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.

Why Choose BEP Ltd?

  • Over 20 Years of Industry Trust
  • Certified OEM-Grade Components
  • Bulk Order & Trade Discounts Available

Frequently Asked Questions (FAQs)

Q1. What does 1/2" pitch mean on a roller chain?

It refers to the distance between pins — 1/2 inch (12.7mm). This is a common pitch size used in light- to medium-duty power transmission.

Q2. Can I use a 1/2" chain for high-speed applications?

Yes, many 1/2" chains are designed for high RPMs. Choose a high-tensile version and ensure proper lubrication or select a self-lube model.

Q3. What's the price of a 1/2" roller chain?

Pricing depends on the material (e.g. stainless steel, nickel-plated), length, and brand. You can view current roller chain prices on each product page.

Q4. Do you supply miniature roller chains?

Yes, we offer miniature and light-duty 1/2" chains suitable for compact machinery and low-torque drives. Contact us if you need sizing assistance.
