RENK Centrally flange-mounted bearing type EM

Slide bearings have lower noise levels in comparison to rolling bearings and are resistant to loads caused by shocks thanks to lower material stresses
 
Slide bearings: 
• are maintenance-free or low-maintenance and easy to install
 
• have a lubricant film that dampens vibrations, impacts, and noise
 
• are resistant to dust penetration and shocks
 
• require a small radial installation space and are structurally adaptable (can be integrated as component)
 
• are suitable for very high speeds
 
• exhibit practically no wear during fully hydrodynamic continuous operation and with hydrostatic bearings
 
• are most cost-effective than rolling bearings at large dimensions

Additional Information

Bearing Housing
 
The finned EM-type housings are made from a high-quality cast iron (EN-GJL-300) and are designed for heavy duty performance. Other materials such as, for instance, nodular cast iron EN-GJS-400-15 or cast steel GS 45 can be supplied by special arrangement. Tapped holes for thermometer, oil inlet and outlet, oil sight glass, thermometer in the oil sump or suction line of a circulating pump are available on either side. For special cases (e. g. fitting of oil coolers or vibration detectors) finish
machined housings are taken from stock and provided with additional connection
holes.
 
Bearing Shell
 
The shells are spherically seated in the housing. They consist of a supporting steel body lined with lead based RENKmetal therm V6 or therm 89. Both design and manufacture are in accordance with the highest standards required in heavy engineering: troublefree assembly and long life even under severe operating conditions.
