Frequently asked questions
What is the FLD 315 - D8 spindle flange used for?
It is a flange for mounting a chuck on metal lathes, with a diameter of Ø 315 mm and a D8 taper.
It allows secure chuck attachment to the lathe spindle nose according to FLD standards (DIN 55027 central pull-stud taper). The Ø 315 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 taper according to DIN 55029. The FLD has a central pull-stud taper 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 the D8 taper 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 taper.
For correct compatibility, check the taper 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 nose, applying a light coat 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 point (usually a notch or line); do not force with tools. Krollit provides technical documentation and phone support for mounting.
