Heat treating is a complex process that is done to provide the optimum chain link with a more fracture resilient ductile core for shock resistance, and an extremely hard exterior surface for superior wear resistance. 4B drop forged chain is backed by an international network of companies with over 120 years of experience, and a global team of engineers that can provide you with practical solutions for all your material handling applications. | | | | | | | | | | www.go4b.com | | | | | | | | | | | | | | PIN SPECIFICATION | | | | | | | | | | | | | | | | | | | | | | | | Chain Link | 102 N-A Drop Forged | 125 N-A Drop Forged | 142 N-A Drop Forged | 142 H-A Drop Forged | 150 N-A Drop Forged | 160 N-A Drop Forged | 216 N-A Drop Forged | 260 N-A Drop Forged | | | | Minimum Breaking Load | 150 kn 33,000 lb | 175 kn 39,375 lb | 300 kn 67,500 lb | 450 kn 101,000 | 250 kn 56,250 | 260 kn 58,500 | 600 kn 135,000 lb | 700 kn 158,000 lb | | | | Case (MIN) Hardness | Rockwell C57 | Rockwell C57 | Rockwell C57 | Rockwell C57 | Rockwell C57 | Rockwell C57 | Rockwell C57 | Rockwell C57 | | | | Case Depth | 0.5 mm | 0.6 mm | 0.7 mm | 0.7 mm | 0.7 mm | 0.8 mm | 1.0 mm | 1.0mm | | | | Case Hardness | Rockwell C40 | Rockwell C40 | Rockwell C40 | Rockwell C40 | Rockwell C40 | Rockwell C40 | Rockwell C40 | Rockwell C40 | | | | Weight (per link) | 0.38 kg | 0.7 kg | 1.08 kg | 1.76 kg | 1.2 kg | 1.3 kg | 3.66 kg | 5.38 kg | | | | | Yes | Yes | Yes | Yes | Yes | Yes | No | No | | | | Dimensions | | | | P | 102 mm | 125 mm | 142 mm | 142 mm | 150 mm | 160 mm | 216 mm | 260 mm | | | | H | 36 mm | 35 mm | 50 mm | 50 mm | 49 mm | 44.5 mm | 75 mm | 75 mm | | | | W | 28 mm | 36 mm | 42 mm | 62 mm | 36 mm | 42 mm | 60 mm | 71 mm | | | | T | 7.62 mm | 10 mm | 11 mm | 16.5 mm | 13 mm | 13 mm | 19 mm | 22 mm | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |
