official Bernardo distributor since 2007 and supplies exclusively original flanges for Bernardo lathes and DIN compatible ones.
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 dismounting the existing chuck, thoroughly cleaning the lathe spindle nose, applying a light layer of oil, and tightening with the torque indicated in the manual.
For lathes with the 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.
