1 We keep the presses rolling OBU - Oscillating Bearing Unit Units for inking- and dampening rollers (oscillating rollers)

2 We keep the presses rolling Oscillating bearing: Current design Current solution: cylindrical roller bearing with wider innerring

3 We keep the presses rolling Oscillating bearing: Recommended Product Range ) = permissible axial displacement from normal position - oscillating bearings have normally a polyamidcage, except BC the standard radial clearance is bigger than normal (C3) - oil and grease lubrication are possible - other sizes then in the table above on request Designationd [mm] D [mm] C AR [mm] B [mm] C [kN] C 0 [kN] s 1 [mm] BC ,523,821,6  22 BC ,126  30 BC ,652  12,5 BC ,652  17,5 BC ,295  13 BC ,295  17,5 BC ,295  20

4 We keep the presses rolling sealed unit, based of cylindrical roller bearing, without shaft Components: housing cover bearing sealings grease sensor (opt.) Oscillating Bearing Unit OBU: Concept 1 operator side

5 We keep the presses rolling sealed unit, based of cylindrical roller bearing, with shaft interface to the oscillating roller: flange, coupling or other linking Components: housing shaft cover bearing sealings grease sensor (opt.) Oscillating Bearing Unit OBU: Concept 2 operator side

6 We keep the presses rolling Oscillating Bearing Unit OBU: Sealing depends on: the influences from outside of the unit available space within the design the requirements of the customers the chosen kind of lubrication possible sealings:  presealing  gapsealing (f.e. gap-, chamber-, labyrinthsealing)  recommendation SKF: - gapsealing (- or, if necessary, a combination of preseal- and gapsealing)

7 We keep the presses rolling Oscillating Bearing Unit OBU: Lubrication kind of lubrication depends on: requirements of the customers the environmental conditions possible kinds of lubrications:  long time grease lubrication (specially tested by SKF)  continuously grease lubrication  oil circulation or oil bath lubrication  recommendation SKF: long time grease lubrication

8 We keep the presses rolling Oscillating Bearing Unit OBU: Advantages of long time grease lubrication  long relubrication intervalls (3-5 years)  specific balancing between grease, amount of grease and sealing  application fits in the concept "oilfree press"  no oil-leakages  less oilpipes are needed  no need of central grease lubrication system

9 We keep the presses rolling  complete unit, ready to mount  easy integration in mounting procedure  time consuming mounting at the press producer is not longer necessary  no risk of contamination during mounting  longtime grease lubrication  one article code, i.e. less numbers of single positions  easier handling, disposition, management of inventory stocks  reducing total costs Oscillating bearing unit OBU: Benefits

10 We keep the presses rolling Oscillating Bearing Unit OBU: Customer Requirements  for life lubrication (  longtime grease lubrication)  reducing costs ( )  easy and plain mounting ( )  benefits for enduser ( - longtime grease lubrication, numbers of spare parts)  references (  tests with oscillating bearing unit within SKF; oscillating bearings are in the field since 10 years)  longtime usage/high quality ( )  environmental friendly ( )  one contact person ( )  easily handling/logistics ( )  new ideas ( )

11 We keep the presses rolling Oscillating Bearing Unit OBUs: Arrangement 1 - oscillating bearing unit without shaft - OBU for operator side OBU for drive side (oil from outside)

12 We keep the presses rolling Oscillating Bearing Unit OBUs: Arrangement 2 - oscillating bearing unit with shaft, for splited cylinder - OBU for operator side OBU for drive side (oil from outside)

13 We keep the presses rolling Oscillating Bearing Unit OBUs: Arrangement 3 OBU for operator side OBU for drive side [splited cylinder] external oscillator oscillating bearing unit with shaft drive (external oscillator) [splited cylinder] Advantages of arrangement 3:  easy handling of interfaces  all parts out of one hand  easily inclusion in whole process (samples/tests/series)

14 We keep the presses rolling Oscillating Bearing Unit OBUs: Arrangement 3 external oscillators of Scandrive variable stroke fixe stroke
