The Poly-Soft® is formulated for a quieter operation and greater resistance to foreign objects and debris (F.O.D.). As the name implies, Poly-Soft® wheel tread hardness measures 82-85D (Shore A scale) vs. the harder Duralast® 90-95D (Shore A).The wheel has found popularity among automotive plants and those customers wanting to lower factory noise levels, and improve floor protection.

most forged steel and cold forged casters.

The chart below offers our most popular sizes, but this soft poly tread can also be molded to Hamilton's other standard cast iron, forged steel, and/or aluminum centers in finished sizes ranging from 3w" to 20" in diameter.
