Workhorse Casters

Capacity Range: 300 - 2000 lbs.

  • Swivel Construction 
1/4" thick drop forged steel mounting plate; 1/4" x 2" plate steel legs robotically welded inside and outside to forged steel horn base.
  • Kingpin 
Sturdy 3/4" diameter integrally forged with mounting plate, guaranteed for life, and threaded for 3/4" lock nut.
  • Main Load Bearing 
CNC-machined 2 9/16" diameter raceway; 3/8" diameter hardened and polished steel balls.
  • Secondary Load Bearing 
3/4" precision tapered thrust bearing counteracts radial thrust.
  • Lubrication Fittings
Ball-check type in swivel assembly and in wheel hubs with tapered or straight roller bearings.
  • 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.
  • Sealed Swivel Assembly
(-SS) - prolongs caster life in harsh environments.
  • Wheel Bearing Seals
(-BS) - prolong wheel life in harsh environments.
  • Spring Loaded Models
  • Heat Treated Raceways
Reduce wear in power-towed applications.
  • Custom Engineering
Hamilton engineers will custom design any caster to meet customer requirements.
 
The Workhorse combines the forged steel strength of Hamilton's HS Caster Series and the bolt hole pattern of the Standard Duty 52 Series. The drop forged steel swivel caster construction includes a 3/4" diameter integrally forged steel kingpin (guaranteed for life!), and a precision secondary load bearing.

When your application is too tough for the Standard Duty 52 Series, but you need to match its specifications, Workhorse is up to the challenge.
Hamilton Precision and Durability
The Workhorse Series (WH) is backed by Hamilton’s Three Year Product Warranty. Refer to selection table for qualifying wheels.
