Trunnion

Trunnion attachments can be mounted at the cap-end, rod-end, or at an intermediate position. Trunnion attachments include pins for rotation and are secured on both sides of a cylinder. Trunnion brackets are rigidly secured to a mounting surface and used as a rotation point for trunnion pins. Rotation about a trunnion attachment is similar to clevis attachments; however, they can only be used with shear stresses and not bending stresses. To reduce bending stresses, it is recommended that the trunnion bracket is tightly fit to the trunnion pins.
