With an 8mm bore and round holes for secure set screw installation, it guarantees stable shaft fixation and optimal chain engagement. Engineered for ISO 04C #25 roller chains, this sprocket excels in industrial power transmission applications like milling and drilling, delivering durability and reliable performance. ## Description Description: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.Specification:Material: C45 Carbon SteelOutside Diameter: 51.5mm / 2.03-inchBump Thickness: 12mm / 0.47-inchBump Diameter: 35mm / 1.38-inchTotal Thickness: 15mm / 0.59-inchBore Diameter: 8mm / 0.31-inchTooth Thickness: 3mm/ 0.12-inchPitch: 1/4-inch / 6.35mmNumber of Teeth: 24Package Content:1 x Chain Sprocket ## Features - Model: #25 Roller Chain Sprocket B Type 24 Tooth, 8mm Bore, 6.35mm (1/4") Pitch for ISO 04C Chain. - Material: The sprocket is made of C45 carbon steel, which is rust-proof.
