Locking assembly BAR bore 8mm QPQ-coated PN: 61570800
Material: Steel.
– 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.
