Hamilton EPSD Enhanced Precision Super Duty Caster

We work with industries that need to move extremely large parts and machinery that need the most rigid and resilient casters to help. That's why you can put your trust in our EPSD Enhanced Precision Super Duty Casters, which are part of our heavy-duty casters collection. It uses new technology that outperforms the conventional CNC-machined ball bearings, kingpinless, and unit load-bearing swivel constructions. Casters are constantly evolving to better suit the needs of each industry that requires them for their work. That's why you'll find new and improved designs with improved bearing elements that double the number of contact points.
