Series EMD2 Enhanced Maxi-Duty Casters

Capacity Range: 22,400 – 36,800 lbs.

For those applications when you need more than 22,000 lbs. and forged steel wheels will work for your application, look no further than the Enhanced Maxi-Duty Caster Series.

The EMD Series is a hybrid of our long-time Maxi-Duty Series and our Ultra Maxi-Duty Series. The series incorporate the smaller mounting plate of the Maxi-Duty with the massive swivel construction of the UMD Series. The result is a less costly caster than the UMD yet with ample bulk to handle loads up to 36,800 lbs. The dual forged steel wheels are machined with a slight crown to enhance rollability and swiveling.

Quality Features & Specs

Swivel Construction 5/8" thick drop forged steel mounting plate (rigid plate 1/2" thick) joined with a 1" thick swivel base; 3/4" thick precision laser cut steel legs are continuously welded inside and outside the 1" thick swivel base.
Kingpin 1 1/4" diameter integrally forged with mounting plate guaranteed for life, prevents bending or breaking; threaded for special 1 1/4" combined CRS thrust spacer & slotted nut secured by roll pin for positive locking.
Main Load Bearing HPI thrust ball bearing with a 7" diameter rated to a comfortable 100,000 lbs.
Secondary Load Bearing 1 1/4" extra heavy precision tapered thrust bearing counteracts radial thrust.
Axle 1 1/2" diameter turned, ground, and polished with slotted nut and cotter pin. 1 1/4" diameter on 8" wheels.
Lubrication Fittings Ball-check type in swivel assembly and in wheel hubs.
