Frequently Asked Questions
What is the FLD 630 - D11 spindle flange used for?
It is a flange for mounting the chuck on metal lathes, with a diameter of Ø 630 mm and a D11 fitting.
It allows secure attachment of the chuck to the lathe spindle nose according to FLD standards (DIN 55027 central pull stud fitting). The Ø 630 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 fitting according to DIN 55029. The FLD has a central pull stud fitting 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 D11 fitting indicate?
The D11 code (Camlock) indicates the quick-release system: the number (e.g., D3, D4, D5, D6, D8, D11, D15) identifies the standard size of the fitting.
For correct compatibility, check the fitting 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 only supplies original flanges for Bernardo and DIN-compatible lathes.
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 a Camlock system (DLD), the cams should be closed by hand until they reach the reference point (usually a notch or line); do not force with tools. Krollit provides technical documentation and telephone support for mounting.
