Professional FAQ & Selection Guidance

• How does the 95.250.022.3.0 handle dry operation?
• The GD technology keeps seal faces in contact without liquid lubrication, preventing thermal shock during media transitions.
• What is the critical speed limit for compressed air usage?
• Do not exceed 10,000 min⁻¹ when running air only to prevent seal face overheating.
• Why prioritize the 95.250.022.3.0 over standard unions?
• The hybrid bearings reduce friction and heat, preserving the precision of your high-value machining spindle.
• Is this compatible with Minimum Volume Lubrication (MQL)?
• Yes, it supports externally mixed MQL at pressures up to 5 bar.
• What are the signs of filtration failure?
• Concentric scoring on the seal faces indicates particles >50µm are present in your media supply.
