80 Series Casters – 5,000 Lbs Max Capacity – 6 x 7.5 Top Plate – Kingpin

Swivel Section: The yoke and top plate of this caster are manufactured by a drop forged process from C-1045 steel. The raceway is machined into the top plate, the kingpin is threaded and the yoke base raceway is also machined to a 5 inch diameter. The components are then heat treated to 40 + 2 Rc. A 1.25 inch precision tapered thrust bearing is pressed over the king pin and engages the yoke. Hardened ball bearings complete the load bearing raceway.

Kingpin: 1.25 inch integral forged kingpin, precision machined threads with slotted adjusted nut and pinned to correct tightness.

Legs: 3/8 inch by 4 inch laser cut legs, formed on a CNC press brake and continuously welded inside and outside for added strength.

Axle: 1 inch, Grade 5 axle with fine threads

Lubrication: Pre-lubricated before shipping

Wheels: 6 inch to 12 inch diameter wheels with widths from 2.5 inches to 4.0 inches. Bearings can be roller bearing, tapered bearing or precision ball bearing

Finish: Gold dichromate plating. Wet paint and powder coat paint available.

80 Series Caster


The 80 Series Extra Heavy Duty Casters are manufactured to withstand abusive applications. The heat treated raceways are designed to prevent brinelling of the raceways. The laser cut formed legs provide additional strength when side loading or skidding is prevalent in the application. The exceptional strength of the 80 Series makes it an ideal choice for rugged jobs.

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.
