\"D\u00e2y<\/strong>The 12B-G1 Rubber Top Chain \u2014 also called a G1-type rubber bridge chain<\/em> ho\u1eb7c non-marking conveyor chain<\/em> \u2014 combines the structural integrity of a standard 12B-1 roller chain with a factory-bonded rubber pad that sits above the link plates. The pad is the only element that contacts the conveyed product, keeping steel away from finished surfaces throughout the entire conveyor run.<\/p>\n

At roller-chain-manufacturers.com we produce 12B-G1 chain to ISO\/DIN\/BS drawing tolerances in alloy steel and stainless steel, with NBR or natural-rubber (NR) top pads and your choice of rubber hardness. Every production batch is shipped with material certificates and dimensional inspection reports.<\/p>\n

5 Performance Advantages<\/h2>\n<\/div>\n

<\/p>\n

\n
\n

01<\/p>\n

Non-Marking<\/p>\n<\/div>\n

\n

Surface Protection \u2014 Zero Metal-to-Product Contact<\/p>\n

The rubber pad is the only element that touches the conveyed product. For finished wood panels, float glass, and lacquered boards, a single chain-mark causes rejection. The G1 pad eliminates that risk across the entire conveyor run, reducing scrap and rework costs in downstream QC.<\/p>\n<\/div>\n<\/div>\n

<\/p>\n

\n
\n

02<\/p>\n

Long Life<\/p>\n<\/div>\n

\n

Pad Damping Extends Chain Service Life 20\u201330%<\/p>\n

The rubber bridge absorbs impact energy at every product contact point, reducing peak dynamic loads transmitted to the roller and pin. Lower Hertzian stress at the bushing\u2013roller interface means the chain stretches more slowly. In woodworking lines, observed replacement intervals are typically 20\u201330% longer than bare-metal chain under equivalent duty.<\/p>\n<\/div>\n<\/div>\n

<\/p>\n

\n
\n

03<\/p>\n

Full Strength<\/p>\n<\/div>\n

\n

29.0 kN Minimum \u2014 No Derating Required<\/p>\n

Adding the rubber top does not reduce structural chain strength. The minimum tensile strength of 29.0 kN (6,591 lbf) is identical to a standard 12B-1 chain. The G1 variant mounts on the same sprockets and fits into the same drive calculations \u2014 no re-engineering of the existing conveyor frame or drive components.<\/p>\n<\/div>\n<\/div>\n

<\/p>\n

\n
\n

04<\/p>\n

Quiet Run<\/p>\n<\/div>\n

\n

Vibration Isolation \u2014 Measurable Noise Reduction<\/p>\n

The rubber pad acts as a vibration isolator between the chain strand and the conveyed load. In panel-processing lines running at sustained speeds, this reduces airborne noise and structure-borne vibration reaching the machine frame \u2014 improving the working environment without additional acoustic enclosures or damping mounts.<\/p>\n<\/div>\n<\/div>\n

<\/p>\n

\n
\n

05<\/p>\n

Low Maint.<\/p>\n<\/div>\n

\n

Rubber Pad Shields Outer Plates from Abrasive Contact<\/p>\n

On ceramic tile and glass lines, direct abrasive contact is the primary cause of accelerated plate wear. The rubber top shields the outer plate surface, significantly reducing abrasive wear between lubrication cycles. Standard lubrication interval remains 250\u2013500 operating hours, same as conventional roller chain.<\/p>\n<\/div>\n<\/div>\n

Sprocket Compatibility & Selection<\/h2>\n<\/div>\n
\n

The 12B-G1 d\u00e2y x\u00edch cao su ph\u00eda tr\u00ean<\/a> runs on standard 12B sprockets \u2014 the rubber pad sits above the sprocket tooth envelope and does not affect engagement geometry. Sprocket specification follows BS\/ISO 12B: tooth form to ISO 606, bore and keyway to customer drawing or standard range. We supply matched sprockets in C45 steel (induction-hardened tooth flanks, suitable to 60 HRC) or cast iron for low-speed, low-load installations.<\/p>\n<\/div>\n

\n

\u26a0 Replacement note:<\/strong> Always inspect sprocket wear before fitting new 12B-G1 chain. A worn sprocket accelerates pitch elongation of new chain by up to 3\u00d7, negating the extended service life the rubber pad provides. Replace sprockets with a measured pitch wear of >2% from nominal.<\/p>\n<\/div>\n

\n

Lubricant Type<\/p>\n

Synthetic chain oil ISO VG 100\u2013220<\/p>\n

Avoid aromatic petroleum oils with NBR pads \u2014 causes pad swelling.<\/p>\n<\/div>\n

\n

Application Method<\/p>\n

Lower-strand inner-plate gap<\/p>\n

Wipe excess off rubber surface \u2014 prevents product contamination.<\/p>\n<\/div>\n

\n

Pad Inspection<\/p>\n

Replace chain if pads show cracking, chunking, or \u226550% compression loss.<\/p>\n<\/div>\n

\n

Cleaning<\/p>\n

Warm water or mild detergent<\/p>\n

Never solvent-wash rubber-top chains \u2014 degrades pad bonding adhesive.<\/p>\n<\/div>\n
