Frequently Asked Questions
What is the FLD 400 - D8 chuck flange used for?
It is a flange for mounting the chuck on metal lathes, with a diameter of Ø 400 mm and a D8 mount.
It allows for secure attachment of the chuck to the lathe spindle nose according to the FLD standard (DIN 55027 mount with central tie rod). The Ø 400 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 mount according to DIN 55029. The FLD has a central tie rod mount according to DIN 55027 (quicker to disassemble).
This model is FLD: for maximum compatibility with the lathe, check the standard of the spindle nose. Most professional Bernardo metal lathes use the FLD attachment.
What does the D8 mount indicate?
The D8 (Camlock) code indicates the quick-release system: the number (e.g., D3, D4, D5, D6, D8, D11, D15) identifies the standard size of the mount.
For correct compatibility, check the mount 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 only 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 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 (DLD) system, 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.
