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.
