MAV 2008

Product catalog summary

Overview: This document provides technical specifications and performance data for MAV 2008 shrink discs, focusing on dimensions, screw sizes, and performance metrics. It includes details on the connection of outer hollow shafts to inner shafts, transmissible torque, and axial load capacities.

Specifications:

Dimensions: Various sizes are listed with specific measurements for diameter, length, and other critical dimensions.
Screws: Hexagonal head cap screws, grade A2-70, are used, with sizes ranging from M5 to M16 depending on the application.
Materials: Components are primarily made from stainless steel series AISI 400.

Performance:

Torque and Load: Transmissible torque ranges from 310 to 34,400 Nm. Axial load capacities are specified, with adjustments for different material combinations.
Contact Pressure: Detailed for both inner and outer shafts, with specific pressure values provided.

Design Features:

Three-part design with non-self-locking tapers.
Lubrication with FDA-approved food-grade paste, class H-1.
Outer hollow shaft bore and inner shaft contact surfaces are lubricant-free and dry.

Installation and Tolerances:

Outer hollow shaft tolerances are specified as h8 or f7, with a minimum clearance of 0.017 mm to prevent installation issues.
Surface finish requirements are between 0.8 ≤ Ra ≤ 3.2 µm.

Recommendations:

For half HC and HT versions, torque and axial load values are reduced to 50% of the listed values.
Consult MAV Technical Department for advice when using different materials for shafts.

Additional Information: The document notes that performance values are subject to change without prior notification and advises consulting MAV for the latest specifications.
