NAAMS Clevis Components

Click Here to See Category Description

NAAMS clevis assemblies and components are standardized to streamline automated manufacturing, helping to reduce costs and speed up design times. These assemblies connect cylinders to pivot units for smooth operation and are made from cast steel with options for 2-hole or 4-hole tap configurations. Available heights include 95 mm, 125.5 mm, 155 mm, and 240 mm. The composite bearings feature a reinforced Teflon liner and a fiber-reinforced epoxy shell. For complete specifications on clevises, pins, bearings, keepers, and screws, refer to the relevant NAAMS codes.

We offer all assemblies and individual components both current and discontinued. Browse here for the part you are looking for or click on the respective NAAMS code.
