Each other fully, with the long life span, excellent stability and high precision. 4.Converse installation: A.The structure is the same as the single way installation, which can control the lower gear precisely and long time Using can't cause it reverses; with extremely high stability and precision. B.Inaccurate feeding distance and the brake failure caused by the grease splashed during impact are impossible. C.High heat is hard to produce. D.Adopt the super hard alloy and roller; uneasy to be wore out. E.Roller runs in circle and the stuck can not be caused easily. F.Low friction, the rotation torque is reduced and the rotating mechanism can not be damaged easily. G.The converse installation speed reaches 30 meters/minute, and normally it is 20 meters/minute, which increase 50%. H.Special structure prolonged the lifespan Model Roller width Feeding length(mm) Material thickness (mm) Material line Height (mm) Press capacity Size Weight A B C D E F G M Lh-105ns 100 50 0-1.6 55-100 5-20 537 247 250 292 200 95 295 120 64 Lh-205ns 200 50 0-1.6 55-100 20 637 347 270 342 220 125 345 120 87 Lh-255ns 250 50 0-1.6 55-100 20 687 397 270 367 220 125 345 120 95 Lh-305ns 300 50 0-1.6 55-100 40 737 447 270 392 220 125 345 120 103 Lh-355ns 350 50 0-1.6 55-100 40 787 497 270 417 220 125 345 120 111 Lh-405ns 400 50 0-1.6 55-100 60 837 547 270 442 220 125 345 120 121 Lh-455ns 450 50 0-1.6 55-100 80 887 597 270 467 220 125 345 120 101 Lh-505ns 500 50 0-1.6 55-100 80 937 647 310 492 220 125 345 120 141 Lh-555ns 550 50 0-1.6 55-100 110 987 697 410 517 220 125 345 120
