Thrust Bearings Series D For Absorbtion Of High Axial And Radial Loads Thrust Bearings Type DG/DR RENK thrust bearings type DG/DR will absorb high axial and radial loads, even shockloads, irrespective of the sense of rotation. The main feature of the bearings series D are the RS/RD thrust pads with circular working surfaces, as fully tested and proven in service in numerous applications for well over 25 years. The bearings type DR are available with natural cooling, water cooling or oil circulation lubrication, the bearings type DG are available with external oil supply only. Housings are normally of a saddletype (with support near the split line). A pedestal type of housing is also available on request (see also separate catalogue „Thrust Bearings Type DN“ RH-1073)

Technical Information This publication contains all the relevant information that is needed when considering the use of thrust bearings (shaft range 180 to 600 mm diameter) for propeller shafts, turbines and pumps. Bearing Housing The strong housing of the thrust bearing sizes 16 to 56 is made from a high quality cast iron (EN-GJL-300). Alternative materials, such as nodular cast iron (EN-GJS-400-18-LT), can be supplied in special cases. Radial Part The radial part is normally designed as two bearing shells, in halves and has a plain cylindrical seating in the housing. The use of two shells offers...

1) Sizes 63, 71 and 80 upon request.

Load Table The table serves only to select the size of DG/DR-Type bearing. Before booking an order, however, it will be necessary to carry out an EDP calculation, taking into account the reciprocal influence of operating parameters. (1) Radial loads FR in [kN] as permanent load (maximum value) for plain cylindrical bore without hydrostatic jacking. (2) Radial loads FR in [kN] as permanent load (maximum value) for plain cylindrical bore with hydrostatic jacking. (3) Axial load FA [kN] as maximum admissible load at start-up. During operation, this load can be increased by approx. 60%. The values...
