The designation 31x43x10 provides critical dimensions of the oil seal. Here, 31 indicates the inner diameter (ID) in millimeters, 43 represents the outer diameter (OD), and 10 denotes the width of the seal in millimeters. The oil seal also has a percentage component, possibly alluding to its material composition or operational pressure resistance, although further context is required for precise interpretation.

The 35x72x10 oil seal typically has a robust design, often comprising a rubberized material or thermoplastic elastomer, capable of withstanding a wide range of temperatures and pressures. This make-up ensures that the seal maintains its integrity even in harsh working environments.
