(Note that the new AGMA specification requires a FZG result >12 load stages butdoes not include Timken, Four Ball Wear and Four Ball Weld performance, as previouslyrequired in the US Steel No. 224 specification that is shown for reference.)The data also show that 0.3% <strong>NA</strong>-<strong>LUBE</strong> AW-6310 can be added to an R&O oil containing0.7% <strong>NA</strong>-<strong>LUBE</strong> BL-1208 to meet the AGMA 9005-E02 Industrial Gear Oil Specification,however, this blend does not show as good EP performance as the <strong>NA</strong>-<strong>LUBE</strong> BL-1208/KX1236 blend, as noted using the Four Ball Weld test. <strong>NA</strong>-<strong>LUBE</strong> BL-1208 Performance In Industrial Gear OilsTESTSADDITIVESISO VG 2200.30% BL-12081.10% KX1236Mineral Oil0.30% BL-12081.10% KX123680% PAO 40 cSt10% PAO 8 cSt10% DIDA*0.70% BL-12080.30% AW-6310Mineral OilAGMA 9005-E02Industrial Gear Oil EPSpecificationMineral OilFour Ball Wear (ASTM D 4172)40 kgf, 1200 rpm, 75ºC, 1 hour (mm)40 kgf, 1800 rpm, 75ºC, 1 hour (mm)30 kgf, 1800 rpm, 75ºC, 1 hour (mm)20 kgf, 1800 rpm, 75ºC, 1 hour (mm)0.580.570.490.440.530.510.430.290.42------US Steel No. 2240.35 maxFour Ball Weld (ASTM D 2783)10 seconds, 1800 rpm, 25ºCOK Load (kgf)Weld Load (kgf)240260280300160180US Steel No. 224250 kgf min
