Product catalog summary
Overview
This document provides technical specifications for the rigid shell couplings (Schalenkupplung) offered by VMA® Verbindungs- Mess- und Antriebstechnik GmbH. The couplings are available in two types: slotted (STK-GS) and split (STK-GT), made from stainless steel or burnished steel.

Specifications
  • Material: Stainless steel or burnished steel.
  • Types: STK-GS (slotted) and STK-GT (split).
  • Sizes: Available in various sizes with dimensions provided in millimeters.
  • Dimensions: Length (L), Diameter (D), and Inner Diameter (D1) are specified for each size.
  • Screws: DIN 912 V4A 80 screws are used, with specific tightening torques for stainless steel and steel.
  • Tightening Torque: Varies by material and size, with values provided in Newton-meters (Nm).
  • Number of Screws: Each coupling uses 8 screws.
  • Nominal Torque: Provided for both stainless steel and steel, with values in Nm.
  • Weight: Specified for each size in grams.
  • Optional Features: Keyway according to DIN 6885 available upon request, with a rotational speed of 4000 RPM.

Key Data Summary
  • Both types of couplings are available in sizes ranging from 29 mm to 85 mm.
  • The tightening torque for screws varies significantly between stainless steel and steel, with higher values for steel.
  • Nominal torque values are higher for steel compared to stainless steel, indicating a greater load capacity.
  • Weight increases with size, impacting the choice based on application requirements.
