13 High Performance Live Centres S Series Types SV, SVG Centrepoint 60° full carbide with safety core sa•co® Regrindable to the braze line Runout Type SV max. 0.005 mm Type SVG max. 0.003 mm with test report Application Same as type SH, SHG. The point angle of 60° up to the large diameter can be utilised for loading workpieces. For cylindrical grinding operations we recommend the use of our supplementary seal (fig. on page 10) A safety core is integrated in the carbide point of types SV, SVG. If the interface of carbide and basic material becomes overstressed, e.g. through operating error or mishandling, the safety core prevents the carbide with the loaded component from slipping. Thus high consequential damage is avoided. aco saco safety core from BRUCKNER ® s 50 40 100 200 300 5000 400 500 1000 2000 3000 4000 10000 300 40 50 100 200 500 400 1000 2000 4000 3000 5000 10000 1000 40 50 100 200 300 400 500 3000 2000 5000 4000 10000 Axialbelastung daN Drehzahl 1/min Drehzahl 1/min 10000 5000 4000 3000 2000 1000 500 400 300 200 100 50 40 200 20 25 100 50 150 250 500 1000 2000 1500 2500 5000 Radialbelastung daN Werkstückgewicht daN 2 1 3 RV AV 3 1 4 2 4 50 40 100 200 300 5000 400 500 1000 2000 3000 4000 10000 300 40 50 100 200 500 400 1000 2000 4000 3000 5000 10000 1000 40 50 100 200 300 400 500 3000 2000 5000 4000 10000 Axialbelastung daN Drehzahl 1/min Drehzahl 1/min 10000 5000 4000 3000 2000 1000 500 400 300 200 100 50 40 200 20 25 100 50 150 250 500 1000 2000 1500 2500 5000 Radialbelastung daN Werkstückgewicht daN 2 1 3 RV AV 3 1 4 2 4 Radial and axial loads for a bearing life of 2000 operating hours (calculation example on page 11) Radial – Types SV, SVG Axial – Types SV, SVG r.p.m. r.p.m. workpiece weight daN radial load daN axial load daN LA LB LC DG D braze line Type SV ID.No. 5242ZV20 5243ZV20 5246ZV25 5244ZV25 5247ZV35 5245ZV45 Type SVG ID.No. 5252ZV20 5253ZV20 5256ZV25 5254ZV25 5257ZV35 5255ZV45 Morse taper 2 3 3 4 4 5 D 20 20 25 25 35 45 DG 45 45 58 58 76 95 LA 24 24 34 34 43 59 LB 52 52 58 58 68 89 LC 82 83 99 101 120 159 Workpiece weight max. daN* 100 100 250 250 400 600 r.p.m. max.* 5500 5500 5000 5000 4000 3500 Radial/axial load graph RV1/AV1 RV1/AV1 RV2/AV2 RV2/AV2 RV3/AV3 RV4/AV4 Supplementary seal ID.No. V20 V20 V25 V25 V35 V45 *observe the load graphs
