Frequently asked questions
What is the spindle flange FL 160 - D4 used for?
It is a flange for mounting a chuck on metal lathes, with a diameter of Ø 160 mm and D4 mounting.
It allows for secure attachment of the chuck to the lathe spindle nose according to FL standard (DIN 55029 external flange mounting). The Ø 160 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 mounting according to DIN 55029. The FLD has a 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 spindle nose. Most professional Bernardo metal lathes use the FL attachment.
What does D4 mounting indicate?
The D4 code (Camlock) 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 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 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 the 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.
