MV 3008

Product catalog summary

Overview: This document provides technical specifications and performance data for MAV 3008 shrink discs, focusing on dimensions, screw performances, and material compatibility.

Specifications:

Dimensions: Various sizes are listed, with specific measurements for diameter, length, and screw size.
Screw Performances: Includes tightening torque (Ma), transmissible torque (Mt), axial load (Fax), and contact pressures (Ps and Ph).
Material: Stainless steel series AISI 400 is specified, with performance values contingent on material compatibility.

Features:

Connection of outer hollow shaft onto inner shaft.
Transmissible torque ranges from 87 to 26,403 Nm.
Low self-locking tapers and two-part design.
Lubrication with FDA-approved food-grade paste.
Specific tolerances and surface finish requirements for shafts.

Composition:

Slotted inner ring with integrated push-off tapped holes.
Outer ring and a set of hexagonal head cap screws, grade A2-70.

Performance Considerations:

Performance values are valid for stainless steel components; different materials may alter these values.
If the inner shaft is standard steel and the outer hollow shaft is stainless steel, Mt and Fax are reduced to 57.14% of listed values.

Fitting Tolerances:

Specific ISO tolerances and maximum clearances are provided for different shaft sizes.

Important Notes:

Information is subject to change without prior notification.
Consult MAV Technical Department for advice on material compatibility and performance adjustments.
