#25 Chain Roller Sprocket 12mm Bore 53.5mm OD, 25 Tooth C45 Carbon Steel ANSI #25 Roller Sprocket Round Hole Without Surface Finished with 4x1.8mm Keyway for ISO 04C Chain

Key Features

• Model #25 Roller Chain Sprocket B Type 25 Tooth, 12mm Bore, 6.35mm (1/4") Pitch, 4x1.8mm(0.16"x0.07") Keyway, for ISO 04C Chain.
• Material The sprocket is made of C45 carbon steel, which is rust-proof. The tooth part uses high-temperature quenching heat treatment, high hardness, wear resistance, a long service life, and is easy to use
• Design Each roller sprocket is equipped with strong teeth to lock the chain well. There are round holes for installing set screws that form a 90-degree angle with the set screw after installation, which can fix the shaft and prevent it from slipping. （Set screws are not included in the package）
• Installation Chain Sprockets are normally mounted in a fixed position on a fixed shaft. The chain sprocket should not rotate at a greater speed than is allowable for drive sprockets of the same size. It is suggested that chain sprockets have at least three teeth in mesh with the chain
• Wide Application Sprockets can be used in various industrial areas, especially in power transmission industrial machinery, such as milling machines, drilling machines, drilling rigs, or other mechanical transmission occasions
