The X-ring chain is a specialized type of sealed roller chain
Roller chain or bush roller chain is the type of chain drive most commonly used for transmission of mechanical power on many kinds of domestic, industrial and agricultural machinery, including conveyors, wire- and tube-drawing machines, pri ...
used to transfer mechanical power. Like the standard O-ring
An O-ring, also known as a packing or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more par ...

A lubricant (sometimes shortened to lube) is a substance that helps to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. It may also have the function of transmitting forces, t ...
(usually grease) in place.
It has higher performance (in terms of durability, lifetime, and power loss) than non-O-ring chains as it has less friction than O-ring chain while providing adequate lubrication and protection against foreign elements which also increases reliability. It can last twice as long as the O-ring chain under some circumstances.
Development
The X-ring chain is developed from O-ring chain which in turn is developed from non-O-ring chain. While the regular O-ring chain has high durability, it also has more friction (compared to other types of roller chains) due to distortion of the O-ring due to pressure from the inner and outer chain plates. This results in loss of power in thetransmission
Transmission may refer to:
Medicine, science and technology
* Power transmission
** Electric power transmission
** Propulsion transmission, technology allowing controlled application of power
*** Automatic transmission
*** Manual transmission
** ...
. Therefore, X-ring chain was developed by replacing O-ring seal with X-ring seal which greatly reduced friction and increased durability.
Design
Like the O-ring chain it has sealing rings which keep the contaminant (dirt) out, and lubricant in between the pins and bushings. This is known as internal lubrication. However, unlike O-ring chain, it has X shaped seal which does not experience increased surface area (which is in contact with the chain plates) when under pressure. Therefore the friction in X-ring chain does not increase much when pressure is applied by the chain plates. Due to their unique shape, they have two additional sealing surfaces to a traditional O-ring.See also
