The Ergo-Glide (formerly named Poly-Soft®) wheel is formulated for a quieter operation and greater resistance to foreign objects and debris (F.O.D.). Ergo-Glide wheels have a softer tread hardness measuring 82-85 (Shore A scale) vs. the harder Duralast® 90-95 (Shore A).The wheel has found popularity among automotive plants and those customers wanting to lower factory noise levels, and improve floor protection.
Ergo-Glide wheels are also available PRONTO® with precision ball bearings in 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.
