Inquiry (采购产品): Mast guide roller dear sirs, I have a question on the 309SZZ4 mast guide bearing It states that it is interchangeable with BCA's MG309DDA and dimmensionaly it seems to be but BCA's calls off a dynamic load rating of 11,900 and a static rating of 7,180 where yours calls of a dynamic of 19,600 and a static of 77,600. How is this possible? **** Hidden Message ***** Patrick Icardi 44256 Company: BPR/Rico Equipment E-mail: picardi@ricoequipment.com **** Hidden Message ***** picardi@ricoequipment.com
