O形圈槽 規格表
2種規格資料
O型圈槽尺寸表規定了槽的寬度和深度。運動用槽壓縮率8~16%使摩擦最小化，固定用槽15~30%確保密封可靠性。加工時須遵守角部R和表面粗糙度要求。
常見問題 (FAQ)
What is the difference between dynamic groove and static groove dimensions?
Dynamic grooves are for O-rings in sliding contact (pistons, rods). Static grooves are for non-moving seals (flanges, covers). Groove dimensions (width, depth) and compression ratios differ.
What is the recommended surface roughness for O-ring grooves?
Dynamic groove bottom: Ra 0.4–0.8; static grooves: Ra 1.6–3.2. Groove sides: Ra ≤1.6. Poor surface finish causes O-ring wear and leakage.
