Frequently asked questions
What is the FLD 200 - D4 spindle flange used for?
It is a flange for mounting the chuck on metal lathes, with a diameter of Ø 200 mm and D4 mounting.
It allows the chuck to be securely fastened to the lathe spindle nose according to FLD standards (DIN 55027 central drawbar mounting). The Ø 200 mm diameter corresponds to the nominal diameter of the compatible chuck.
What is the difference between FL and FLD series?
The FL (Ø flanges) has external mounting according to DIN 55029. The FLD has central drawbar mounting according to DIN 55027 (faster 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 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 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 disassembling 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 up to the reference (usually a notch or line); do not force with tools. Krollit provides technical documentation and telephone support for mounting.
