Hollow spindle stop for spindle Ø 32–41 mm — rear-insert, adjustable clamping

The Hollow spindle stop for spindle Ø 32–41 mm is a rear-mounted clamping device for hollow spindles that secures tooling by radial jaw pressure and allows axial repositioning using a special key.

Rear insertion for easy fitting Radial jaw clamping for secure seating Adjustable length with special key

Precision clamping for stable machining

The device provides radial jaw clamping that is driven by a clamping screw, pressing the jaws uniformly against the inner wall of the hollow spindle. This mechanism minimises run-out and reduces vibration, delivering a secure seating that supports consistent machining tolerances. For shops handling repetitive turning or milling setups, the resulting increase in stability translates into fewer rejects and less rework, which improves process reliability.

Fast installation and simple length adjustment

Designed for rear insertion, the stop is inserted into the hollow spindle and tightened with a special key. Tightening the clamp locks the unit in place; releasing the key allows smooth axial movement for fine positional adjustment. This workflow shortens setup times and provides repeatable positioning without the need for complex fixtures. The combination of quick fitting and tool-free axial fine-tuning supports efficient changeovers in busy workshops.

Robust design built for everyday workshop use

Constructed for clamping tasks in standard hollow spindles with diameters between Ø 32–41 mm, the stop is suitable for general workshop environments and industrial applications where reliable holding power is required. The straightforward mechanical design minimises maintenance requirements and avoids unnecessary complexity, ensuring long service intervals and dependable performance under frequent use. The use of a dedicated tightening tool guarantees consistent torque and repeatable clamping force.

FAQ

How is the stop secured inside the hollow spindle?
The TECWERK hollow spindle stop is tightened with a clamping screw using the supplied special key; the screw forces the radial jaws against the inner wall to ensure a secure fit.

Can the stop be repositioned without removing it from the spindle?
Yes. Releasing the special key frees the jaws and allows axial repositioning, so the stop can be shifted in length while remaining inserted.

What spindle diameters does this stop support?
The device fits hollow spindles with inner diameters of Ø 32–41 mm, providing consistent clamping across that range.

Is the clamping mechanism repeatable for multiple setups?
The mechanical jaw system with key-operated tightening offers repeatable clamping and positioning suitable for serial setups and frequent tool changes.

Which applications are best suited to this type of stop?
This hollow spindle stop is appropriate for workshop and industrial clamping tasks where secure, low-runout holding is required for turning, milling or other machining operations.
