Johnson Manufacturing overhaul balls supply the downfall weight necessary to counter bearing friction and winch-to-boom-tip line weight.
Because these units must meet a wide range of field applications, we offer an equally wide range of unit sizes. It is in fact, one of the widest ranges available -- over 240 models, 35 through 1,478 pounds 3 through 30 tons W.L.L.

All Johnson Swivel overhaul balls call for periodic lubrication, with no disassebly required.

Midget Non-Swiveling Overhaul Balls. Among our more economical models, these small but husky units are ideal for light tonnage applications which demand top performance and downfall speed. Available are 3 and 5-ton capacities, with weights ranging from 36 to 49 pounds. Wedge sockets for the Type 6 are multi-purpose. Each has the flexibility of being used with more than one size wire rope through a simple change in wedge size.

Midget Swiveling Overhaul Balls. Johnson Blocks midget models OB-3JEM-28-4, OB-3JEM-28-6, and OB-3JEM-28-7 have an advantage in size, as well as capability. They are unusually short in overall length, the basic eye-top unit being only 13-7/16 inches. Other units in this low profile series include jaw types and the versatile wedge socket types.

Bottom Swivel Overhaul Balls, Type 3. The first overhaul ball ever offered by Johnson Blocks, the Type 3 is still widely used. The reason again, exceptional compactness. With wedge socket and swivel almost completely enclosed within the ball and pin assembly, it is 25 to 30 percent shorter in overall length than competive makes. It also offers the advantage of an open wedge socket that can be adapted to two or more sizes of wire rope, just by changing out the wedge. Type 3 Bottom swivel overhaul balls are available in capacities of 3 to 30 tons; weights of from 54 through 1,290 pounds. When ordering, always specify the wire rope size to be used. Johnson J-Latch standard.

Top Swivel Overhaul Balls, 4,5,6,7. The advantage of the top swivel overhaul ball lies in the ability of its upper fitting and attached wire rope to move independent of its ball and lower fitting.
Johnson Blocks introduced its first top swivel balls in 1966 in response to requests for units with more accessible upper fittings. From these have evolved the broad line of precision assemblies which this company now manufactures. In all, our offering consists of some 138 models with weights ranging from 37 through 1,478 pounds; capacities, from 3-3/4 through 30 tons. Interchangeable wedge sockets are standard on the Type 6, as is the Johnson J-Latch.

Overhaul Balls and Pins. Ball and pin assemblies are obtainable as replacement parts for Johnson Blocks overhaul balls or as add-on/conversion kits for Johnson Blocks swivels. Ranging in weight from 37 to 1,161 pounds, these units consist of cast iron ball, steel pin, and the necessary nuts and cotters.

Split Overhaul Balls. Johnson Blocks solit balls present a convenient and effective way to add overhaul weight directly to the wire rope. Made up of two cast iron halves which clamp to the line by means of bolts, these units are designed to fit 1/2 and 5/8 inch rope (50 pound weight) and 5/8, 3/4 and 7/8-inch rope (100 pound weight).
