Hamilton ZFFM Spinfinity Maintenance Free Casters

Spinfinity Maintenance-Free | Series ZFFM

Capacity Range: 600 – 3,200 lbs.

The all-new Spinfinity™ Series ZFFM casters are tough kingpinless casters designed for 3" wide wheels. The Series ZFFM is a beefed up version of our new ZFHS Series. The top plate and inner raceway are forged steel formed from one piece, providing a superior raceway for shock conditions. Once formed, the raceways are CNC-machined and then hardened to ensure a uniform depth in hardness of the swivel raceway. The hardening and the CNC-machining together produce an excellent swiveling caster under extra heavy loads.

All Spinfinity™ Series ZFFM casters are finished in a durable powder coated red crimson and come standard with a choice of ten different wheel types. Bearing selections are exclusive to double sealed precision ball bearings which like the swivel raceway are maintenance-free. Select with confidence knowing all of the casters in the chart below are classified as maintenance-free.
