The 12B-2 British Standard Series Chain (19.05 mm (0.750 in / 3/4″) pitch) is manufactured to precision BS 228 / ISO 606 (12B) / DIN 8187 specifications. Engineered for European drive systems, heavy-duty industrial machinery, conveyors, and mechanical power transmission, this British Standard chain provides superior fatigue life, accurate articulation, and outstanding wear endurance under sustained operating conditions.
Key Engineering Features & Performance Benefits
- Precision Pitch Alignment: Standardized 19.05 mm (0.750 in / 3/4″) pitch and 11.68 mm (0.460 in) inner width ensure perfect tooth engagement with British Standard sprockets, minimizing vibration and wear.
- High Breaking Strength: Delivers a minimum ultimate tensile breaking load of 57.8 kN (12,994 lbf) across its double strand (duplex) design.
- Superior Wear Components: Case-hardened alloy pins and solid rollers (12.07 mm (0.475 in) diameter) deliver exceptional resistance against pin galling, chain elongation, and fatigue cracking.
- Material & Treatment: High-Grade Heat-Treated Carbon / Alloy Steel. Precision heat treatment maximizes toughness and cyclic fatigue endurance.
- Factory Pre-Stressed & Pre-Lubricated: Pre-loaded during assembly to eliminate initial stretch and treated with high-grade rust-preventative industrial lubricants.
Primary Industrial & Commercial Applications
Widely utilized across manufacturing plant drives, automated packaging lines, agricultural machinery, printing equipment, bucket elevators, and heavy material handling conveyors.
Supplied per metre. Continuous lengths can be customized or joined using matching 12B connecting links and offset crank links.
