ER 40 collet nut D63 mm with eccentric ring — TECWERK

An ER 40 collet nut with eccentric ring for ER collet chucks, supplied in a standard, dynamically balanced design for reliable clamping in workshop and production applications

• Dynamically balanced design
• Eccentric ring for precise seating
• M50 x 1.5 thread for direct spindle fit
• Compatible with ER 40 collet chucks

Secure clamping with measurable runout control

The primary advantage of this clamping nut is its balanced design combined with an eccentric ring, which together improve seating consistency and reduce unbalance during rotation. In practical terms, the balanced execution lowers vibration and contributes to more predictable machining outcomes, especially at medium spindle speeds. The combination of M50 x 1.5 thread and a 63 mm diameter ensures a secure mechanical interface with standard ER systems, so the mechanism focuses on repeatable clamping precision rather than frequent adjustment.

Clear compatibility and standard conformity for easier procurement

Compatibility is straightforward: the component is made for ER 40 collet chucks and follows DIN 6499 conventions where applicable, simplifying selection and parts management. The standard format and marked dimensions make inventorying and assembly more efficient in workshop environments. For teams consolidating suppliers, the standardised interface reduces the need for custom adaptors and speeds up changeover between toolings, helping to maintain production flow.

Robust design for everyday workshop use

Built as a standard execution part for routine use, the nut’s geometry and the eccentric seating ring are engineered to withstand normal workshop handling while maintaining the required clamping force. This design choice supports operational reliability and reduces downtime caused by loosening or misalignment. The straightforward construction also permits straightforward inspection and verification, which is useful for quality control processes in small to medium manufacturing setups.

Practical installation and inspection advice

Installation requires matching the M50 x 1.5 spindle thread and an ER 40 collet chuck. When fitting, ensure the eccentric ring is correctly oriented to achieve uniform clamping pressure; incorrect seating can cause asymmetry in the clamping force. Periodic visual checks of thread condition and the eccentric ring seating are sufficient for most users to maintain performance; for detailed runout verification, measuring equipment that reads spindle runout will confirm the benefit of the nut’s balanced design without demanding specialist procedures.
