Hamilton Enhanced Precision Super Duty Casters

Series EPSD
Enhanced Precision Super Duty Casters

Capacity Range: 2000 – 10,000 lbs.

The Enhanced Precision Super Duty (EPSD) Series is a handsome caster with good proportions and balance. The series is a significant upgrade from the PSD Series it replaces and is better positioned to outperform in applications suited between our Maxi-Duty (MD) and Extra Heavy Duty (EHD) Series.

The unit load bearing has been replaced with new HPI™ Swivel Technology that has been proven superior to designs with conventional unit load bearings. The new EPSD also features a slightly larger top plate with slotted holes to accommodate the former PSD Series bolt pattern and adds an additional bolt pattern popular in the industry.
