Miller SOLID-BALL® Headache Ball Assemblies are the only overhaul ball assemblies on the market which use a long-life, multiple angular contact ball bearing swivel, as opposed to a single thrust bearing swivel. Mounted above the ball, this low friction swivel prevents both load and ball from spinning. Miller's unique Y-Link® angular contact bearing swivel with direct lubrication fitting assures smooth operation and the longest working life by far. Standard working loads are available to 35 tons with overhaul weights up to 1450 lbs. 5:1 design factor. Available with eye, clevis, or with Miller's exclusive integrated wedge socket connection.
