  • Swivel Construction 
Forged steel top plate and fork base; 1/4" x 2" plate steel legs welded inside and outside to forged steel horn base.
  • Main Load Bearing 
2 9/16" diameter hardened and CNC-machined raceway with 3/8" balls.

The forged ring is cnc-machined with a precision groove to accept a large seal made from Nitrile butadiene rubber(NBR) designed to keep grease in and contaminants out.
  • Axle
1/2" diameter hex head with lock nut.
  • Brakes
- Keep safety manager happy with all-steel cam-actuated side foot brake (-FB), or heavy duty face contact brake (-ZB) for more positive locking. Other styles available. Select desired caster from selection table to see brake details.
  • Swivel Lock
- 4 Position (-4SL) convert swivel to rigid for straight line steering, robotically welded housing & CNC-milled slots assure long lasting, trouble-free performance.
  • Custom Engineering
- Hamilton engineers will custom design any caster to meet customer requirements.
 
The new Zero Fix Spinfinity™ Series casters represent a new class of the “best of breed” kingpinless design. The ZFWH Series represents Hamilton's answer to our customers asking for a highly durable maintenance-free kingpinless caster with the industry's most popular 4" x 5" mounting plate.

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 extreme loads.

All ZFWH Series casters are finished in red crimson and come standard with a choice of thirteen 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.
