They absorb most of the kinetic energy developing on impact. They act as dampers and prevent damaging shock and rebound. They also act as sound dampers. The parabolic shape of these buffers generates progressive resilience characteristics: impact and shock effects are absorbed gentler. see also... • Rubber Buffers GN 351 / GN 451 → Page 1524 • Buffers GN 352 / GN 452 → Page 1531 • Mounting Blocks GN 412.1 → Page 956 Information • Natural rubber (NR) - - Black - - Vulcanized to the cover plates - - Temperature resistant up to 80 °C - - Hardness Shore A ±5 Soft * 40 Medium 55 Hard * 70 • Cover plates, threaded bushings, threaded studs Stainless steel AISI 304 • Elastomer Characteristics → Page 2158 • Stainless Steel Characteristics → Page 2166 • RoHS Specification 5 • Rubber in gray On request * not available from stock, requires a minimum order quantity 1 2 3 d 1 h d 2 Length l s t Spring rate ≈ in N/mm Max. load in N Max travel ≈ in mm Hard- ness 40 Hard- ness 55 Hard- ness 70 Hard- ness 40 Hard- ness 55 Hard- ness 70 10 10 M  5 12 1,2  5 14  20 40  46  59 113 3 20 15 M  6 18 2    6 30  49 78 130 195 320 4 20 24 M  6 18 2    6 14  22   55  82 130 330 6 25 20 M  6 18 2    6 16  38 96  84 190 495 5 30 30 M  8 18 2    8 25  35   84 190 260 630 7,5 30 36 M  8 20 2    8 20  36 72 180 320 650 9 35 40 M  8 23 2    8 26  30   63 260 300 630 10 50 50 M 10 28 2    8 54  78 90 675 970 1120 12,5 50 61 M  8 28 2    8 32  39  100 490 600 1520 15,25 50 68 M 10 28 2    8 52  52 115 890 890 1950 17 70 58 M 12 37 3   11 82 110 140 1150 1520 1990 14 75 89 M 12 37 3   11 66  98 125 1330 1960 2540 20 4 Type E With internal thread S With threaded stud
