R+L Hydraulics has released its LF torsional coupling series for demanding applications in agricultural and construction machinery, fans, compressors, high-pressure pumps, wind turbines and marine industries.
The basic component of the LF torsional coupling is a versatile rubber element, which is available in various materials for different types of resistance and torsional stiffness. Oil, heat and corrosion-resistant materials such as Hytrel and Zytel are also available. The design means that the LF torsional coupling compensates well in terms of misalignment and absorbing vibrations and shock loads.
The company says that installation is straightforward as the element is bolted to a cylindrical hub with radial screws and then attached to a flange hub with axial screws.
The couplings do not need lubrication and are maintenance-free. The air flow design cools the components during operation. They are designed for tight spaces in machine housings or for use from shaft to shaft. They do not require any special connectors, tools or time-consuming assembly procedures.
LF torsional couplings are available with bore dimensions from 8 mm to 130 mm.
