This bolt coupling is a rigid shaft coupling. It is made of two halves, which are cast iron grade GG25 connected by means of bolts. It is maintenance and lubrication free. Additionally, its construction prevents fretting corrosion and allows for easy mounting and dismounting. The bolt coupling is designed to connect horizontal shafts with similar diameters.

The indicated torque values in the table on on page 11 refer to couplings without keyways. To transmit higher torques it is possible to machine keyways by following DIN 6885/1. The values of the torque have been calculated with a coefficient of friction equal to 0.15 and with a screw tightening torque according to the indicated value (DIN912 - 8.8).

Keyed Sleeve Coupling
The sleeve coupling is the most straight forward type of rigid coupling, also know as a ‘muff’ coupling. It is a machined cylinder that joins two shafts, usually a drive shaft and a driven shaft, used when two shafts are well aligned with little or no misalignment. Due to the coupling keyway and spline key causing concentration of torque on the one point of the coupling this setup is not used for high speed or high torque applications. One or both shafts require being able to be moved along the axis of the shafts in order to install the coupling.

Splined Sleeve Coupling
The spline coupling distributes the torque around the circumference of the coupling by way of the multiple spline grooves in conjunction with the splines on the shaft making these type of sleeve couplings better suited to higher speeds and torque applications.

Flange Coupling
Two separate flange hubs with a keyed fit to the individual shaft. These two flanges will be joined together via a set of bolts. One flange with a projected pilot or spigot and the other flange will have a corresponding recess to facilitate good alignment of the flanges. Generally used for larger shafts and heavier loads.
