BS – British Standard Transmission Chains (BS)

Name: Precision Chains Limited
Address: Clee Rd, Dudley, West Midlands, DY2 0YG
Telephone: +44 1384 455 455

British Standard transmission chains are manufactured according to BS ISO 606 standards and are widely used in water treatment applications across Europe and other regions. These chains are known for their robust design and precision, making them ideal for handling heavy loads in environments prone to wear and tear. Key features include:

Pitch Sizes: BS chains are available in smaller pitch sizes compared to ANSI chains, making them more compact and suited for specific machinery in water treatment plants.
Corrosion Resistance: They are typically made from high-grade materials with surface treatments to ensure high resistance to corrosion and chemical exposure, which is crucial in water treatment facilities.
Applications: BS transmission chains are frequently used in European-style water treatment machinery, including sludge conveyors, aeration systems, and chemical dosing mechanisms.

Chains manufactured by Group company John King Chains Limited in England.
