40-50mm Hollow Spindle Stop With Internal Clamping Screw, Adjustable Length - TECWERK

Take advantage of a compact internal stop that expands to grip the spindle interior, covering a 0–50 mm clamping range and locking securely with a tightening screw operated by a special key; order the device via Metav Werkzeuge or consult the Metav team for application advice.

Hollow spindle stop for spindle Ø 40–50 mm · TECWERK

A Hollow spindle stop for spindle Ø 40–50 mm, engineered to provide a secure axial location inside hollow spindles for reliable machining set-ups.

• Expands to grip inner spindle wall
• Clamping range 0–50 mm
• Tool released and adjusted with special key
• Ensures secure axial positioning

Precision internal clamping for repeatable set-ups

The device is designed to be inserted from the rear into a hollow spindle and fixed by tightening a screw, which forces the clamping jaws outwards against the inner wall. This mechanism delivers secure seating during axial loading and prevents unwanted movement, improving repeatability across multiple components. The simple mechanical principle avoids complex electronics and provides a robust solution for frequent set-up changes in production environments.

Fast installation and adjustable positioning to save time

Installation and adjustment are carried out with a special key, allowing the stop to be tightened, released and shifted in length without disassembly of the spindle. The clear mechanical operation reduces set-up time and minimises machine downtime, which contributes to faster throughput and fewer rejects. The adaptable expansion principle makes the device suitable for tasks that require quick repositioning and consistent axial stops, supporting efficient workflow in machine shops and maintenance departments.

Designed for workshop reliability and safe handling

Constructed for insertion into hollow spindles with a working span of 0–50 mm, the stop gives a secure internal anchor point for through-spindle operations or for applications where external fixturing is impractical. The tightening action converts rotational torque from the key into radial force on the jaws, ensuring a stable hold without relying on external clamps. Supplied as a single unit, the component is straightforward to store and fits common service routines for spindle-mounted tooling.

FAQ

What clamping range does the hollow spindle stop cover?
The hollow spindle stop by TECWERK covers a clamping range of 0–50 mm, suitable for spindles within that diameter window.

How is the device installed and adjusted?
The stop is inserted from the rear into the hollow spindle and tightened with a special key; loosening the key releases the jaws and allows axial repositioning.

Can the stop maintain position under axial load?
Yes, the tightening screw forces the jaws against the inner wall of the spindle so that the stop provides a secure axial hold during machining.

Is the product supplied ready to fit?
The TECWERK hollow spindle stop is supplied as a single unit and is ready for insertion and clamping with the appropriate key.

Which applications are typical for this type of stop?
This internal stop is typically used where an internal axial locate is needed—such as through-spindle operations, machining of long workpieces, or situations where external fixturing is impractical.
