13 best chain breakers

Chain breakers are essential tools used in the maintenance and repair of power transmission products, specifically chains.They are widely used in various industrial and scientific applications where chains are utilized for power transmission, such as in machinery, conveyor systems, and automotive applications.

A chain breaker is a mechanical tool designed to break chains, usually to remove damaged or worn-out links and replace them with new ones. Chains need to be the right length to function properly, and chain breakers help in adjusting the chain length to fit specific applications.

The basic operation of a chain breaker involves placing the chain into the tool, positioning the chain breaker pin onto the chain link's rivet, and then turning the tool's handle to apply pressure on the pin. This pressure forces the rivet out of the chain, allowing the chain to be separated into the desired length. Chain breakers are available in various sizes and designs to accommodate different types and sizes of chains.

In the context of power transmission products, chain breakers play a crucial role in ensuring the efficiency and safety of industrial machinery and equipment. Proper maintenance of chains using chain breakers helps prevent wear and tear, reduces downtime, and extends the lifespan of the entire power transmission system.

It's important to note that chain breakers are just one part of the larger ecosystem of power transmission products, which also includes components like sprockets, gears, bearings, and couplings, all of which work together to transfer power from one mechanical system to another in industrial and scientific settings.

User questions & answers

Question: How do I know what speed my bike is? It is a 93Ose dynasty
Answer: Count the number of cogs (or rings of gear nubs) on the cassette on the rear hub. Generally, there are 7 to 11 rings on the cassette. That number is how you refer to the number of speeds of your bike for maintenance purposes. You then multiply that number by the number of chain rings (or sprockets) on the crank set; generally, it's 2 or 3. For example, if there are 3 chain rings on the crank set and 9 rings on the cassette, then your bike is a 27-speed. However, for maintenance purposes, it's a 9-speed.
Question: What diameter is the pin
Answer: I don’t know the exact diameter but it fit tightly in the space of the pin in the chain
Question: Is there replacement Push pin available to purchase for this tool
Answer: Hi, We do not sell push pins on their own, but in the event you need another we are happy to ship replacement units to previous customers.
Question: What is the pin installed in the side of the handle used for
Answer: This product has two push pins. One is pre-installed in the rotating handle. This is used to push the chain pin out of the chain - effectively breaking the chain. Due to the heavy-duty use of this product, wear and tear happens, so we include a spare pin inside of the rubber handle. It can be swapped out very simply by hand.

Question: Has anyone used this on a BMX half-link chain? have used one where the little stabilizer teeth on the tool did not have room for this thicker chain
Answer: Only used it on 21speed derailer chain... their site say, "The CT-5 is intended for derailleur chains. The wide 1/8" and 3/16" chains should use the CT-7. When pressing in or pressing out a rivet, place the chain roller over the chain tool cradle as showing in the image here."www.parktool.com... good luck

User questions & answers

Question: description say 10s but image says Less than 10s
Answer: I use it on 10 all the time. No problem.
Question: Does this work for a 12 speed chain link? Didnt think it didnt make a difference what speed chain
Answer: The width of a 12 speed bicycle chain is less than a 6 or 7 speed. It won’t fit snuggly in this chain splitter. You may be able to hold the chain in place while you push out the pin but it would be easier with the right sized tool.
Question: Suitable for #35 mini bike chains
Answer: I personally broke the tool doing it but managed to get it done. 50/50 but for the price go for it. It’s a one time use unless it’s a simple pedal bike, then twice
Question: Does this work for 11 speed sram chains
Answer: Best answer I can give is, more than likely. I think this is pretty much a universal chain splitter for derealleur type bicycle chains. I used it to fit a new chain to my grandson's 21 speed 24" Murray Mystic. It worked perfectly to remove the old rusty chain and shorten to length the new chain that I got at the local bike shop.
