ER collet nut ER25 Ø42 mm – balanced sliding-bearing clamping nut by TECWERK

The ER collet nut ER25 Ø42 mm is a balanced, sliding-bearing clamping component designed for secure fastening in ER collet chuck systems.

• Balanced design for high-speed machining
• Sliding-bearing for smooth axial guidance
• Thread M32 x 1.5 for ER25 collet chucks
• Conforms to DIN 6499, diameter 42 mm

Improved clamping reliability for continuous production

The balanced design and sliding-bearing construction reduce axial play and minimise vibration during rotation. This results in reduced runout, more consistent clamping force and less wear on the toolholder and spindle, which directly supports longer production runs and fewer unplanned stoppages. For workshops and small-scale production lines, these attributes translate into improved process stability and predictable repeatability.

Engineered for precise fit and interchangeability

The collet nut uses an M32 x 1.5 thread and is dimensioned for Ø42 mm engagement, matching the geometry specified in DIN 6499 for ER systems. Conformity to this standard ensures compatibility with established ER25 collet chucks and simplifies replacements or retrofits. In practical terms, adherence to the standard reduces setup time and eliminates uncertainty when sourcing replacement clamping components for existing toolholders.

Compatibility, installation and operational benefits

Designed specifically for ER25 systems, the component is suitable for integration into ER collet chucks where a balanced execution is required. The sliding-bearing version provides smoother axial guidance than rigid nuts, aiding consistent collet compression and release under cyclical loads typical in milling and turning operations. If the precise fit or suitability for a specific chuck type is uncertain, Metav Werkzeuge’s consultants can verify compatibility to ensure the component meets the intended operational demands.
