RLK 603 series

Product catalog summary

Shrink Discs RLK 603 Overview

Design and Features:
The Shrink Discs RLK 603 are designed with a three-part structure, offering high torque capacity. They can transmit torque ranging from 25 Nm to 1,460,000 Nm. The clamping screws are tightened using a torque wrench, and the design allows for easy disassembly without the need for jacking screws. These discs are suitable for hollow shafts or hubs with outer diameters between 14 mm and 500 mm.

Application Example:
An example application is the backlash-free connection of a cardan shaft flange to a machine shaft using the Shrink Disc RLK 603. This connection minimizes the risk of fretting corrosion, facilitating easy disassembly even after prolonged use.

Simultaneous Transmission:
The transmissible torques and axial forces are specified for cases where either torque or axial force is zero. When both are transmitted simultaneously, their values are reduced. Detailed technical points are available on page 31.

Ordering Information:
For ordering, specify the Shrink Disc RLK 603 for the required hollow shaft diameter, e.g., RLK 603-100 for a 100 mm diameter. The article number is 4200-100301-000000.

Surface and Material Requirements:
The average surface roughness at contact surfaces should be Rz = 10 to 25 µm. The shaft and hollow shaft should have a yield strength of Re ≥ 340 N/mm² and an E-module of approximately 206 kN/mm².

Installation:
Installation and operating instructions are available upon request. The transmissible torques or axial forces are subject to specific tolerances, surface characteristics, and material requirements.

Technical Data and Dimensions:
The document provides detailed tables listing dimensions, technical data, and article numbers for various sizes of Shrink Discs. These include transmissible torque or axial force, clamping screw specifications, and weight.

Note:
The shaft diameters listed are examples, and other diameters can be found in the technical specifications on page 31.
