The 12B-G2 Rubber Top Chain is a medium-duty conveyor roller chain with vulcanized rubber pads bonded to the outer surface of each link. Manufactured to ISO 606 \/ DIN 8187 dimensional standards from heat-treated alloy steel, it combines the load-bearing reliability of a precision roller chain with the cushioned, non-slip grip that delicate workpieces demand. It is the standard choice for woodworking conveyors, glass processing lines, ceramics kilns, plywood presses, and composite board production \u2014 any environment where a bare metal chain would scratch, mark, or vibrate the product being conveyed.<\/p>\n
Two rubber compound options \u2014 NBR (nitrile, oil-resistant) and NR (natural rubber) \u2014 are available in Shore A 65\u201375 (standard handling) or Shore A 75\u201385 (higher load \/ higher speed). Both are vulcanized directly onto the chain link during manufacture, not adhesive-bonded, for permanent pad retention across the chain’s full service life.<\/p>\n

\n<\/div>\n\nSection 03<\/div>\nKey Features & Benefits<\/h2>\n<\/div>\n<\/div>\n
<\/p>\n
\n\n\n\n\n\ud83d\udd07<\/div>\nNoise & Vibration Reduction<\/p>\n
Vulcanized rubber pads absorb impact and dampen vibration at every product contact point. Measurably quieter than bare rantai logam<\/a> \u2014 critical for enclosed woodworking halls and glass processing facilities where OSHA noise thresholds apply.<\/p>\n<\/div>\n<\/td>\n
\n\n\ud83d\udee1\ufe0f<\/div>\nSurface & Workpiece Protection<\/p>\n
Rubber pads prevent metal-on-product contact, eliminating scratches and pressure marks on finished wood panels, glass sheets, and ceramic tiles. Essential wherever surface quality is a downstream quality KPI.<\/p>\n<\/div>\n<\/td>\n<\/tr>\n
\n\n\n\ud83d\udcaa<\/div>\nHigh Tensile Strength \u2014 57.8 kN<\/p>\n
Solid roller construction and heat-treated alloy steel components deliver a minimum breaking load of 57.8 kN (13,136 lbf). Engineered for continuous conveying under sustained load, not just peak-rated performance.<\/p>\n<\/div>\n<\/td>\n
\n\n\u2699\ufe0f<\/div>\nPrecision Manufacturing<\/p>\n
Manufactured to ISO 606 tolerances with shot-peened pins and plates for improved fatigue life. Roller and pin clearances are held to tight dimensional limits to ensure smooth, low-vibration sprocket engagement through the chain’s full service life.<\/p>\n<\/div>\n<\/td>\n<\/tr>\n
\n\n\n\ud83e\uddea<\/div>\nDual Rubber Compound Options<\/p>\n
NBR<\/strong> compound resists oil, fuel, and hydraulic fluid contact \u2014 ideal for lubricated conveyor environments. NR<\/strong> compound provides higher elasticity and better low-temperature performance. Both are available in two hardness grades to match your load and speed profile.<\/p>\n<\/div>\n<\/td>\n\n\n\ud83d\udd29<\/div>\nDirect Sprocket Compatibility<\/p>\n
Designed to pair with standard 12B sprockets or matching 12B rubber-tooth sprockets<\/strong> (rubber-inlaid teeth reduce engagement noise by a further 3\u20135 dB). Sprockets available in pilot bore and finished bore configurations.<\/p>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/p>\n

\n<\/div>\n\nSection 04<\/div>\nInstallation Guide<\/h2>\n<\/div>\n<\/div>\n
<\/p>\n
\n\n1<\/div>\n\nClean Sprockets & Chain<\/p>\n
Use a mild solvent to clean all sprocket faces and chain link surfaces. Dry completely before installation \u2014 oil or grease contamination compromises rubber pad adhesion and accelerates delamination over time.<\/p>\n<\/div>\n<\/div>\n
\n2<\/div>\n\nVerify Sprocket Alignment<\/p>\n
Use a straightedge or laser alignment tool to confirm both sprockets are co-planar. Angular and parallel misalignment are the leading causes of premature rubber pad cracking and accelerated side-plate wear.<\/p>\n<\/div>\n<\/div>\n
\n3<\/div>\n\nRoute & Install the Chain<\/p>\n
Start routing from the smallest sprocket, working toward the drive sprocket. Keep the chain taut as you work \u2014 do not force links over teeth. If you feel resistance, recheck that the pitch matches the sprocket specification (12B = 19.050 mm).<\/p>\n<\/div>\n<\/div>\n
\n4<\/div>\n\nSet Correct Tension<\/p>\n
Target 2\u20133% sag over a free span using a chain tensioner. Over-tensioning accelerates pin and bushing wear; under-tensioning causes skipping under load and increases shock loading on the rubber pads.<\/p>\n<\/div>\n<\/div>\n
\n5<\/div>\n\nLubricate \u2014 Correctly<\/p>\n
Apply a light chain oil to the pin-bushing interface only<\/strong>. Do not<\/em> lubricate the rubber pad surfaces \u2014 oils and greases degrade rubber compounds and reduce grip on the conveyed product.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/p>\n
\n\u26a0\ufe0f<\/div>\n\nMaintenance Interval Recommendation<\/p>\n
Inspect rubber pads every 500 operating hours<\/strong> for cracking, chunking, or delamination. Replace the chain section when rubber hardness falls below Shore A 55 (oil\/heat aging) or pad height loss exceeds 2 mm. Retain worn sections for supplier warranty assessment.<\/p>\n<\/div>\n<\/div>\n<\/p>\n
\n<\/div>\n\nSection 05<\/div>\nMatching Sprockets<\/h2>\n<\/div>\n<\/div>\n
We supply matching 12B rubber-top sprockets<\/strong> engineered to mesh precisely with the 12B-G2 chain. The sprocket tooth profile follows ISO 606 Series B geometry; rubber inserts between teeth absorb engagement shock and reduce meshing noise by a further 3\u20135 dB versus standard metal sprockets.<\/p>\n\n\n\nParameter<\/th>\n 12B Rubber-Top Sprocket<\/th>\n<\/tr>\n<\/thead>\n \n\nChain Pitch Match<\/td>\n 19.050 mm (ISO 606 Series B)<\/td>\n<\/tr>\n \nRoller Grade<\/td>\n G2 \u2014 medium load capacity<\/td>\n<\/tr>\n \nTooth Material<\/td>\n Carbon steel body with vulcanized rubber tooth inserts<\/td>\n<\/tr>\n \nNoise Benefit<\/td>\n 3\u20135 dB reduction at engagement vs. bare metal sprockets<\/td>\n<\/tr>\n \nBore Options<\/td>\n Pilot bore \/ finished bore with keyway & set screw<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/p>\n
