Spinfinity Super Endurance Caster Series (ZFSEC) Are Impervious to Dirt

The new Spinfinity Super Endurance Caster Series (ZFSEC) is the next generation of Hamilton Caster's Super Endurance Caster (SEC) series.

The Spinfinity kingpinless brand is already synonymous with 100% maintenance-free performance in heavy-duty applications, and the newly rebranded ZFSEC series takes that legacy to the next level.

So what's the upgrade? Most notably, a heavy-duty V-Seal was added to the swivel raceway, rendering the rig resistant against dirt, debris, and moisture. This sealing creates smooth performance and extends the life of the caster. All ZFSEC casters are now 100% maintenance-free.

The ZFSEC series retains the swivel top plate and inner raceway made from forged steel for shock conditions. Sealed precision ball bearings are standard in all wheels, contributing to the maintenance-free performance of the series. Notably, zerk fittings have been eliminated, as the new design makes them unnecessary.
