SCHOTTEL OEM liner / sleeve / bushing. Sizing and material are vessel-specific — the SCHOTTEL part number identifies the part family but the bore, OD and surface treatment depend on the SRP frame size and serial number. Confirm against the vessel's parts list before order. Note: this part number identifies the SCHOTTEL part family. The exact dimensional or material specification on the as-supplied part may require confirmation against the vessel serial number and equipment data plate — confirm with the vessel's SCHOTTEL service file before final order.
