Hollow spindle stop Ø 25–33 mm — TECWERK internal expandable clamping stop

The Hollow spindle stop Ø 25–33 mm is a rear‑inserted internal clamping stop designed for axial positioning inside hollow spindles, expanding to lock securely against the inner wall for repeatable machining operations

• Rear-inserted design for hollow spindles
• Expansion clamp secures to inner spindle wall
• Special key allows tightening and release
• Adjustable axial position after release

Precise, repeatable positioning for hollow‑spindle machining

Engineered for applications that demand reliable axial stops, this internal clamping stop delivers secure seating by pressing its jaws against the spindle bore when the clamping screw is tightened. The rear insertion method lets the component be fitted from the back of the hollow spindle, removing the need for external fixtures. As a result, the device minimises axial play and supports consistent positioning during turning, milling or light assembly tasks, improving process reproducibility and reducing rework.

How the expansion mechanism converts torque into a secure hold

The clamping action is achieved by a threaded clamping screw: turning the screw with the supplied special key forces the jaws outward so they bear on the internal surface of the spindle. This simple mechanical principle creates a high‑friction contact that resists axial movement without complex hydraulic or pneumatic systems. For operators with limited metrology training, the mechanism is straightforward to use and maintain, while production engineers benefit from a compact solution that reduces setup time between part runs.

Fast axial adjustment that keeps production moving

Once the clamping screw is released with the special key, the stop can be shifted axially to the new position and re‑clamped in seconds. This adjustable axial position capability supports short changeover times and flexible fixturing strategies. For workshops aiming to increase throughput, the combination of quick release and secure reclamping helps keep cycle times low and tooling utilisation high, delivering a tangible efficiency advantage on mixed production lines.

Durable, low‑maintenance design suited to workshop environments

Built for use inside hollow spindles, the stop’s functional design focuses on robustness and serviceability rather than unnecessary complexity. The rear installation and mechanical expansion minimise exposed parts and simplify cleaning and inspection. Routine checks consist of verifying the clamping action and ensuring the special key operates freely; these simple maintenance steps support long‑term reliability and steady performance across batches and shifts.

FAQ

What spindle bores are supported by this stop?
The hollow spindle stop is suitable for spindles with an internal diameter of approximately 25–33 mm as indicated on the product label.

How is the stop fixed inside the spindle?
Fixing is achieved by tightening the clamping screw, which expands the jaws until they press against the inner wall; the operation is carried out using the supplied special key.

Can the stop be repositioned quickly between operations?
Yes, releasing the clamping screw with the special key allows axial repositioning and rapid re‑clamping for fast changeovers.

Is specialised equipment required for installation?
No specialised equipment is needed; the device is inserted from the rear and secured with the special key described in the product details.

Does the stop provide a repeatable axial reference?
The expansion mechanism offers a firm contact with the spindle bore, providing a repeatable axial reference suitable for many workshop applications.
