Be sure toindicate that the bellows is required when ordering the LM Guide.Model number codingSt1LmaxLminTS1Wt2H1Models NR/NRS 25X to 45S1Wt3t2H1Models NR/NRS 55 to 100Main dimensionsModelA SupportedMounting bolt bmodelNo.LmaxA,LA Lmin numbersW H H1 P b1 t1 t2 t3 S S1 B,LB T25 48 25.5 25.5 10 26.6 4.6 13 — M35l M44l 11 1.5 7 25X30 60 31 31 14 34 5.5 17 — M48l M44l 15 1.5 9 3035 70 35 35 15 36 6 20.5 — M48l M54l 15 2 10 3545 86 40.5 40.5 17 47 6.5 24 — M510l M54l 17 2 10 45NR/JN 55 100 49 49 20 54 10 29.5 18 M510l M54l 20 2 13 55NRS65 126 57.5 57.5 20 64 13.5 36.2 20 M612l M65l 22 3.2 13 6575 145 64 64 30 80 10.5 34.2 26 M612l M65l 25 3.2 20 7585 156 70.5 70.5 30 110 15.5 39.5 28 M612l M65l 39.5 3.2 20 85100 200 82 82 30 140 15 40 34 M816l M65l 30 3.2 20 100JN25 - 60/420Model number ofbellows for NR/NRS25XDimensions of the bellows(length when compressed/ length when extended)TableNote) The length of the bellowsis calculated as follow.SLmin S: Stroke length (mm)A– 1Lmax Lmin•AA: Extension rateTelescopic coverBellowsLM Guide (Options)Industrial TechnologiesBaseFig.2 Example of Mounting the BellowsB1-255
