35 Roller Chain(140)

The #35 roller chain is a popular size used for mini bikes, go karts, and small machinery. It features a pitch of 3/8 inch (the distance between roller centers), a roller diameter of about 0.200 inch, and a width between inner plates of roughly 0.188 inch. This size is commonly chosen for its balance of strength and compact design. If you’re replacing a chain, double-check your equipment’s specs to ensure compatibility with #35 roller chains.

No, a 420 chain is not the same as a #35 roller chain. While both are used in powersports and machinery, they differ in pitch, width, and roller diameter. The 420 chain has a pitch of 1/2 inch, making it larger than the #35 chain’s 3/8 inch pitch. Always check your equipment’s requirements before choosing a chain, as using the wrong size can affect performance and safety.

The strength of a #35 roller chain depends on the materials and construction. Heavy-duty chains are typically made from hardened steel and feature riveted links for added durability. Some chains are designed for high-performance applications, like racing go karts or mini bikes, and may offer reinforced plates or thicker rollers. For demanding uses, look for chains labeled as "heavy duty" or "industrial grade" and always check the manufacturer’s specifications for tensile strength ratings.

• First, measure the required length for your equipment.
• Use a chain breaker tool to adjust the chain length if needed.
• Fit the chain onto the sprockets, making sure it sits properly on the teeth.
• Connect the ends using a master link, ensuring it’s securely fastened.
• Check for proper tension and alignment before use.

Following these steps can help your chain run smoothly and safely. Always refer to your equipment’s manual for specific installation instructions.

Yes, #35 roller chains are widely used on mini bikes, especially models with engines ranging from 79cc to 105cc. They’re chosen for their compact size and reliable performance. Before installing, confirm your mini bike’s sprocket size and compatibility with #35 chains. Using the correct chain size helps maintain smooth operation and reduces wear on your bike’s drivetrain components.
