High-Performance 1/2" Roller Chains – Built for Precision
Premium 1/2 Inch Pitch Roller Chains | BEP Engineering UK
Looking for a reliable 1/2" roller chain? At Bolton Engineering Products Ltd, we supply a complete range of 1/2 pitch chains built for durability, precision, and smooth power transmission in demanding industrial environments. Whether you need a single strand or a high-performance miniature roller chain, we’ve got your requirements covered.
What Is a 1/2" Pitch Roller Chain?
A 1/2 inch chain (commonly called 1/2 pitch chain) refers to a roller chain with a 12.7 mm pitch between each pin. It’s the most widely used size across industries like:
- Agricultural machinery
- Industrial automation systems
- Printing and packaging equipment
- Automotive camshafts and drives
- Chemical and food-grade equipment (non-lube variants)
Our roller chains are engineered to reduce friction and offer consistent, reliable operation — even under high-speed, high-load conditions.
Chain Types Available
We stock standard ANSI roller chains and specialty variants including:
- Stainless steel chains – corrosion-resistant, ideal for food or chemical use
- Zinc-plated chains – for added rust protection in outdoor environments
- Nickel-plated chains – combines strength with sleek, anti-corrosive finish
- Self-lubricating chains – designed for minimal maintenance in dry operations
Need a roller chain splitter, connector link, or chain tool? You’ll find it all in one place at BEP Ltd.
Expert Support, Hassle-Free Selection
We understand choosing the correct roller chain can be confusing — especially with various chain grades, tensile strengths, and applications to consider.
Our knowledgeable support team is available to help you:
- Select the correct pitch and tensile rating
- Identify the right replacement chain
- Match links and sprockets for full systems
Prefer to shop on your own? Our intuitive online filters help you narrow by chain size, length, plating, or application type — saving time and avoiding costly misfits.
