Frequently asked questions
What is the FL 315 - D8 spindle flange used for?
It is a flange for mounting chucks on metal lathes, with a diameter of Ø 315 mm and a D8 camlock fitting.
It allows for secure attachment of the chuck to the lathe spindle nose according to FL standards (DIN 55029 external flange camlock). 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 camlock according to DIN 55029. The FLD has a central drawbar camlock according to DIN 55027 (faster 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 mounting.
What does the D8 camlock indicate?
The D8 (Camlock) code indicates the quick-release system: the number (e.g., D3, D4, D5, D6, D8, D11, D15) identifies the standard camlock size.
For correct compatibility, check the camlock 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 flanges.
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 disassembly of the existing chuck, thorough cleaning of the lathe spindle nose, application of 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 the reference point (usually a notch or line); do not force with tools. Krollit provides technical documentation and telephone support for mounting.
