Abstract
A silo includes a stuffing box forming for use with a reciprocating frame. A push-rod extends from a hydraulic cylinder through a stuffing box and a silo wall to actuate a reciprocating frame. The stuffing box forms a floating seal around the push-rod capable of moving with the push-rod to accommodate misalignment.
