DRadius rChMTwo SetScrews (SS)120° ApartSILVER-LUBE ®BEARING INSERTSThe grease in this product is an aluminium complex food grade grease.In the event of relubricating being necessary, this type of grease is thefirst choice replacement. Please note that Silver-Lube ® bearings werepreviously charged with Chevron Poly FM2 grease, which isincompatible with the current aluminium complex food grade grease.Original Chevron greased inserts can be identified by there being onlythree markings on the flinger, for example: ‘RHP JAPAN J1025-25GCR’. Inserts charged with an aluminium complex food gradegrease can be identified by the presence of an additional letterbetween RHP and Japan; for example Kyodo Yushi-greased insertswere marked with a ‘K’ to give ‘RHP K JAPAN J1025-25GCR’.If an aluminium complex food grade grease is not available, it isessential that any alternative grease is USDA H1 approved and ideallychemically compatible with the original grease. If chemicalcompatibility cannot be assured, then it is recommended that theoriginal grease is completely flushed out from the system beforerelubrication. NSK should be consulted if necessary.SS1BINSERT DESIGNATIONS, DIMENSIONS AND WEIGHTSTable 13RHPWEIGHTDESIGNATION BORE DIA D C B S S1 r h M SS Cr (N) Cor (N) (kg)J1020-20GCR 20 47 16 31.0 12.7 18.3 1.5 4.0 5.0 M6 9910 5350 0.16J1020-3/4GCR 3/4" 47 16 31.0 12.7 18.3 1.5 4.0 5.0 M6 9910 5350 0.16J1025-25GCR 25 52 17 34.0 14.3 19.7 1.5 3.5 5.5 M6 10820 6300 0.20J1025-1GCR 1" 52 17 34.0 14.3 19.7 1.0 3.5 5.5 M6 10820 6300 0.20J1030-30GCR 30 62 19 38.1 15.9 22.2 1.5 4.5 6.0 M6 15000 9050 0.32J1030-1.3/16GCR 1.3/16" 62 19 38.1 15.9 22.2 1.0 4.5 6.0 M6 15000 9050 0.32J1030-1.1/4GCR 1.1/4" 62 19 38.1 15.9 22.2 1.0 4.5 6.0 M6 15000 9050 0.32J1035-35GCR 35 72 20 42.9 17.5 25.4 2.0 4.5 6.5 M8 19820 12300 0.48J1035-1.1/4GCR 1.1/4" 72 20 42.9 17.5 25.4 2.0 4.5 6.5 M8 19820 12300 0.48J1035-1.7/16GCR 1.7/16" 72 20 42.9 17.5 25.4 1.5 4.5 6.5 M8 19820 12300 0.48J1040-40GCR 40 80 21 49.2 19.0 30.2 2.0 4.5 8.0 M8 22540 14300 0.64J1040-1.1/2GCR 1.1/2" 80 21 49.2 19.0 30.2 2.0 4.5 8.0 M8 22540 14300 0.64All dimensions in mm except inch bores.
