About This Product

■Product description

This is the most widely used transmission roller chain, with high dimensional accuracy, excellent wear resistance, and fatigue resistance. The standard is JIS standard No. 25-240. Heavy load roller chains are also available for transmitting large amounts of power such as in construction machinery. An O-ring chain is a chain that uses an "O-ring" to prevent oil from running out. Suitable for use in situations where lubrication is impossible or difficult, environments where lubrication (lubricating oil) is disliked, or environments with a lot of dust.

■Caution

O-ring chains contain lubricating oil between the pin and bush. Be careful not to leak lubricant when cutting or joining the chain. If it leaks, it will rapidly wear out.
