Hamilton Casters Series WW

Whirlaway Casters

Capacity Range: 200 - 500 lbs.

Series: WW

The Whirlaway Series is the cold forged companion to the MS, GS, and 52 Series, but scaled down for 1-1/2" wide wheels. The two separate coined and case hardened raceways, joined by a heat treated rivet kingpin, make Whirlaway Swivel Casters top performers and sellers in the 500-600 lb. duty class.

Rugged 1/4" thick mounting plates are ideal for distortion-free welding to all types of mobile equipment, or bolt them on through slotted holes that fit two popular template patterns. All Series WW casters sport bright zinc plated finish.
