Norco Round Saddle with a 10-ton capacity has a 1-3/8" diameter for use on rams with either a 10- or 15-ton capacity. This grooved saddle protects the ram ends and provides a better gripping surface. Note: When cylinders are used with maintenance set attachments or components, the maximum system pressure must be limited to half the rated pressure. Also, local sales taxes will be applied to ALL Norco orders shipped to California.
