tooloflife 4PCS Roller Chain Connecting Link Offset Half Link for Motorcycle Bicycle Conveyor Machinery (12B-1)

Feature:【Easy Installation】This roller chain offset half link is a special connection for the chain, with a classic half-buckle design. Whether you're installing a new drive chain or quickly repairing an existing one, you can easily engage it by aligning the half buckle with both ends of the chain and fitting the connecting pin (not included). Its intuitive structural design eliminates the need for complex tools or specialized skills, greatly simplifying the chain assembly and repair process.【Hard and Rust-Proof】This crank link is made of high-quality carbon steel as raw material through precision forging and processing. This material has good strength and wear resistance, supplemented by anti-rust treatment, making it effectively resistant to wear, stretching and oxidation in daily use, ensuring long-lasting and stable connection in the transmission system and extending the service life of the entire chain assembly.【Various Models】We offer 9 models for you to choose from: 12A-1, 12A-2, 12B-1, 16A-1, 16A-2, 16B-1, 20A-1, 20A-2 and 24A-1 to meet the replacement needs of different types of equipment. They are widely used in motorcycles, bicycles, agricultural machinery, conveyor equipment, packaging machinery and various light industrial transmissions.【Stable Connection】This carbon steel half roll chain connecting link is finely processed to fit tightly with the corresponding specification chain. The connecting pin and the chain plate hole are properly matched, and after locking, they can effectively share the tension of the chain during operation, helping to keep the chain aligned in a straight line and reduce abnormal wear, thereby ensuring the smoothness and reliability of the transmission process.【Sufficient Quantity】Each specification of the roller chain offset half link comes in a pack of 4. This package quantity meets the needs of a single repair or assembly, and also leaves a margin for you to pick up as you go. Reasonable inventory allows you to manage common repair parts for a variety of situations and facilitate the maintenance of your equipment.Specification:Model: 12B-1Material: Carbon SteelColor: Silver with Dark GrayNote: Please allow for the manual measurement errors and color differences.Package Included:4 PCS * Crank Links
