Model notation identifies a family, not a fixed size. Please confirm bore diameter, outer diameter, overall length, mounting, sealing, material, and load requirements with your drawing.
Every model above links straight to the inquiry form with the model prefilled — send your quantity and destination, and we prepare the quotation.
