83 Series – 1700 Lbs Capacity – 6 x 7.5 Top Plate – Shock Absorbing
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.
Our 83 series shock absorbing lockable heavy duty casters have swivel sections that are constructed of high alloy steel and are precision machined for close tolerances and long life. The high strength chrome vanadium springs provide longer life through constant flexing and compressing.
The 83 series’ shock absorbing capabilities offer several benefits as well including noise reduction and cargo protection. Our spring loaded casters are designed for optimal spring deflection, maintaining a perfect balance of rigidity and shock absorption.
