RLK 350 series

Product catalog summary

Overview: The document provides technical specifications and application details for Cone Clamping Elements RLK 350, designed to center hubs to shafts, particularly for small shaft diameters ranging from 5 mm to 50 mm. These elements are used for backlash-free connections, such as sprocket wheels in industrial door drives.

Features:

Centers the hub to the shaft.
Transmissible torque ranges from 7.2 Nm to 2,200 Nm.
Suitable for shaft diameters between 5 mm and 50 mm.

Application Example: The RLK 350 is used for connecting sprocket wheels to shafts in industrial door drives, allowing easy alignment in axial and circumferential directions during assembly.

Simultaneous Transmission: The document notes that transmissible torques and axial forces are reduced when both are transmitted simultaneously. Technical details are provided on pages 74 and 75.

Ordering Example: For a shaft diameter of 50 mm, the order would be RLK 350, size 50 x 80, with article number 4208-050001-000000.

Materials: The shaft and hub require an E-module of ≥ 170 kN/mm².

Installation: If the hub cannot move freely, values for torque (M), force (F), and pressures (PW and PN) are reduced by 37%. Installation instructions are available upon request.

Tolerances and Surfaces:

Tolerances: h8 for shaft diameter, H8 for hub bore.
Surface roughness: Rz = 10 to 25 µm at contact surfaces.

Technical Data: The document includes a detailed table of dimensions, technical data, and article numbers for various sizes of the RLK 350, specifying parameters such as yield strength, transmissible torque or axial force, contact pressure, clamping screws, and weight.
