What is the 08B-G2?<\/h2>\n
\n

08B<\/strong> = ISO series, 12.7\u2009mm (\u00bd\u2033) pitch \u2014 the most widely stocked size globally, meaning matching sprockets are readily available.\u2002G<\/strong> = rubber top attachment.\u20022<\/strong> = double-strand construction: two parallel rows of link plates and rollers on shared pins, delivering roughly twice the tensile strength of the 08B-G1 single-strand variant.<\/p>\n<\/div>\n

\"RantaiThe rubber top pad is vulcanised directly onto the outer plate of each link, projecting above the pitch line to contact the load or conveyed object. NBR is the default for oil and grease resistance; NR offers superior resilience on dry surfaces. Both compounds come in two hardness grades, allowing engineers to tune friction coefficient and compression set to their specific application.<\/p>\n

We manufacture this chain from alloy steel as standard, with stainless steel (SS304 \/ SS316) available for washdown, food-grade, or corrosive environments. All steel stock carries mill certificates traceable to heat number.<\/p>\n

<\/p>\n

Key advantages<\/h2>\n
\n
\n
\u25b6 Enhanced grip<\/div>\n

Vulcanised rubber surface increases friction against conveyed goods, eliminating slip on inclined or variable-speed runs.<\/p>\n<\/div>\n

\n
\u25b6 Noise reduction<\/div>\n

Rubber absorbs impact at every link engagement \u2014 typically 3\u20138\u2009dB quieter than bare steel chains. Essential for food, pharma, and packaging lines.<\/p>\n<\/div>\n

\n
\u25b6 Lower wear rate<\/div>\n

Pad cushions contact forces, reducing surface scoring on both chain and product, extending maintenance intervals and lowering total cost of ownership.<\/p>\n<\/div>\n

\n
\u25b6 Double-strand strength<\/div>\n

Two parallel strands on shared pins deliver 32.0\u2009kN minimum tensile \u2014 suitable for shock-loaded systems and heavy conveying applications.<\/p>\n<\/div>\n

\n
\u25b6 Contamination resistance<\/div>\n

Rubber top shields outer plates from dust, wood chips, and moisture ingress \u2014 proven in woodworking, plywood production, and outdoor installations.<\/p>\n<\/div>\n

\n
\u25b6 Material flexibility<\/div>\n

Alloy or stainless steel, NBR or NR rubber, two hardness grades \u2014 fully configurable to your duty and environment. OEM specifications accepted.<\/p>\n<\/div>\n<\/div>\n

\n
\ud83d\udc89<\/span><\/div>\n
\n
Medical device assembly<\/div>\n
Low vibration and particle-free rubber formulations keep assembly environments clean. Ideal for semi-clean-room adjacent conveying.<\/div>\n<\/div>\n<\/div>\n
\n
\ud83c\udf3e<\/span><\/div>\n
\n
Agricultural and outdoor equipment<\/div>\n
Weather-resistant rubber protects the chain in high-dust, high-humidity harvest environments; stainless option prevents outer plate rust.<\/div>\n<\/div>\n<\/div>\n
\n
\u2699<\/span><\/div>\n
\n
General light manufacturing conveyors<\/div>\n
Replaces belt-over-chain solutions where belt tracking is unreliable or contamination from rubber crumb is not acceptable.<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Rantai rol karet 08B-G2 adalah jenis rantai rol yang umum digunakan pada mesin industri. Rantai rol digunakan untuk mentransmisikan daya antara poros yang berputar, dan ukuran 08B adalah sebutan umum untuk rantai dengan jarak antar pusat rol (pitch) 1 inci. Huruf \u201cG2\u201d pada namanya menunjukkan bahwa rantai karet ini memiliki konstruksi untai ganda, artinya memiliki dua set rol dan pelat penghubung paralel yang berdampingan. Fitur utama rantai karet 08B-G2 adalah lapisan karet yang diaplikasikan pada bagian atas rol rantai. Lapisan ini memberikan daya cengkeram yang lebih baik dan ketahanan aus yang lebih tinggi, sehingga rantai rol karet 08B-G2 ideal untuk aplikasi di mana selip atau peregangan dapat menjadi masalah.<\/p>","protected":false},"featured_media":716,"comment_status":"open","ping_status":"closed","template":"","meta":{"_et_pb_use_builder":"","_et_pb_old_content":"","_et_gb_content_width":""},"product_brand":[],"product_cat":[1401],"product_tag":[],"class_list":["post-675","product","type-product","status-publish","has-post-thumbnail","product_cat-roller-chain","first","instock","shipping-taxable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/roller-chain-manufacturers.com\/id\/wp-json\/wp\/v2\/product\/675","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/roller-chain-manufacturers.com\/id\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/roller-chain-manufacturers.com\/id\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/roller-chain-manufacturers.com\/id\/wp-json\/wp\/v2\/comments?post=675"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/roller-chain-manufacturers.com\/id\/wp-json\/wp\/v2\/media\/716"}],"wp:attachment":[{"href":"https:\/\/roller-chain-manufacturers.com\/id\/wp-json\/wp\/v2\/media?parent=675"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/roller-chain-manufacturers.com\/id\/wp-json\/wp\/v2\/product_brand?post=675"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/roller-chain-manufacturers.com\/id\/wp-json\/wp\/v2\/product_cat?post=675"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/roller-chain-manufacturers.com\/id\/wp-json\/wp\/v2\/product_tag?post=675"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
