Hamilton® Duralast™ Wheel 6 x 3 - 3/4" Ball Bearing

This polyurethane wheel is harder than standard 95A poly, so it rolls more easily and carries up to 30& more capacity. In addition, they repel foreign objects and debris.

This wheel is liquid cast to a thickness of approximately 1/2" and chemically bonded onto heavy-duty iron wheel centers. The distinctive green treads are chemically inert, non-sparking, non-conductive, impervious to ozone, grease and most oil and solvents, and will not mark floors.

Features: Directly mount to T-Slot with no base plate required Compatible with 80/20 T-Slot profile series 15, 30, 40, 45 Max Load Capacity: 350 lbs Temperature Rating: -20° to 180° F Wheel Material: Polyurethane Tread on Polyolefin Core Wheel Style: 4" Diameter x 1.23" wide Wheel Durometer: 60 (+/-5) Shore D Bearing Type: Precision Ball Bearing

A fiber filled phenolic resin, molded under extreme pressure, gives this wheel the ability to carry heavy loads without damaging floors in intermittent service. They are non-marking, resist corrosion from oil, water, grease and commonly used acids or solvents, and will not spark. Can be operated continuously in temperatures ranging from -50 to 260 degrees F and intermittently to 300 degrees F.

This Poly-Soft wheel is formulated for a quieter operation and greater resistance to foreign objects and debris. As the name implies, wheel tread hardness measures 82-85 Durometer. The livelier material cushions the load thereby reducing vibration on the load resulting in a quieter ride and less wear and tear on the caster and cargo. In addition, the new urethane has been engineered to repel steel chips, nuts, bolts, pins, etc., and takes on "super ball" properties that offer an energized wheel.
