DESCRIPTION OF THE DESIGN The Zollern Z type of horizontal bearings are designed acc. to different DIN and ISO specifications for a wide range of heavy duty applications (electrical machines, fans and blowers, turbines and test rigs). The modular system applies for the different types of bearings (pedestal, end flange and centre flange), i.e. the combination of different modules of this modular system is always possible. This has resulted in simple assembly and elimination of mistakes during installation, commissioning and maintenance procedures due to the positioning of screws and pins....

4 5 Oil supply Electrical insulation Fully self contained lubrication is achieved from a loose oil ring. Alternatively, where bearings are lubricated by an external oil circulation system, this loose oil ring can be used to permit emergency shutdown without damage if a system failure occurs. Z-bearings can be used for marine applications by using an oil ring guide to cater for vessel motions. To prevent stray currents conducted by the shaft Z-bearings can be supplied electrically insulated as an option. In this case the spherical seat of the housing is coated with a wear-resistant and...
