Weima Electric (Shanghai) Ltd.

• Compact, highly reliable and fully self-contained design.

• Robust casing design.

• High capacity radial and axial load capability.

• 2 frame sizes covering a shaft diameter range of 300-500mm.

• Radial loads are supported on a spherically seated whitemetal lined journal bush which is supplied in halves.

• High pressure oil injection can be incorporated in the journal bush if required.

• Tilting whitemetal thrust pads or whitemetal location faces can be incorporated at each end of the journal bush to support axial loads.

• Design can include offset pivoted tilting thrust pads in order to reduce oil film temperatures and maximise film thicknesses.

• Centre pivoted thrust pads can be fitted when continuous bi-directional operation is a requirement.

• High pressure oil injection can be incorporated in the thrust faces if required.

• PTFE thrust pads can be incorporated in the thrust faces to increase the thrust capacity and reduce the bearing frame size.

• Oil circulation is achieved using an oil ring which is supplied in halves and clamped to the shaft working in conjunction with a floating oil scraper in the casing top.

• Available with water cooling or circulating oil cooling.

• Integral cooler assemblies can be supplied in cupro-nickel, stainless steel or titanium.

• Electrical insulation can be provided.

• Labyrinth end baffles, which are supplied in halves, are included at each end of the bearing.

• Sealing to various IP grades can be provided at each end of the bearing as required.

• Easy to install and maintain.

• Design can accommodate a wide variety of instrumentation requirements.
