I'm looking for a supplier for some components related to roller chains and locking links. Specifically, I need a single roller chain with specific dimensions and links that match certain standards. The chain should be durable and suited for heavy-duty applications, as it's essential for our ongoing projects. Additionally, I require locking links that align with the previously mentioned chain specifications. It's crucial for the links to provide secure connections and maintain optimal performance in mechanical systems. Please provide availability, pricing, and lead times for both items, as well as any additional relevant details that may assist in the decision-making process. Looking forward to your prompt response!
