84 Series – 2500 Lbs Capacity – 6 x 7.5 Top Plate – Vertical Spring Mounted

Series 84

Build

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.
Top Plate: 6” x 7.5”

Overview

The 84 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 84 Series makes it an ideal choice for rugged jobs.

The 84 series vertical mounted spring caster excels in reducing noise and protecting cargo from unexpected shocks. Vertical mounted spring casters are ideal for pre-loading, because they are designed to not deflect until the pre-loaded capacity is exceeded. The vertically mounted springs are retained on a rod with threaded ends. The benefit of this design is that there will be no deflection of the springs when loaded with the rated load capacity.
