TECWERK ER16 Collet Nut (D 28, M22 x 1.5) – Sliding-bearing, SW 25 mm

A TECWERK ER16 collet nut for ER collet chucks, designed as a balanced, sliding-bearing version to ensure stable clamping in precision machining environments

• Balanced sliding-bearing construction for smooth clamping
• Compatible with ER 16 collet chucks to DIN 6499
• Thread M22 x 1.5 for standardised spindle interfaces
• Spanner width SW 25 mm, outer diameter D 28 mm

Reduce runout for consistent machining results

The balanced design of this collet nut delivers a measurable improvement in precision by lowering eccentricity during rotation. Fitted to ER collet chucks, the balanced execution minimises vibration and helps maintain tool alignment, which in turn supports a more consistent surface finish and reduced wear on cutting edges. As a result, production runs can achieve tighter tolerances with fewer reworks.

Straightforward compatibility and installation

Built to interface with ER 16 systems, the component features a standard M22 x 1.5 thread and an outer diameter of D 28 with a spanner width of SW 25 mm, making it suitable for common spindle and chuck configurations. Compliance with DIN 6499 ensures interchangeability with established ER collet chuck setups, simplifying retrofits and replacements without the need for additional adapters. The clear mechanical specification shortens setup time and supports reliable repeatability.

Sliding-bearing execution for smooth, reliable clamping

The sliding-bearing construction reduces friction between mating parts, producing gentler axial guidance during tightening and release. This lowers the risk of galling and contributes to quieter operation during tool changes. The result is a clamping interface that requires less frequent adjustment while maintaining stable holding force, which benefits both manual and automated tool-change workflows in the workshop.

Practical workshop benefits and maintenance guidance

Delivered as a single unit, the collet nut integrates directly into ER 16 toolholding systems and supports predictable performance across batches. Regular inspection of the thread and bearing surfaces will preserve the integrity of the fit and the balanced behaviour. For shops aiming to improve process stability, the nut serves as a targeted upgrade to reduce variability at the spindle and increase overall uptime.

FAQ

What materials is this collet nut compatible with? This collet nut is specified for use with ER 16 toolholding systems; material compatibility depends on the chosen collet and cutter rather than the TECWERK ER16 collet nut itself.

How does the balanced execution benefit spindle performance? Balanced execution reduces centrifugal forces at speed, lowering vibration and helping to maintain tool alignment; the balanced design of this nut contributes to improved surface finish and longer tool life.

What thread and spanner size are required for installation? The component uses an M22 x 1.5 thread and requires a SW 25 mm spanner for tightening and removal, matching common ER 16 interface standards.

Is this nut compatible with standard ER 16 collet chucks to DIN 6499? Yes, the nut is designed for compatibility with ER 16 collet chucks and references DIN 6499 for interchangeability.

How should the nut be maintained to ensure longevity? Regular inspection and cleaning of the thread and bearing faces, plus light lubrication where appropriate, will preserve the sliding-bearing surfaces and the balanced behaviour of the nut.
