Rust Prevention Hardened Chain Sprocket 40 Roller Chain Sprocket B Type 1in Bore 15 Tooth 45# Steel Gear Sprocket for Industrial Machinery Drive, 15mm/0.59in

Feature:【Hard and Strong】The roller chain sprocket is made of strong 45# steel and has enhanced wear resistance of the teeth through a heat treatment process. This design is designed to cope with the continuous friction and load in daily transmission, helping to extend the overall service life of the product and provide stable.【Anti-Rust Treatment】The chain sprocket has a special blackened surface, which not only provides a classic look, but more importantly enhances its resistance to rust and corrosion.【Various Hole Diameters】We offer you a total of 14 different inner hole diameters from 14mm/0.55in to 35mm/1.38in. You can choose the best match for the exact diameter of your machine's spindle, resulting in a tighter fit that allows you to replace or repair without being limited to a single size.【Stable Connection】The rust prevention hardened chain sprocket is designed with a standard keyway and is equipped with two set screw holes spaced at 90 degrees. This dual fixation method is designed to help the sprocket be installed more firmly on the equipment spindle, reduce loosening and slippage that may occur when starting.【Easy Maintenance】You will receive a complete 40B08A-15 tooth chain gear sprocket. Once confirmed to match your shaft diameter and chain specifications, they can usually be installed directly without additional machining.Specification:Inner Hole Dia.: 14mm/0.55in, 15mm/0.59in, 16mm/0.63in, 17mm/0.0.67in, 18mm/0.71in, 19mm/0.74in, 20mm/0.78in, 22mm/0.86in, 24mm/0.94in, 25mm/0.98in, 28mm/1.10in, 30mm/1.18in, 32mm/1.26in, 35mm/1.38inMaterial: 45# SteelColor: BlackNumber of Teeth: 15Note: Please allow for the manual measurement errors and color differences.Package Included:1 * Rust Prevention Hardened Chain Sprocket

• 【Heat treated gear tooth design】：Hardened processing on sprocket teeth improves overall bearing capacity and abrasion resistance. It suits continuous operation of mechanical transmission structure and maintains stable working performance for a long time.
• 【Integrated anti aging craft】：Special blackened surface treatment enhances daily environmental adaptability. It resists external moisture interference and keeps complete structure and smooth transmission effect in complex working scenes.
• 【Wide specification matching】：Various inner hole sizes cover most conventional mechanical spindle demands. It is convenient to select proper specification to replace old sprocket and realize quick equipment recovery.
• 【Reliable transmission stability】：Standard keyway and double set screw positioning make installation more solid. It effectively reduces position deviation in frequent start stop and variable load conditions and ensures safe operation.
• 【Labor saving equipment repair part】：Finished sprocket structure supports direct assembly without complicated modification. It is an economical and practical accessory for mechanical routine maintenance renovation and transmission system upgrading.
