If these chains are to be usedin environments where they are submerged in or come incontact with water, they must be pre-lubed. If chains areused in these conditions without lubrication, poor articulationof the chain may occur at a much earlier stage thanexpected.Offset PinLength LMaximumAllowable LoadkN{kf}ApproximateMassk/m0.12 {12} 0.14 1600.26 {27} 0.33 3200.44 {45} 0.64 2400.69 {70} 1.04 1921.03{105} 1.53 1601.77{180} 2.66 120Connecting linkRS40-AS-1 to RS60-AS-1: Clip-typeRS80-AS-1: Cotter pin-typeOffset PinLength LMaximumAllowable LoadkN{kf}ApproximateMassk/mLinksPerUnitLinksPerUnit0.69{70} 0.64 240RS50-AS-1 15.875 10.16 9.53 2.0 15.0 13.0 5.09 22.3 10.3 12.0 23.9RS60-AS-1 19.05 11.91 12.70 2.4 18.1 15.6 5.96 27.6 12.85 14.75 29.4RS80-AS-1 25.40 15.88 15.88 3.2 24.1 20.8 7.94 35.7 16.25 19.45 39.01.03{105} 1.04 1921.57{160} 1.53 1602.65{270} 2.66 120103
