The smallest outer diameter available is 20 mm, with a corresponding inner diameter of 10 mm and a height range of 5–20 mm, all within a tolerance of ±0.2 mm.
As the outer diameter increases, the tolerances become progressively larger. For example, diameters of 20–40 mm carry a tolerance of ±0.2 mm, while larger diameters such as 250–300 mm have tolerances of ±1.2 to ±1.5 mm for outer and inner diameters.
The table lists standard inner diameter options for each outer diameter size. For custom or non-standard inner diameters, it is recommended to contact the manufacturer directly to discuss feasibility and applicable tolerances.
Not always. For smaller sizes (up to 120 mm outer diameter), the height tolerance matches the diameter tolerance. However, for larger sizes such as 150 mm and above, the height tolerance is tighter — for instance, an outer diameter of 200 mm has diameter tolerances of ±1.0 mm but a height tolerance of only ±0.8 mm.
For the 300 mm outer diameter size, the available height range is 10 mm to 150 mm, with tolerances of ±1.5 mm for the outer and inner diameters and ±1.0 mm for the height.
The 80 mm outer diameter offers the most inner diameter options, with three available sizes: 50 mm, 60 mm, and 70 mm, providing greater flexibility for various application requirements.
