Abstract: The pulldown apparatus may comprise a main stage and a secondary stage. The main stage may comprise a cylinder, a main head, a main gland, a piston and a main rod. The cylinder defines a chamber and includes a first end and a second end. The main gland and the piston is disposed in the chamber. The main rod is disposed in the chamber between the piston and the second end. The secondary stage includes a secondary head, a secondary gland, a secondary rod and a flange. The secondary gland is disposed in the chamber. The secondary rod is coupled to the flange. The flange is coupled to the main stage and disposed inside the cylinder between the piston and the secondary rod. The cylinder is slidable over the main rod, the piston and the secondary rod.

Abstract: Wear bands for heavy duty struts are disclosed. The wear bands include multiple layers such as a base metal layer sandwiched between an outer layer and an intermediate layer along with a solid lubricant layer disposed opposite the intermediate layer from the base metal layer. The outer layer engages an interior surface of the strut housing, which slidably accommodates a rod. The solid lubricant layer, which is the innermost layer, engages an outer surface of the rod so that the wear band is sandwiched between the rod and the housing and provides a solid lubricant layer for engaging the sliding rod.

Abstract: An example hydraulic system component of a machine includes a protective coating deposited by high velocity air fuel (HVAF) thermal spray, exhibiting high adhesion strengths and surface morphologies that promote lubricant adhesion and reduce the leakage of oil and/or hydraulic fluid from the hydraulic system. The coating may have surface roughness with RZ values less than 2 μm and hardness of 1000 Vickers or greater. The HVAF coating may be thinner than conventional coatings with thicknesses less than 100 μm. The HVAF coating may be deposited on a variety of steel components with adhesion strengths greater than those achieved by high velocity oxygen fuel (HVOF). The HVAF coating may be formed without time consuming roughening and/or post-grind operations, resulting in cost savings compared to conventional coatings. The coatings may have operational lifetimes of 1000 hours or more.

CPC classification number: G01N21/31 , G01N33/2835
Abstract: Manufactures and methods implement wear components containing a subsurface underlying incipient failure indicator, machinery parts including at least one wear component containing a subsurface underlying incipient failure indicator, and mechanical systems including at least one machinery part including at least one wear component containing a subsurface underlying incipient failure indicator. An elastomeric seal has one or more failure indicators including a spectrally distinguishable element and/or molecule from operating-native constituent matter of a mechanical system underlying at one or more subsurface distances, including at least one subsurface distance within an incipient failure region. Abrasive wear of an elastomeric seals can expose subsurface strata having failure indicators embedded therein, each exposure causing a spectrally distinguishable element and/or molecule to mingle with lubricant of the mechanical system. Based on detecting the failure-indicating characteristic spectrum, the mechanical system can be removed from operation and one or more elastomeric seals replaced.
