Precision Is Never an Accident - 0.0005–0.0008 mm Manufacturing Tolerance

Every Numeno ring begins with precision—and every finished ring is verified before it reaches our customers.

To ensure that every component meets our manufacturing standards, we perform dimensional inspections using high-precision measuring equipment. These measurements help verify that each ring conforms to its intended geometry and maintains the consistency required for smooth rotational performance.

In this inspection, the measured dimensions are:

• Inner Diameter (ID): 23.0190 mm
• Outer Diameter (OD): 27.6250 mm

The measurement process also demonstrated an extremely small dimensional deviation during inspection, reflecting the consistency of our manufacturing process.

Why does this matter?

Our bearing ring contains multiple precision-machined components working together. Even tiny dimensional differences can influence rotational smoothness, fit, and long-term durability. Careful measurement is therefore an essential part of our quality control process.

Rather than relying solely on design specifications, we verify the finished product with precision measuring equipment to ensure every ring meets our standards before leaving the factory.

This commitment to engineering, manufacturing accuracy, and continuous quality improvement is part of what makes every Numeno ring unique.
