Material: Steel, QPQ coated. High corrosion resistance,improved
fatigue strength, primarily food safe.

Clamping bush for medium high torques; not self-centering.

Fit: Shaft h8. Hub H8. Surface roughness hub/shaft R_z
max. 12.5 µm.

Mounting: Slightly oil the clamping set before mounting, do not
use molibdenum disulphide or grease. Tighten the screws evenly and
crosswise in several steps.

Demounting: Due to the large cone angle, the clamping set
releases on its own after the screws have been fully unfastened.

There are three larger threads cut into the front ring, which serve to
remove this ring.

Ts – Fastening Torque

T – Transmittable Torque

F – Transmittable Axial Force

P – Surface Pressure onto Hub

QPQ Surface Properties: Very good corrosion resistance,
betterthan hard chrome or chem. nickel. Corrosion resistance in the salt
spraytest SS CASS in accordance with DIN 50021. Layer thickness of 10 –
25 µmpossible. For medium operational demands we recommend a layer
thicknessof 15 µm at a 90 minute treatment. Only very small changes in
dimensions(only 5 µm), as the surface modification is achieved through
diffusionand 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
completelysafe to use with food as long as there is no contact with any
acidicsubstances with a pH-value of = 4.
