Frequently Asked Questions
Q
What do the outer diameter and inner diameter values in the table represent?
A
The outer diameter refers to the total external measurement of the ring or component, while the inner diameter refers to the measurement of the hollow center. Both values are listed in millimeters (mm) and define the basic dimensional specifications of each size variant.
Q
Why do tolerance values increase as the outer diameter gets larger?
A
Larger components naturally require wider tolerance ranges due to the increased difficulty of maintaining precision during manufacturing at greater scales. For example, a 20mm outer diameter has a tolerance of ±0.2mm, while a 300mm outer diameter allows ±1.5mm, which is still proportionally tight relative to the part size.
Q
Can I request a custom inner diameter that is not listed in the table?
A
Yes. The inner diameter options shown (e.g., 15/20, 20/30) represent standard configurations. Custom inner diameter specifications may be available upon request, subject to engineering review and minimum order quantity requirements. Please contact our technical team for more details.
Q
What is the height range, and can intermediate heights be specified?
A
The height range (e.g., 5～20mm, 10～150mm) indicates the minimum and maximum available heights for each diameter size. Intermediate heights within the listed range can generally be specified to meet your application requirements. Please consult with our team to confirm availability for your specific height.
Q
Are the tolerance values the same for all dimensions at a given size?
A
Not always. For most sizes, the outer diameter, inner diameter, and height share the same tolerance value. However, for larger sizes (150mm and above), the height tolerance may differ from the diameter tolerances — for example, at 150mm outer diameter, the diameter tolerance is ±0.8mm while the height tolerance is ±0.5mm.
Q
What materials are these components available in?
A
The dimensional specifications in this table apply across multiple material options. Available materials may include various grades of metal, plastic, or composite materials depending on the application. Please refer to the product material specifications page or contact our sales team for material-specific guidance.
