Frequently Asked Questions
What is the FL 200 standard chuck flange used for?
It is a flange for mounting chucks on metal lathes, with a diameter of Ø 200 mm and a standard recess.
It allows secure attachment of the chuck to the lathe spindle nose according to the FL standard (DIN 55029 external flange mounting). The Ø 200 mm diameter corresponds to the nominal diameter of the compatible chuck.
What is the difference between the FL and FLD series?
The FL (Ø flange) has an external mounting according to DIN 55029. The FLD has a central drawbar mounting according to DIN 55027 (quicker to dismantle).
This model is FL: for maximum compatibility with the lathe, check the standard of the chuck's spindle nose. Most professional Bernardo metal lathes use the FL attachment.
What does the standard recess indicate?
The standard code (Camlock) indicates the quick-release system: the number (e.g., D3, D4, D5, D6, D8, D11, D15) identifies the standard size of the recess.
For correct compatibility, check the recess 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 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 a Camlock system (DLD), the cams should be closed by hand until the reference (usually a notch or line); do not force with tools. Krollit provides technical documentation and phone support for mounting.
