Locking assembly COM-A bore 40mm size 40-65 QPQ-coated
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.
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.
