Setting ring 225 mm (hardened gauge steel) – Form C, DIN 2250 / DIN 286 JS4

A Setting ring 225 mm designed as a stable master reference for calibration, fixture alignment and high-precision inspection tasks in workshops and metrology labs

• Hardened gauge steel with lapped finish
• Nominal diameter 225 mm for master references
• DIN 2250 / DIN 286 compliance, tolerance JS4
• Form C profile for versatile calibration use

Reliable reference for reproducible setups

The ring serves as a master reference for setting and checking bore gauges, mandrels and calibration fixtures. Manufactured from hardened and lapped gauge steel, the component resists wear and preserves contact geometry over repeated use, which reduces the need for frequent replacements. With a 225 mm nominal diameter and substantial mass, the ring provides a consistent datum that helps cut setup time and improves repeatability on the shop floor.

Solid construction that reduces measurement uncertainty

A combination of material choice and finishing yields excellent contact behaviour: the lapped surface minimises micro-asperities at the measuring interface and the hardened substrate increases wear resistance. The ring’s mass (approx. 14.5 kg) increases stability during measurement, lowering the influence of incidental vibration. These mechanical properties translate directly into fewer re-checks and a steadier calibration routine, supporting faster throughput in production control.

Standards-based tolerances for traceable results

Compliance with DIN 2250 and DIN 286, specified to tolerance JS4, makes the component suitable for traceable calibration chains and compatibility with standard gauge systems. The stated norm conformity clarifies fit expectations and ensures interchangeability with other calibrated master parts. For quality assurance, this norm-based approach supports documentation and audit processes where reproducible, verifiable measurements are required.

Practical integration for workshop and inspection use

The Form C profile and nominal diameter make the ring adaptable across machine shops, toolrooms and metrology benches where reference rings are used to set internal measuring devices or to verify bore gauges. Its robust design is intended for repeatable handling in routine inspection workflows. The item is categorised among precision gauges and is particularly well suited where stable, standards-conformant references are needed to maintain process control.
