Description

  1. Basic Model: SFU1605, BK12-BF12 (indicates structure, diameter, lead)
  2. Nominal Diameter (d₀): Outer diameter of the screw shaft, unit: mm (e.g., 16mm, 20mm)
  3. Lead (P): Axial distance the nut moves per 360° rotation of the screw, unit: mm (e.g., 5mm, 10mm)
  4. Accuracy Class: Complies with ISO standards (e.g., C3, C5, C7) – higher class means better positioning precision
  5. Dynamic Load Rating (Cₐ): Maximum axial load for 1 million cycles without damage, unit: kN
  6. Static Load Rating (C₀ₐ): Maximum static axial load without permanent deformation, unit: kN
  7. Maximum Rotational Speed (nₘₐₓ): Limit speed to avoid resonance/overheating, unit: rpm
  8. Operating Temperature Range: Usable temp interval, typically -20°C ~ +80°C (varies by lubricant/seal)
  9. Shaft Length (L): Total length of the screw shaft, unit: mm
  10. Nut Type: e.g., Single nut, Double nut (for anti-backlash); with/without seal
