DIN Standard Bearing

DIN standard Bearings DIN standard Bearings along with it's suitable Housings together and other required accessories makes a complete assembly. Basically there are three types of standard assemblies, which are available according to their applications.

• 31690 - Pedestal Mounted Housing Assembly
• 31693 - End Shield Mounted Housing Assembly
• 31694 - Middle Flange Mounted Housing Assembly. (Detailed catalogue is available)
• Bearing housings

  Depending on the operating conditions, the bearing housings are supplied either with fins or as a smooth design.(Flange bearings are finned design only.) In standard Bearing Housings are available with high-rigidity Grey cast iron (IS 210) or specification can be modified as per customer requirements. Housings are positioned with Inlet, Outlet, Shell & Sump thermometer entry andother positions can also be made as per customer requirements.

  Bearing shells

  The bearing shells are spherically seated in the housing .This means simple assembly as well as suitability for high static and also dynamic axial and radial loads. Forged bearing shells with white metal lining (min 3mm.) have sufficient hold for different applications. Modular assembly system includes axial design B, K and A (with R.D pad) type. Usually bearing shells can with cylindrical or two- lobe be fitted with loose oil rings. The perfect metallic bond between steel and bearing metal is guaranteed by the specified ultrasonic tests which are carried out in the course of manufacturing.

  Seals

  Floating labyrinth seals are sufficient to achieve by using additional labyrinth for most of the applicationsandRigid seals are also available for Special application. Seals are also available on basis of requirement of high oil throughput. The assembly is sealed with an end of Protection Class IP 44, IP 55 and IP56 etc all the seals are designed in such a way that it helps to achieve the optimum Bearing Performance.

  Lubrication

  The loose oil ring normally provides a sufficient oil supply subjected to verification of operating temperature being within limit. However, the bearings are always set up to an oil supply system. The oil ring ensures emergency lubrication in the event of a malfunction of the supply system.

  Insulation

  The bearings also can be insulated to prevent shaft currents. In an insulated bearing all contacts of housing with shaft or bearing bush is made through insulated component such as guide pin bush, seal carrier bolts and Nylon bush.

  Heat Dissipation

  Heat generated in the bearing is usually dissipated through radiation and convection. Greater dissipation can be achieved by fitting an oil cooler in sump or connecting the system with an oil supply.

  Temperature Monitoring

  Both lateral surfaces of the bearing can be equipped with connections to measure the temperature. Identical and interchangeable provisions have been made to accommodate temperature detector, one each from each side for oil sump and bearing bush.

  Shaft Details

  Recommended shaft details are provided with the GA Drawing after PO. The journal bearing dia and required shaft tolerance are further calculated on the basis the outputs of Hydrodynamic Bearing calculations. Any deviation from the recommended shaft diaand tolerance to be informed to us for further check.
