Standard ER chuck -> Collets are not inserted 100 % into the chuck.

- Balance quality G at rotational speed: G 2.5 at 25,000 rpm
- Concentricity: ≤ 3
- Machining strategy: HSC; HPC
Description
Version:
External and internal tapers are ground. All shanks are hard turned for smooth running. Including RFID / Balluffchip bore, high-performance clamping nut (up to 25000 rpm).
Advantage:
- Excellent concentricity in the system (chuck + collet + clamping nut), 3µm radial run-out with a 2µm collet, 6µm radial run-out with a 5µm collet.
- Extremely strong holding force (up to factor 2 better than the standard ER chuck).
- Vibration reduction effect due to 2-part clamping nut.
Application:
For clamping tools with plain shank in collets to DIN 6499 − Form A and B.
Supplied with:
Precision clamping nut.
Optional extras:
Pull studs (PS) No. 308760 – 308802, PS wrenches No. 308820 – 308835, ER chuck keys No. 309757, 309758 (for 11M and 16M); ER collets Fahrion No. 308901 – 309434. ER collets No. 308901 − 309432, hook spanner 628400 or torque wrench 309749 or 628520.
Note:
- Clamps only nominal ⌀ up to shank ⌀ tolerance h 10.
- Do not use the clamping nut in combination with a sealing washer.
- Use it in only combination with Fahrion collets.
- The blue design ring must be removed for Fahrion HP 2µm ER collets.
