How Is Bicycle Chain Made?

What material is a bike chain made of?

A bicycle chain is a roller chain that transfers power from the pedals to the drive-wheel of a bicycle, thus propelling it. Most bicycle chains are made from plain carbon or alloy steel, but some are nickel-plated to prevent rust, or simply for aesthetics.

Is bicycle chain made from stainless steel?

Because they’d cost too damned much, they’re meant to run lubricated, and carbon steel can be made harder/stronger anyhow. Bike chains require oil for lubricating purposes. That also protects them from rust. So there is no advantage in stainless steel.

How are roller chains manufactured?

The manufacturing operation of roller chains involves drawing and trimming processes aimed at producing semi-finished chain drives component with a well-standardized dimension. Ears and un-uniform wall thickness have been identified as a key problem in the mass production of component.

Are all bike chains equal?

All modern bicycle chains are made to the “one-half inch pitch” standard, meaning from rivet to rivet is nominally 0.5 inches. The sprocket teeth are cut for this same one-half inch standard to accept bicycle chains. However, this does not mean all makes and models of chains are interchangeable.

What is a bicycle chain link?

The master link is a single removable link segment of a bicycle chain. You’ll hear people also refer to these as quick links. Also, SRAM’s version of the master link is called a Power Link. It is sold separately as well as typically included when you buy a SRAM chain.

What does a chain symbolize?

Today the concept of a chain (or interlocking structures) is fairly common in logo design and seen as symbolic of unity, teamwork and strength.

How is chain welded?

Chain is produced in small groups of equipment, or cells. The chain then passes to the welder where each link is machine welded electrically with no filler by heating the edges of the wire ends and forging them together. The excess material is trimmed.

Why is my bike chain rusting?

When the chain is exposed to moisture, it causes new chemical reactions to occur via a process known as oxidation. This literally transforms part of the metal into a new type of metal: iron oxide (aka rust). Note: Other things can speed up the formation of rust, such as exposure to road salt and mud.

When should I replace my bike chain?

Anything at or beyond the 0.75 percent reading means that you should change your chain immediately. If you are using a chain designed for ten or fewer gears, replace your chain as it nears the 0.75 percent mark. If you are using an eleven or twelve speed chain, replace your chain once it has reached 0.5 percent wear.

How many links should be in my bike chain?

Bicycle drive chain length A new bicycle chain usually comes with 116 links. This is long enough for the biggest chainrings and for most distances of rear wheel from front chainrings. So for optimal length a new chain is usually shortened from the 116 links that come in the box.

What are the types of chain drive?

Types of Chains Used in Power Transmission

  • Roller chain.
  • Silent chain.
  • Leaf Chain.
  • Flat-top Chain.
  • Engineering Steel Chain.

Why would you use a belt drive instead of a chain?

Unlike chain drive, which requires very frequent cleaning, tightening and maintenance, belt drives are relative maintenance free. Belt drive systems also run much smoother, with much less jerks as compared to chain drives, and produce incomparably less noise too.

What is chain pitch?

Chain size is commonly referred to as Pitch. In actuality, chain size is determined by the chain pitch. Pitch refers to the measurement from one roller-pin center to the next roller pin center of a given chain. ANSI (American National Standard Institute) chain pitch is always measured in 1/8” increments.
