Abstract: A high deflection, radial seal for sealing a rotating shaft includes an annular mounting member including a primary seal lip having an annular sealing surface for sealing against an outer surface of the rotating shaft; an annular spring engages and energizes the annular mounting member and an inner annular ring is over-molded in the annular mounting member and aligned concentric with the annular sealing lip and the inner annular ring engages and seals the rotating shaft and the inner annular ring includes a plurality of cross holes along an inner circumference and located axially between the annular sealing lip and the annular ring. The annular member further includes a convoluted member extending radially and axially and including a static side member extending axially from the convoluted member; and an outer annular ring over molded on an outer side of the static side member of the annular mounting member.

Abstract: A tensioning device for installing tree stands that includes a drive end and a cable output end to attach to a medium that is placed around a tree. The tensioning device creates more tension in the medium than is generally able to be applied by hand with ratchet straps or chains, which provides safer installation of a tree stand or climbing ladder. The tensioning device includes a drive system that can be driven with standard power tools or hand tools to retract a cable. The tensioning device may be designed with or without a clutch feature. The clutch feature allows for a desired cable tension to be reached for each installation and provides feedback to the operator when the correct tension is reached. The tensioning device includes an external bracket or hook for easily attaching to a tree stand or climbing ladder.

Abstract: A tensioning device for tie down applications in a utility market that includes a drive end and a cable output end to attach to a medium, item, or truck or trailer. The tensioning device creates more tension in the medium than is generally able to be applied by hand with ratchet straps or chains, which provides a more secure tie down of items in a utility application. The tensioning device includes a drive system that can be driven with standard power tools or hand tools to retract a cable. The tensioning device may be designed with or without a clutch feature. The clutch feature allows for a desired cable tension to be reached for each installation and provides feedback to the operator when the correct tension is reached. The tensioning device includes an external bracket or hook for easily attaching to an item, medium, or truck or trailer.

Abstract: A method and apparatus for expanding a free end of a tube by use of a fluted spinning tool. The fluted spinning tool of the present invention, when rotated at a predetermined speed into the free end of the tube, produces a combination of force, rotation, and heat which results in uniform expansion of the free end of the tube. Further, the fluted spinning tool of the present invention allows for the rapid and efficient production of expanded tube parts, such parts being evenly formed with minimal bias on the expanded free ends of the tubes.
