-13- Spherical Joint With Flexible Seals Abstract Spherical joints of the type pivotally connecting each end of an equalizer bar to a track roller frame of a track-type vehicle require positive sealing of the joints during operation of the vehicle wherein the joint undergoes compound movements. Standard sealing assemblies therefor are prone to failure since they are subjected to tensile and compressive forces during operation thereof. A seal assembly substantially prevents the imposition of such forces thereon by including structure for permitting flexing thereof.
