Product Specification: The #25 roller chain 240 link total length: 5 feet/1.524m, roller diameter: 0.13"/3.3mm, pin diameter: 0.091"/2.3mm, inner plate height: 0.236"/6mm; pitch: 1/4"/6.35mm; comes with 2 free chain master links to easily replace or lengthen the existing chain.
Material: The single row roller chain is made of high-strength carbon steel and through strict process measures to provide sufficient load capacity and durability.
Strict Process Measures: The roller chain links are shot-peened during the production process, which can improve the strength and toughness of the metal. During the chain assembly process, all chain components are oriented ensuring the pins and inner plates are positioned correctly for better chain strength and longer service life.
Wide Application: The 25 roller chain is designed to reduce friction, provide higher efficiency and lower wear, and can be used to transmit power and rotational motion. Suitable for mini bikes, scooters, small power tools, handheld power tools, and more.
Note: Please confirm the chain model you need before purchasing. Regularly checking and cleaning your chain can extend its life.
