Locking Assemblies BAR, QPQ-Coated, boreholes 5 - 50 mm
- For fixing a hub on a shaft. - QPQ coated: High corrosion resistance, improved fatigue strength, primarily food safe (further information see below). - For medium torques. - Self-centering. - Slight axial offset possible during assembly.
Fit, Surface: Due to the special design of the BAR clamping set even rough fits can be bridged with excellent self centering capacity. Shaft and hub up to Quality h8/H8. Surface finish for shaft and hub Rz < 12 µm.
QPQ Surface Properties: Very good corrosion resistance, better than hard chrome or chem. nickel. Corrosion resistance in the salt spray test SS CASS in accordance with DIN 50021. Layer thickness of 10 - 25 µm possible. For medium operational demands we recommend a layer thickness of 15 µm at a 90 minute treatment. Only very small changes in dimensions (only 5 µm), as the surface modification is achieved through diffusion and not application. Surface hardness same as clamping set material = 350 HV. Improved wear resistance, no fretting corrosion, no cold shut. Increased endurance strength, sometimes up to 100% higher. Is completely safe to use with food as long as there is no contact with any acidic substances with a pH-value of = 4.
