Shrink Discs RLK 608

Product catalog summary

Shrink Discs RLK 608 Overview

Design and Features:
The RLK 608 shrink discs are designed with a two-part structure, offering the highest torque capacity. They can transmit torque ranging from 330 Nm to 4,225,000 Nm. The assembly is straightforward and quick, requiring only the tightening of clamping screws without a torque wrench. The enclosed design makes them impervious to dirt, ensuring true running even at high speeds. They are suitable for hollow shafts or hubs with outer diameters from 30 mm to 620 mm.

Application Example:
The RLK 608 shrink discs provide a backlash-free connection between a hollow-shaft gearbox and a machine shaft, reducing the risk of fretting corrosion and allowing for easy disassembly after long periods of operation.

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. Technical details are available on page 31.

Ordering Example:
For a hollow shaft with an outer diameter of 155 mm, the shrink disc RLK 608-155 can be ordered using article number 4200-155801-000000.

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 ≥ 360 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 Specifications:
The document includes detailed tables listing dimensions, technical data, and article numbers for various sizes of shrink discs. These tables specify transmissible torque or axial force, clamping screws, and weight for each size.

Note:
The shaft diameters listed are examples, and other diameters can be used as per technical specifications on page 31.
