美国采购需求：山猫、凯斯、卡特彼勒、斗山、挖掘机

I'm interested in getting details about a replacement hydraulic cylinder for a specific thumb model. The cylinder I need is part of your catalog, particularly the 50mm variant. It's important to note that the hydraulic cylinder eyes are designed to accommodate 40mm pins. Could you please provide me with pricing and availability for this product? If you require additional information or specifications to assist with my request, don't hesitate to ask. Looking forward to your prompt response.
