    ? Frequently Asked Questions
    Q What is the outer diameter range available in the standard dimension table?
    The standard dimension table covers outer diameters ranging from 20mm up to 300mm, providing a wide selection to suit various application requirements.
    Q Can I choose different inner diameters for the same outer diameter?
    Yes. Most outer diameter sizes offer multiple inner diameter options. For example, an outer diameter of 80mm is available with inner diameters of 50mm, 60mm, or 70mm, giving you flexibility for different bore requirements.
    Q How does the dimensional tolerance vary with size?
    Tolerances increase with larger dimensions. Smaller sizes (OD 20–40mm) maintain a tight tolerance of ±0.2mm, while larger sizes (OD 250–300mm) have tolerances up to ±1.5mm for outer and inner diameters, and ±1.0mm for height.
    Q Are the height tolerances the same as the diameter tolerances?
    Not always. For larger sizes, the height tolerance is typically tighter than the diameter tolerance. For instance, at OD 150mm, the diameter tolerance is ±0.8mm while the height tolerance is ±0.5mm, ensuring more precise axial control.
    Q What is the maximum height available for each outer diameter?
    The maximum height increases with the outer diameter. For example, OD 20mm supports heights up to 20mm, while OD 300mm supports heights up to 150mm. Each size has a defined height range starting from a minimum of 5mm or 10mm.
    Q Can custom dimensions outside this table be manufactured?
    The table lists standard available specifications. For dimensions or tolerances outside the listed ranges, it is recommended to contact the manufacturer directly to discuss custom production possibilities based on your specific technical requirements.
