The coupling TNZ ZCA-BT consists of two coupling halves with a brake drum mounted in between, and has longer fitted bolts than the model TNZ ZCA. TNZ ZCB-BT: Double engagement design with a bolt-on O-ring carrier and a brake drum The coupling TNZ ZCB-BT consists of two coupling halves with a brake drum mounted in between, and has longer fitted bolts than the model TNZ ZCB.

The model TNZ ZCAF is composed from the coupling halves of the coupling TNZ ZCA and is complemented by an intermediate shaft and two rigid counter-flanges. If required, the torsional stiffness of the shaft can be tuned to the dynamic behavior of the drive line. In addition, the intermediate shaft, which serves to accommodate longer shaft separations, can be mounted and dismounted radially without having to move the connected machines. TNZ ZCBF: Double engagement design with a bolt-on O-ring carrier for ease of installation, and an intermediate shaft to fulfill specific requirements in terms of torsion spring stiffnesses The model TNZ ZCBF is composed from the coupling halves of the coupling TNZ ZCB and is complemented by an intermediate shaft and two rigid counter-flanges. If required, the torsional stiffness of the shaft can be tuned to the dynamic behavior of the drive line. In addition, the intermediate shaft, which serves to accommodate longer shaft separations, can be mounted and

The model TNZ ZCAK is a TNZ ZCA coupling with limited end float. The limitation of the end float serves to axially locate a shaft that is mounted on sleeve bearings. The rotor of an electric motor with sleeve bearings can thus be aligned within a desired tolerance range via the coupling to the bearing of the driven machine so that the rotor remains at its magnetic centre during acceleration of the driving machine. The limitation of the end float constrains the ability to compensate for angular and radial shaft misalignments.

Compared to the TNZ ZCA types, the coupling model TNZ ZCAU is equipped with an elongated hub, the length of which can be adapted to the plant requirements. TNZ ZCBU: Double engagement design with a bolt-on O-ring carrier for ease of installation and an elongated universal hub Compared to the model TNZ ZCAU, the TNZ ZCBU coupling is equipped with an O-ring carrier which facilitates installation by changing the mounting sequence. For mounting the coupling, unscrew the cover and place it on the shaft. Mount the hub onto the shaft, slide the sleeve onto the hub and fasten the O-ring carrier to the sleeve. This way of mounting is advantageous when large couplings are involved. Like the model ZCAU, the ZCBU has an elongated hub the length of which can be adapted to the plant requirements.

Unlike the model TNZ ZCAUU, the coupling TNZ ZCA has two elongated hubs the length of which can be adapted to the plant requirements.

The coupling model TNZ ZCAV is suitable for vertical installation. To this purpose, the TNZ ZCA is equipped with supporting plates which hold the sleeves in their vertical position. TNZ ZCBV: Double engagement design with a bolt-on O-ring carrier and a supporting plate for vertical installation The coupling model TNZ ZCBV is suitable for vertical installation. To this purpose, the TNZ ZCB is equipped with supporting plates which hold the sleeves in their vertical position.

The coupling model TNZ ZCAZ is complemented with a spacer that is mounted between the sleeves of a TNZ ZCA coupling by using fitted bolts. The spacer serves to accommodate larger distances between the shafts ends, and can be mounted and dismounted radially without having to move the connected machines. TNZ ZCBZ: Double engagement design with a bolt-on O-ring carrier for ease of installation, and a spacer to accommodate larger shaft separations Unlike the TNZ ZCAZ, the coupling model TNZ ZCBZ is equipped with a bolt-on O-ring carrier which facilitates installation by changing the mounting sequence.
