4" X 1.25" Gray Polyurethane on Polyolefin Wheel - Rigid Caster - 325 lbs Capacity Our 1300 Series Casters are Economical and Versatile. These casters are perfect for material handling, maintenance carts, linen carts, bakeries, food service, dollies, and more! We use heavy gauge cold rolled steel and beautiful zinc plated finish for superior rust and corrosion resistance.The wheel is a gray non-marking polyurethane tread mechanically locked to a polyolefin core. The polyurethane wheel has a sealed precision bearing for easy initiation, increased ergonomics, and a full thread guard which protects the accumulation of linen, hair, string, and debris from being wrapped around the axle or bearing. Full thread guards are great for many applications where the floor has debris, such as the textile industry, to name one. The polyurethane tread wheel is chemically resistant and will not disintegrate like other wheels due to harsh chemicals or washdown applications. The temperature range of this wheel is -20F to 180F, and the hardness (durometer) is a Shore D 60 (+/-5).Matching Swivel Version Here
