ER 32 clamping nut with eccentric ring – D 50 mm by TECWERK

The ER32 clamping nut with eccentric ring is a standard-design clamping component for ER collet chucks, providing stable, balanced fastening and compatibility with DIN 6499 systems.

• Standard design with eccentric ring
• Suitable for ER 32 collet chucks
• Thread M40 x 1.5 for secure fastening
• Diameter 50 mm, balanced execution

Reliable clamping for consistent machining

The balanced execution and the integrated eccentric ring reduce runout and support repeatable concentricity, which is essential for precision tasks. With the M40 x 1.5 thread and a nominal 50 mm diameter, this clamping nut secures ER collets reliably, contributing to stable toolholding and fewer reworks. Conformity with DIN 6499 indicates dimensional compatibility with established ER collet systems, so maintenance of concentricity becomes a measurable production benefit rather than an uncertainty.

Seamless integration into ER collet systems

Designed for compatibility with ER 32 collet chucks, the component fits directly into standard collet assemblies and simplifies retrofit or replacement procedures. The eccentric ring permits fine compensation for minor misalignment, helping to maintain concentric clamping without complex adjustments. For workshops and small production lines this means quicker set-ups and improved process stability, while service engineers benefit from straightforward interchangeability when aligning spindles or replacing worn components.

Quality-filtered supply and workshop-focused service

Sourced under the TECWERK designation and supplied via Metav Werkzeuge, the part is backed by a distribution approach that emphasises availability and traceable quality. Metav’s Emmerich hub acts as a quality filter for the European market, supported by an extensive range of precision tools and workshop equipment. This supply chain reliability reduces downtime risk and allows procurement teams to consolidate suppliers while keeping precision accessible for everyday workshop demands.
