99 Series Casters – 50,000 Lbs Max Capacity – 14 x 14 Top Plate – Kingpin

Swivel Section: The yoke and top plates for this massive swivel section are manufactured by a drop-forged process from C-1045 steel. The kingpin is an integral forged part of the top plate. The swivel section has dual raceways which are precision machined at 9-inch and 12-inch diameters. The raceways are then heat treated to 40 + 2 Rc. The raceways are completed with 0.875-inch hardened precision ball bearings to complete the swivel section. A 1.5-inch precision thrust bearing is pressed over the kingpin to engage the yoke base. A 1.5-inch slotted nut is tightened to secure the swivel section and is then pinned in place.

Legs: 0.75 inch laser cut legs. When appropriate the legs are formed by a CNC press brake to enhance the strength. The legs are continuously welded both inside and outside for the greatest strength.

Kingpin: 1.5-inch diameter kingpin integrally forged into the top plate features a slotted adjusting nut and heavy duty 1.5-inch sealed and tapered thrust bearing.

Axle: 2 inch alloy steel with fine threads

Lubrication: Pre-lubricated before shipping.

Caster Concepts has a wide variety of caster options. Many of these not only improve function – but also provide safety and add longevity to the product. When considering safety options, the most common consideration would be caster locks, caster brakes, toe guards, and reinforced legs. Options that extend the life of a caster are primarily options that seal the bearing of the caster to prevent contamination of the precision parts.

Other options include threaded zerks for when an application is difficult and high level of maintenance is required and track brush wipers that keep debris from stopping movement or damaging a wheel. These options can be added at the time of manufacturing or after the caster is fully assembled.
