27mm Hollow Spindle Stop Adjustable Clamping Range 27mm, Internal Jaw Lock - TECWERK

Benefit from a secure, rear-fit clamping solution that accommodates a 0–27 mm span and locks firmly against the inner wall of the spindle. The combination of reliable expansion jaws and simple axial adjustment with a special key supports repeatable, time-saving set-ups; order directly via Metav Werkzeuge or consult our specialists for application advice.

Hollow spindle stop for spindle Ø20–27 mm — TECWERK rear-fit expandable stop

The Hollow spindle stop for spindle Ø20–27 mm is a rear-insertable clamping device designed to secure position inside hollow spindles for turning and machining applications.

• Rear-fit insertion for hollow spindles
• Adjustable clamping range 0–27 mm
• Expansion jaws ensure secure seating
• Quick release and axial adjustment with key

Secure clamping for repeatable set-ups

The stop provides secure seating by expanding its jaws against the spindle’s inner wall when the clamping screw is tightened. This mechanical expansion creates a positive, frictional hold that reduces axial play and supports repeatable set-ups during machining operations. The design translates to fewer re-adjustments between operations and more consistent component tolerances, which is particularly valuable in production environments where repeatability is critical.

Time-saving rear-fit installation and release

Installed from the rear of the hollow spindle, the device is tightened and released using a special key, allowing straightforward assembly without the need to access the spindle front. The rear-fit insertion saves set-up time on machines with limited front access and simplifies changeover procedures. When the key is used to loosen the clamping screw, the stop can be moved axially for fine positional adjustment, enabling quick corrections without full disassembly.

Flexible clamping range for diverse spindles

With an adjustable clamping range of 0–27 mm, the stop suits a variety of hollow spindle inner diameters commonly encountered in light to medium machining tasks. The expandable jaws adapt to the internal bore, delivering stable contact across that span without requiring additional adapters. This flexibility reduces the number of different stops or adapters needed in the tooling inventory, streamlining workshop logistics.

Robust operation with intuitive control

Operation relies on a simple mechanical principle: turning the clamping screw forces the jaws outward to press against the spindle bore, ensuring a firm hold. This straightforward mechanism is easy to inspect and service, and it avoids complex hydraulic or pneumatic components that would require additional maintenance. The clear cause-and-effect behaviour—tighten for clamping, loosen for release—supports safe, predictable use in production and maintenance contexts.

FAQ

How is the stop installed in the machine?
The stop is inserted from the rear of the hollow spindle and secured by tightening the clamping screw with the supplied special key; this causes the expansion jaws to press against the inner wall for a firm hold.

Which spindle diameters are covered by this device?
The device accommodates internal spindle diameters within the 0–27 mm range and is therefore suitable for spindles specified as Ø20–27 mm as indicated in the product description.

Can the position be adjusted once fitted?
Yes. By loosening the clamping screw with the special key, the stop can be released and moved axially to fine-tune the position before re-tightening to lock it in place.

Is this device suitable for high-precision set-ups?
The expansion-jaw mechanism provides stable, repeatable contact against the spindle bore, which supports precision set-ups where axial stability and repeatability are important.

What tool is required to operate the clamping screw?
Operation requires the specified special key mentioned in the product details; this key is used both to tighten the jaws for clamping and to loosen them for axial adjustment.
