摘要： A linear actuator is provided having a housing with a bore having at least first and second portions extending therethrough. The second portion has a polygonal geometry with substantially rounded corners having at least one planar bearing surface. A shaft is in sliding engagement with the first portion of the bore, and a piston member is operatively coupled to the shaft. The piston member has a mating geometry to the second portion of the bore, wherein the piston member is in sliding engagement with the second portion of the bore. An anti-rotation member is coupled to the piston member or shaft and has a generally D-shaped geometry with a planar anti-rotation bearing surface. Contact between the anti-rotation member and the housing is limited to a sliding engagement between the anti-rotation bearing surface and one of the at least one bearing surfaces based on an orientation of the anti-rotation member.

摘要： A fluid actuated piston and cylinder assembly with a cylinder housing having a head end and a cap end with a piston slidably reclined within the cylinder. A piston rod is attached to the piston for sliding movement with respect to the cylinder housing between an extended position and a retracted position with the piston rod extending out of the head end of the cylinder housing. A linear bearing assembly is interposed between the cylinder housing and piston rod for slidably engaging the piston rod along the axial direction with respect to the cylinder head. The linear bearing assembly frictionally engages the rod to prevent relative rotation motion between the piston rod and the cylinder.

摘要： A rotation-preventing slide is provided for a linear actuator which includes a housing which defines an internal bore and a piston-rod assembly which linearly moves within the internal bore in response to fluid pressure. The rotation-preventing slide is connected to and moves with the piston-rod assembly within a guide defined by the housing and has a geometry (e.g., polygonal, rectangular, square) which prevents rotation of the piston-rod assembly. The slide may include a bearing block and an attachment member which extends through an opening in the bearing block and which is removably attached to the piston-rod assembly whereby the slide's bearing surface (e.g., the bearing block) may be easily replaced. The guide may be a guide slot position parallel to, but axially offset from, the internal bore.

摘要： A pressure fluid cylinder with anti-rotation feature, includes a cylinder tube of non-circular inner cross section and a piston which is sealingly received in the tube. The piston has a circular cross section and is connected at one end to a piston rod in coaxial relationship. In order to allow selective use of the pressure fluid cylinder with or without anti-rotation feature, an annular adapter is placed between the piston and the tube and has a circular inner surface area to complement a circular outer surface area of the piston so as to allow a relative rotation between the piston and the adapter. The adapter has a non-circular outer surface area to complement the non-circular inner surface area of the tube. Through insertion of a fastener in aligned boreholes of the adapter and the piston, the adapter and the piston are prevented from rotating relative to one another.
