Abstract:
A steering axle assembly includes a wheel end having a knuckle section comprising a first arm and a second arm each extending therefrom. The steering axle assembly includes an axle beam having a connecting end. A pin is disposed in respective bores of the first and second arms and of the connecting end. The steering axle assembly includes a self-lubricated bearing system that including a first tubular bushing, a second tubular busing and an annular thrust bearing. The self-lubricated bearing system has an adequate amount of lubricant therein at a beginning of life state and the amount of the lubricant being sufficient for an end of life state defined by at least one million miles of operation of the heavy duty truck, without replenishment of the lubricant.
Abstract:
A bearing is provided that includes a first ring having at least one first raceway defined by a radially inward facing surface of the first ring; and a second ring concentric with the first ring and having at least one second raceway defined by a radially outward facing surface of the second ring. The bearing includes a plurality of rolling elements disposed between the first and second rings. The rolling elements rollingly engage the first and second raceways. The first ring has a first gap therein and the second ring has a second gap therein. One or more race reliefs extend into the first raceway and/or the second raceway.
Abstract:
A bearing assembly includes an inner member having an outer engagement surface and an outer race. The outer race has an inner surface defining a first end and a second end and an inner engagement surface therebetween, the inner engagement surface is positioned on the outer engagement surface of the inner member. A first annular groove is formed in the inner surface, proximate one of the first end and the second end. A second annular groove is formed in the inner surface and is positioned axially inward from the first annular groove. An external seal is positioned in first annular groove and slidably engages the inner member. An internal seal is positioned in the second annular groove and slidingly engages the inner member.
Abstract:
An actuation system for deploying and retracting a lift assisting device of a leading edge of a wing of an aircraft including a track pivotally coupled to the lift assisting device. The track has first and second outer surfaces and side surfaces. The actuation system includes a shaft rotationally coupled within the wing of the aircraft and operable, in response to flight control signals, to deploy or retract the lift assisting device. The actuation system includes an actuator for actuating the lift assisting device, coupled to the shaft, between a retracted position to a deployed position along an arcuate path. The actuation system includes a plurality of track roller bearings rotatably contacting the first and second outer surfaces of the track to guide the track along the arcuate path. The plurality of track roller bearings includes one or more lined track roller assembly.

Abstract:
A cam follower for a ram of a metal can necker machine and a method of making the same. An outer ring has an outer ring bearing surface and an exterior surface defining a groove extending along at least a portion thereof. An inner ring is coaxially in the outer ring and has an inner ring bearing surface. A plurality of rolling elements is disposed in an annular cavity between the outer ring bearing surface and the inner ring bearing surface. The plurality of rolling elements are in rolling engagement with the outer ring bearing surface and the inner ring bearing surface so that the outer ring is rotatable relative to the inner ring about an axis of rotation. A least a portion of the tire is disposed in the groove to inhibit axial movement of the tire relative to the outer ring.
Abstract:
An end cap for a bearing assembly includes a first body portion having a substantially annular sealing surface positioned radially away from a central axis of the first body portion. The end cap includes a second body portion extending from the first body portion, the second body portion having at least one protrusion extending radially therefrom.
Abstract:
A bearing includes an inner race member having an end surface. An outer race member is disposed about the inner race member. The outer race member has an internal shoulder for engaging the end surface of the inner race member. The inner and outer race members are configured to define a raceway between them and to define a snap ring seat between them. There are cylindrical rollers in the raceway and a snap ring in the snap ring seat. The bearing may be provided as a follower head on a cam follower or may be eccentrically mounted on a drive shaft to serve as a cam. A cargo dolly may include such a cam near a wheel, to help the wheel overcome an obstacle. A bearing can be assembled by inserting the inner race member into the outer race member, disposing cylindrical rollers in the raceway and disposing a snap ring in the snap ring seat.
Abstract:
A bearing having a surface and a self-lubricating surface coating composition deposited on the surface, wherein the self-lubricating surface coating composition includes a curable acrylate composition having a metallic composition. The metallic composition having a metallic acrylate compound according to Formula I:
Abstract:
A conveyor chain including a chain pin having an exterior surface; a bearing having a generally tubular body portion having an exterior surface and an interior surface, the chain pin disposed in the generally tubular body portion of the bearing so that the interior surface of the bearing surrounds the exterior surface of the chain pin; and a low friction liner material secured to a surface selected from the exterior surface of said chain pin, the interior surface of the bearing, the exterior surface of the bearing, or combinations thereof.
