Miba Industrial Bearings Miba Industrial Bearings is one of the largest international hydrodynamic bearing supplier for turbomachinery. Our roots date back over 100 years when the German site first started producing bearings. Equipped with this experience we are now a center of excellence in bearing design, repair, troubleshooting and analysis as well as reversed engineering solutions. The selection of a Miba Industrial bearing offers numerous benefits: • A worldwide Miba Group with contacts in Europe, Americas and Asia is focused on customer support, competitive lead times and highest...

Anti-rotation pin The anti-rotation pin defines the bearing orientation angle and secures the bearing against rotation. By standard two anti-rotation pin positions are existing, each at an angle of 18° from the bearing split line. For typical load directions from gearings one position leads to a load between pads orientation (LBP) and the other to a load on pad (LOP) orientation. Individual positions of the antirotation pin are possible upon request. Insulation All bearings can be insulated by adding special plates, insulation material or coatings, (depending on the application) to isolate...

Lubrication The various Miba bearing models contain two main types of oil supply: Directed lubrication: Oil inlet nozzles control the flow. Directed lubrication reduces the power loss and leads to lower pad temperatures. The end plate design is open (non-sealing) for the cavity evacuation. As an addition, if requested, direct lubrication with a pad oil distribution feature at the pad inlet can be provided. Flooded lubrication: • Option 1: Equipped with lateral floating seals, rate of oil flow controlled by outlet orifices. • Option 2: Laterally sealed by throttle rings with a defined gap to...

Eddy Grooves Steel – White metal 16MnCr5 steel with a high-quality white metal (Tegostar®) is the standard material combination for the tilting pads. For reducing maximum bearing temperatures, Miba developed the patent pending eddy grooves. The grooves create radial flow components in the fluid film at the high load area of the bearing, where normally full laminar flow exists. The material combination offers a high bonding strength (according to ISO 4186-2 / Chalmers Test) and mechanical properties which clearly exceed the demand of even highly loaded bearings. These flow components act as...

Power loss / Oil supply charts: • Calculation based on DIN 31657; Oil type: VG32 @ 50 °C; directed lubrication; Center pivot; ΔT ≈ 21 K. • Offset pivot pads show reduced temperatures with an approximately 15% increased rate of oil flow. • For ISO VG 46 power loss and oil flow are approximately 20% higher. • Calculations for divergent parameters on request.  Power loss / Oil supply charts: • Calculation based on DIN 31657; Oil type: VG32 @ 50 °C; directed lubrication; Center pivot; ΔT ≈ 21 K. • Offset pivot pads show reduced temperatures with an approximately 15% increased rate of oil flow....

Bearing Repair, Service and Upgrade Damage to bearings generally results in machine failure and thus in costly downtimes. This is why Miba has expanded the area of bearing repair, in addition to the specialization in the development and manufacturing of new bearings. We help customers to increase efficiency and lower costs by upgrading or reengineering old bearings. • Bearing failure analysis • Bearing design optimization • Bearing repair • Reverse engineering Starting with an evaluation of the existing bearing, we • Training can recommend the best solution and realize the repair ^ On s^e...

Simulation & Analysis Test Stands With available professional software we are able to simulate the bearing operation and visualize the flow, deformation or stress behavior. Therefore, we can analyze and further develop our product design. These tools are an indispensable addition to our test stands to guarantee you the best technical solution. Since 2013, two bearing test benches for radial bearings have been in heavy use for conducting experiments and trial series to improve performance, efficiency and operational safety. With regard to bearing performance, the test rigs allow...
