STK Catalog

Product catalog summary

Overview: The document provides detailed specifications and information about STK rigid couplings, which are designed for high torque and zero backlash applications. These couplings are suitable for use with servomotors and induction motors in various industrial applications such as machine tools, semiconductor manufacturing equipment, printing presses, and packing machines.

Specifications:

Max. rated torque: 1900 N∙m
Bore ranges: φ6 to 50 mm
Operating temperature: -40°C to 175°C

Materials and Structure:

Hub material: Black-oxided steel alloy or stainless steel
Hexagon head screw material: Alloy steel or stainless steel
Surface finishing: Black coating

Models and Variants: The document lists various models of STK couplings, including sliced and split types, with specifications for maximum torque, tightening torque of screws, and mass. The models range from STK-6 to STK-80, with varying dimensions and material options.

Dimensions: Detailed dimensions are provided for each model, including diameter, length, and screw specifications. The document notes that for larger sliced couplings, the slit is on the outside.

Usage Recommendations: To achieve maximum torque values, proper use is essential, including material and dimensional accuracy of the shaft (recommendation h9) and ensuring it is free of grease. Maximum RPM depends on material and size.

Rigid Couplings yjjg High stiffness Riged Couplings for High Torque and Zero Backlash With exactly aligned shafts, an offset compensation is not necessary, here the rigid coupling or shell coupling is the right solution. This type of coupling is characterized by highest torques and particularly high torsional rigidity. Another plus is the ease of installation.
